= Authorization Migrations

The following steps relate to changes around how authorization is performed.

== Use `AuthorizationManager` for Method Security

xref:servlet/authorization/method-security.adoc[Method Security] has been xref:servlet/authorization/method-security.adoc#jc-enable-method-security[simplified] through {security-api-url}org/springframework/security/authorization/AuthorizationManager.html[the `AuthorizationManager` API] and direct use of Spring AOP.

Should you run into trouble with making these changes, note that `@EnableGlobalMethodSecurity`, while deprecated, will not be removed in 6.0, allowing you to opt out by sticking with the old annotation.

[[servlet-replace-globalmethodsecurity-with-methodsecurity]]
=== Replace xref:servlet/authorization/method-security.adoc#jc-enable-global-method-security[global method security] with xref:servlet/authorization/method-security.adoc#jc-enable-method-security[method security]

{security-api-url}org/springframework/security/config/annotation/method/configuration/EnableGlobalMethodSecurity.html[`@EnableGlobalMethodSecurity`] and xref:servlet/appendix/namespace/method-security.adoc#nsa-global-method-security[`<global-method-security>`] are deprecated in favor of {security-api-url}org/springframework/security/config/annotation/method/configuration/EnableMethodSecurity.html[`@EnableMethodSecurity`] and xref:servlet/appendix/namespace/method-security.adoc#nsa-method-security[`<method-security>`], respectively.
The new annotation and XML element activate Spring's xref:servlet/authorization/method-security.adoc#jc-enable-method-security[pre-post annotations] by default and use `AuthorizationManager` internally.

This means that the following two listings are functionally equivalent:

====
.Java
[source,java,role="primary"]
----
@EnableGlobalMethodSecurity(prePostEnabled = true)
----

.Kotlin
[source,kotlin,role="secondary"]
----
@EnableGlobalMethodSecurity(prePostEnabled = true)
----

.Xml
[source,xml,role="secondary"]
----
<global-method-security pre-post-enabled="true"/>
----
====

and:

====
.Java
[source,java,role="primary"]
----
@EnableMethodSecurity
----

.Kotlin
[source,kotlin,role="secondary"]
----
@EnableMethodSecurity
----

.Xml
[source,xml,role="secondary"]
----
<method-security/>
----
====

For applications not using the pre-post annotations, make sure to turn it off to avoid activating unwanted behavior.

For example, a listing like:

====
.Java
[source,java,role="primary"]
----
@EnableGlobalMethodSecurity(securedEnabled = true)
----

.Kotlin
[source,kotlin,role="secondary"]
----
@EnableGlobalMethodSecurity(securedEnabled = true)
----

.Xml
[source,xml,role="secondary"]
----
<global-method-security secured-enabled="true"/>
----
====

should change to:

====
.Java
[source,java,role="primary"]
----
@EnableMethodSecurity(securedEnabled = true, prePostEnabled = false)
----

.Kotlin
[source,kotlin,role="secondary"]
----
@EnableMethodSecurity(securedEnabled = true, prePostEnabled = false)
----

.Xml
[source,xml,role="secondary"]
----
<method-security secured-enabled="true" pre-post-enabled="false"/>
----
====

=== Use a Custom `@Bean` instead of subclassing `DefaultMethodSecurityExpressionHandler`

As a performance optimization, a new method was introduced to `MethodSecurityExpressionHandler` that takes a `Supplier<Authentication>` instead of an `Authentication`.

This allows Spring Security to defer the lookup of the `Authentication`, and is taken advantage of automatically when you use `@EnableMethodSecurity` instead of `@EnableGlobalMethodSecurity`.

However, let's say that your code extends `DefaultMethodSecurityExpressionHandler` and overrides `createSecurityExpressionRoot(Authentication, MethodInvocation)` to return a custom `SecurityExpressionRoot` instance.
This will no longer work because the arrangement that `@EnableMethodSecurity` sets up calls `createEvaluationContext(Supplier<Authentication>, MethodInvocation)` instead.

Happily, such a level of customization is often unnecessary.
Instead, you can create a custom bean with the authorization methods that you need.

For example, let's say you are wanting a custom evaluation of `@PostAuthorize("hasAuthority('ADMIN')")`.
You can create a custom `@Bean` like this one:

====
.Java
[source,java,role="primary"]
----
class MyAuthorizer {
	boolean isAdmin(MethodSecurityExpressionOperations root) {
		boolean decision = root.hasAuthority("ADMIN");
		// custom work ...
        return decision;
	}
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
class MyAuthorizer {
	fun isAdmin(val root: MethodSecurityExpressionOperations): boolean {
		val decision = root.hasAuthority("ADMIN");
		// custom work ...
        return decision;
	}
}
----
====

and then refer to it in the annotation like so:

====
.Java
[source,java,role="primary"]
----
@PreAuthorize("@authz.isAdmin(#root)")
----

.Kotlin
[source,kotlin,role="secondary"]
----
@PreAuthorize("@authz.isAdmin(#root)")
----
====

==== I'd still prefer to subclass `DefaultMethodSecurityExpressionHandler`

If you must continue subclassing `DefaultMethodSecurityExpressionHandler`, you can still do so.
Instead, override the `createEvaluationContext(Supplier<Authentication>, MethodInvocation)` method like so:

====
.Java
[source,java,role="primary"]
----
@Component
class MyExpressionHandler extends DefaultMethodSecurityExpressionHandler {
    @Override
    public EvaluationContext createEvaluationContext(
            Supplier<Authentication> authentication, MethodInvocation mi) {
		StandardEvaluationContext context = (StandardEvaluationContext) super.createEvaluationContext(authentication, mi);
        MySecurityExpressionRoot root = new MySecurityExpressionRoot(authentication, invocation);
	    root.setPermissionEvaluator(getPermissionEvaluator());
	    root.setTrustResolver(new AuthenticationTrustResolverImpl());
        root.setRoleHierarchy(getRoleHierarchy());
        context.setRootObject(root);
        return context;
    }
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
@Component
class MyExpressionHandler: DefaultMethodSecurityExpressionHandler {
    override fun createEvaluationContext(val authentication: Supplier<Authentication>,
        val mi: MethodInvocation): EvaluationContext {
		val context = super.createEvaluationContext(authentication, mi) as StandardEvaluationContext;
        val root = new MySecurityExpressionRoot(authentication, invocation);
	    root.setPermissionEvaluator(getPermissionEvaluator());
	    root.setTrustResolver(new AuthenticationTrustResolverImpl());
        root.setRoleHierarchy(getRoleHierarchy());
        context.setRootObject(root);
        return context;
    }
}
----
====

==== Opt-out Steps

If you need to opt-out of these changes, you can use `@EnableGlobalMethodSecurity` instead of `@EnableMethodSecurity`

[[servlet-replace-permissionevaluator-bean-with-methodsecurityexpression-handler]]
=== Publish a `MethodSecurityExpressionHandler` instead of a `PermissionEvaluator`

`@EnableMethodSecurity` does not pick up a `PermissionEvaluator`.
This helps keep its API simple.

If you have a custom {security-api-url}org/springframework/security/access/PermissionEvaluator.html[`PermissionEvaluator`] `@Bean`, please change it from:

====
.Java
[source,java,role="primary"]
----
@Bean
static PermissionEvaluator permissionEvaluator() {
	// ... your evaluator
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
companion object {
	@Bean
	fun permissionEvaluator(): PermissionEvaluator {
		// ... your evaluator
	}
}
----
====

to:

====
.Java
[source,java,role="primary"]
----
@Bean
static MethodSecurityExpressionHandler expressionHandler() {
	var expressionHandler = new DefaultMethodSecurityExpressionHandler();
	expressionHandler.setPermissionEvaluator(myPermissionEvaluator);
	return expressionHandler;
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
companion object {
	@Bean
	fun expressionHandler(): MethodSecurityExpressionHandler {
		val expressionHandler = DefaultMethodSecurityExpressionHandler
		expressionHandler.setPermissionEvaluator(myPermissionEvaluator)
		return expressionHandler
	}
}
----
====

=== Replace any custom method-security ``AccessDecisionManager``s

Your application may have a custom {security-api-url}org/springframework/security/access/AccessDecisionManager.html[`AccessDecisionManager`] or {security-api-url}org/springframework/security/access/AccessDecisionVoter.html[`AccessDecisionVoter`] arrangement.
The preparation strategy will depend on your reason for each arrangement.
Read on to find the best match for your situation.

==== I use `UnanimousBased`

If your application uses {security-api-url}org/springframework/security/access/vote/UnanimousBased.html[`UnanimousBased`] with the default voters, you likely need do nothing since unanimous-based is the default behavior with {security-api-url}org/springframework/security/config/annotation/method/configuration/EnableMethodSecurity.html[`@EnableMethodSecurity`].

However, if you do discover that you cannot accept the default authorization managers, you can use `AuthorizationManagers.allOf` to compose your own arrangement.
Having done that, please follow the details in the reference manual for xref:servlet/authorization/method-security.adoc#jc-method-security-custom-authorization-manager[adding a custom `AuthorizationManager`].

==== I use `AffirmativeBased`

If your application uses {security-api-url}org/springframework/security/access/vote/AffirmativeBased.html[`AffirmativeBased`], then you can construct an equivalent {security-api-url}org/springframework/security/authorization/AuthorizationManager.html[`AuthorizationManager`], like so:

====
.Java
[source,java,role="primary"]
----
AuthorizationManager<MethodInvocation> authorization = AuthorizationManagers.anyOf(
		// ... your list of authorization managers
)
----

.Kotlin
[source,kotlin,role="secondary"]
----
val authorization = AuthorizationManagers.anyOf(
		// ... your list of authorization managers
)
----
====

Once you have implemented `AuthorizationManager`, please follow the details in the reference manual for xref:servlet/authorization/method-security.adoc#jc-method-security-custom-authorization-manager[adding a custom `AuthorizationManager`].

==== I use `ConsensusBased`

There is no framework-provided equivalent for {security-api-url}org/springframework/security/access/vote/ConsensusBased.html[`ConsensusBased`].
In that case, please implement a composite {security-api-url}org/springframework/security/authorization/AuthorizationManager.html[`AuthorizationManager`] that takes the set of delegate ``AuthorizationManager``s into account.

Once you have implemented `AuthorizationManager`, please follow the details in the reference manual for xref:servlet/authorization/method-security.adoc#jc-method-security-custom-authorization-manager[adding a custom `AuthorizationManager`].

==== I use a custom `AccessDecisionVoter`

You should either change the class to implement {security-api-url}org/springframework/security/authorization/AuthorizationManager.html[`AuthorizationManager`] or create an adapter.

Without knowing what your custom voter is doing, it is impossible to recommend a general-purpose solution.
By way of example, though, here is what adapting {security-api-url}org/springframework/security/access/SecurityMetadataSource.html[`SecurityMetadataSource`] and {security-api-url}org/springframework/security/access/AccessDecisionVoter.html[`AccessDecisionVoter`] for `@PreAuthorize` would look like:

====
.Java
[source,java,role="primary"]
----
public final class PreAuthorizeAuthorizationManagerAdapter implements AuthorizationManager<MethodInvocation> {
    private final SecurityMetadataSource metadata;
    private final AccessDecisionVoter voter;

    public PreAuthorizeAuthorizationManagerAdapter(MethodSecurityExpressionHandler expressionHandler) {
        ExpressionBasedAnnotationAttributeFactory attributeFactory =
                new ExpressionBasedAnnotationAttributeFactory(expressionHandler);
        this.metadata = new PrePostAnnotationSecurityMetadataSource(attributeFactory);
        ExpressionBasedPreInvocationAdvice expressionAdvice = new ExpressionBasedPreInvocationAdvice();
        expressionAdvice.setExpressionHandler(expressionHandler);
        this.voter = new PreInvocationAuthorizationAdviceVoter(expressionAdvice);
    }

    public AuthorizationDecision check(Supplier<Authentication> authentication, MethodInvocation invocation) {
        List<ConfigAttribute> attributes = this.metadata.getAttributes(invocation, AopUtils.getTargetClass(invocation.getThis()));
        int decision = this.voter.vote(authentication.get(), invocation, attributes);
        if (decision == ACCESS_GRANTED) {
            return new AuthorizationDecision(true);
        }
        if (decision == ACCESS_DENIED) {
            return new AuthorizationDecision(false);
        }
        return null; // abstain
    }
}
----
====

Once you have implemented `AuthorizationManager`, please follow the details in the reference manual for xref:servlet/authorization/method-security.adoc#jc-method-security-custom-authorization-manager[adding a custom `AuthorizationManager`].

==== I use `AfterInvocationManager` or `AfterInvocationProvider`

{security-api-url}org/springframework/security/access/intercept/AfterInvocationManager.html;[`AfterInvocationManager`] and {security-api-url}org/springframework/security/access/intercept/AfterInvocationProvider.html[`AfterInvocationProvider`] make an authorization decision about an invocation's result.
For example, in the case of method invocation, these make an authorization decision about a method's return value.

In Spring Security 3.0, authorization decision-making was standardized into the xref:servlet/authorization/method-security.adoc[`@PostAuthorize` and `@PostFilter` annotations].
`@PostAuthorize` is for deciding whether the return value as a whole was permitted to be returned.
`@PostFilter` is for filtering individual entries from a returned collection, array, or stream.

These two annotations should serve most needs, and you are encouraged to migrate to one or both of them since `AfterInvocationProvider` and `AfterInvocationManager` are now deprecated.

If you've implemented your own `AfterInvocationManager` or `AfterInvocationProvider`, you should first ask yourself what it is trying to do.
If it is trying to authorize the return type, <<_i_use_a_custom_accessdecisionvoter,consider implementing `AuthorizationManager<MethodInvocationResult>` and using `AfterMethodAuthorizationManagerInterceptor`>>. Or publishing a custom bean and using `@PostAuthorize("@myBean.authorize(#root)")`.

If it is trying to filter, then consider publishing a custom bean and using `@PostFilter("@mybean.authorize(#root)")`.
Or, if needed, you can implement your own `MethodInterceptor`, taking a look at `PostFilterAuthorizationMethodInterceptor` and `PrePostMethodSecurityConfiguration` for an example.

==== I use `RunAsManager`

There is currently https://github.com/spring-projects/spring-security/issues/11331[no replacement for `RunAsManager`] though one is being considered.

It is quite straightforward to adapt a `RunAsManager`, though, to the `AuthorizationManager` API, if needed.

Here is some pseudocode to get you started:

====
.Java
[source,java,role="primary"]
----
public final class RunAsAuthorizationManagerAdapter<T> implements AuthorizationManager<T> {
	private final RunAsManager runAs = new RunAsManagerImpl();
	private final SecurityMetadataSource metadata;
    private final AuthorizationManager<T> authorization;

    // ... constructor

    public AuthorizationDecision check(Supplier<Authentication> authentication, T object) {
		Supplier<Authentication> wrapped = (auth) -> {
			List<ConfigAttribute> attributes = this.metadata.getAttributes(object);
			return this.runAs.buildRunAs(auth, object, attributes);
		};
		return this.authorization.check(wrapped, object);
    }
}
----
====

Once you have implemented `AuthorizationManager`, please follow the details in the reference manual for xref:servlet/authorization/method-security.adoc#jc-method-security-custom-authorization-manager[adding a custom `AuthorizationManager`].

[[servlet-check-for-annotationconfigurationexceptions]]
=== Check for ``AnnotationConfigurationException``s

`@EnableMethodSecurity` and `<method-security>` activate stricter enforcement of Spring Security's non-repeatable or otherwise incompatible annotations.
If after moving to either you see ``AnnotationConfigurationException``s in your logs, follow the instructions in the exception message to clean up your application's method security annotation usage.

== Use `AuthorizationManager` for Message Security

xref:servlet/integrations/websocket.adoc[Message Security] has been xref:servlet/integrations/websocket.adoc#websocket-configuration[improved] through {security-api-url}org/springframework/security/authorization/AuthorizationManager.html[the `AuthorizationManager` API] and direct use of Spring AOP.

Should you run into trouble with making these changes, you can follow the <<servlet-authorizationmanager-messages-opt-out,opt out steps>> at the end of this section.

=== Ensure all messages have defined authorization rules

The now-deprecated {security-api-url}org/springframework/security/config/annotation/web/socket/AbstractSecurityWebSocketMessageBrokerConfigurer.html[message security support] permits all messages by default.
xref:servlet/integrations/websocket.adoc[The new support] has the stronger default of denying all messages.

To prepare for this, ensure that authorization rules exist are declared for every request.

For example, an application configuration like:

====
.Java
[source,java,role="primary"]
----
@Override
protected void configureInbound(MessageSecurityMetadataSourceRegistry messages) {
    messages
        .simpDestMatchers("/user/queue/errors").permitAll()
        .simpDestMatchers("/admin/**").hasRole("ADMIN");
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
override fun configureInbound(messages: MessageSecurityMetadataSourceRegistry) {
    messages
        .simpDestMatchers("/user/queue/errors").permitAll()
        .simpDestMatchers("/admin/**").hasRole("ADMIN")
}
----

.Xml
[source,xml,role="secondary"]
----
<websocket-message-broker>
    <intercept-message pattern="/user/queue/errors" access="permitAll"/>
    <intercept-message pattern="/admin/**" access="hasRole('ADMIN')"/>
</websocket-message-broker>
----
====

should change to:

====
.Java
[source,java,role="primary"]
----
@Override
protected void configureInbound(MessageSecurityMetadataSourceRegistry messages) {
    messages
        .simpTypeMatchers(CONNECT, DISCONNECT, UNSUBSCRIBE).permitAll()
        .simpDestMatchers("/user/queue/errors").permitAll()
        .simpDestMatchers("/admin/**").hasRole("ADMIN")
        .anyMessage().denyAll();
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
override fun configureInbound(messages: MessageSecurityMetadataSourceRegistry) {
    messages
        .simpTypeMatchers(CONNECT, DISCONNECT, UNSUBSCRIBE).permitAll()
        .simpDestMatchers("/user/queue/errors").permitAll()
        .simpDestMatchers("/admin/**").hasRole("ADMIN")
        .anyMessage().denyAll()
}
----

.Xml
[source,xml,role="secondary"]
----
<websocket-message-broker>
    <intercept-message type="CONNECT" access="permitAll"/>
    <intercept-message type="DISCONNECT" access="permitAll"/>
    <intercept-message type="UNSUBSCRIBE" access="permitAll"/>
    <intercept-message pattern="/user/queue/errors" access="permitAll"/>
    <intercept-message pattern="/admin/**" access="hasRole('ADMIN')"/>
    <intercept-message pattern="/**" access="denyAll"/>
</websocket-message-broker>
----
====

=== Add `@EnableWebSocketSecurity`

[NOTE]
====
If you want to have CSRF disabled and you are using Java configuration, the migration steps are slightly different.
Instead of using `@EnableWebSocketSecurity`, you will override the appropriate methods in `WebSocketMessageBrokerConfigurer` yourself.
Please see xref:servlet/integrations/websocket.adoc#websocket-sameorigin-disable[the reference manual] for details about this step.
====

If you are using Java Configuration, add {security-api-url}org/springframework/security/config/annotation/web/socket/EnableWebSocketSecurity.html[`@EnableWebSocketSecurity`] to your application.

For example, you can add it to your websocket security configuration class, like so:

====
.Java
[source,java,role="primary"]
----
@EnableWebSocketSecurity
@Configuration
public class WebSocketSecurityConfig extends AbstractSecurityWebSocketMessageBrokerConfigurer {
	// ...
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
@EnableWebSocketSecurity
@Configuration
class WebSocketSecurityConfig: AbstractSecurityWebSocketMessageBrokerConfigurer() {
	// ...
}
----
====

This will make a prototype instance of `MessageMatcherDelegatingAuthorizationManager.Builder` available to encourage configuration by composition instead of extension.

=== Use an `AuthorizationManager<Message<?>>` instance

To start using `AuthorizationManager`, you can set the `use-authorization-manager` attribute in XML or you can publish an `AuthorizationManager<Message<?>>` `@Bean` in Java.

For example, the following application configuration:

====
.Java
[source,java,role="primary"]
----
@Override
protected void configureInbound(MessageSecurityMetadataSourceRegistry messages) {
    messages
        .simpTypeMatchers(CONNECT, DISCONNECT, UNSUBSCRIBE).permitAll()
        .simpDestMatchers("/user/queue/errors").permitAll()
        .simpDestMatchers("/admin/**").hasRole("ADMIN")
        .anyMessage().denyAll();
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
override fun configureInbound(messages: MessageSecurityMetadataSourceRegistry) {
    messages
        .simpTypeMatchers(CONNECT, DISCONNECT, UNSUBSCRIBE).permitAll()
        .simpDestMatchers("/user/queue/errors").permitAll()
        .simpDestMatchers("/admin/**").hasRole("ADMIN")
        .anyMessage().denyAll()
}
----

.Xml
[source,xml,role="secondary"]
----
<websocket-message-broker>
    <intercept-message type="CONNECT" access="permitAll"/>
    <intercept-message type="DISCONNECT" access="permitAll"/>
    <intercept-message type="UNSUBSCRIBE" access="permitAll"/>
    <intercept-message pattern="/user/queue/errors" access="permitAll"/>
    <intercept-message pattern="/admin/**" access="hasRole('ADMIN')"/>
    <intercept-message pattern="/**" access="denyAll"/>
</websocket-message-broker>
----
====

changes to:

====
.Java
[source,java,role="primary"]
----
@Bean
AuthorizationManager<Message<?>> messageSecurity(MessageMatcherDelegatingAuthorizationManager.Builder messages) {
    messages
        .simpTypeMatchers(CONNECT, DISCONNECT, UNSUBSCRIBE).permitAll()
        .simpDestMatchers("/user/queue/errors").permitAll()
        .simpDestMatchers("/admin/**").hasRole("ADMIN")
        .anyMessage().denyAll();
	return messages.build();
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
@Bean
fun messageSecurity(val messages: MessageMatcherDelegatingAuthorizationManager.Builder): AuthorizationManager<Message<?>> {
    messages
        .simpTypeMatchers(CONNECT, DISCONNECT, UNSUBSCRIBE).permitAll()
        .simpDestMatchers("/user/queue/errors").permitAll()
        .simpDestMatchers("/admin/**").hasRole("ADMIN")
        .anyMessage().denyAll()
    return messages.build()
}
----

.Xml
[source,xml,role="secondary"]

<websocket-message-broker use-authorization-manager="true">
    <intercept-message type="CONNECT" access="permitAll"/>
    <intercept-message type="DISCONNECT" access="permitAll"/>
    <intercept-message type="UNSUBSCRIBE" access="permitAll"/>
    <intercept-message pattern="/user/queue/errors" access="permitAll"/>
    <intercept-message pattern="/admin/**" access="hasRole('ADMIN')"/>
    <intercept-message pattern="/**" access="denyAll"/>
</websocket-message-broker>
----
====

=== Stop Implementing `AbstractSecurityWebSocketMessageBrokerConfigurer`

If you are using Java configuration, you can now simply extend `WebSocketMessageBrokerConfigurer`.

For example, if your class that extends `AbstractSecurityWebSocketMessageBrokerConfigurer` is called `WebSocketSecurityConfig`, then:

====
.Java
[source,java,role="primary"]
----
@EnableWebSocketSecurity
@Configuration
public class WebSocketSecurityConfig extends AbstractSecurityWebSocketMessageBrokerConfigurer {
	// ...
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
@EnableWebSocketSecurity
@Configuration
class WebSocketSecurityConfig: AbstractSecurityWebSocketMessageBrokerConfigurer() {
	// ...
}
----
====

changes to:

====
.Java
[source,java,role="primary"]
----
@EnableWebSocketSecurity
@Configuration
public class WebSocketSecurityConfig implements WebSocketMessageBrokerConfigurer {
	// ...
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
@EnableWebSocketSecurity
@Configuration
class WebSocketSecurityConfig: WebSocketMessageBrokerConfigurer {
	// ...
}
----
====

[[servlet-authorizationmanager-messages-opt-out]]
=== Opt-out Steps

In case you had trouble, take a look at these scenarios for optimal opt out behavior:

==== I cannot declare an authorization rule for all requests

If you are having trouble setting an `anyRequest` authorization rule of `denyAll`, please use {security-api-url}org/springframework/security/messaging/access/intercept/MessageMatcherDelegatingAuthorizationManager.Builder.Constraint.html#permitAll()[`permitAll`] instead, like so:

====
.Java
[source,java,role="primary"]
----
@Bean
AuthorizationManager<Message<?>> messageSecurity(MessageMatcherDelegatingAuthorizationManager.Builder messages) {
    messages
        .simpDestMatchers("/user/queue/errors").permitAll()
        .simpDestMatchers("/admin/**").hasRole("ADMIN")
        // ...
        .anyMessage().permitAll();
	return messages.build();
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
@Bean
fun messageSecurity(val messages: MessageMatcherDelegatingAuthorizationManager.Builder): AuthorizationManager<Message<?>> {
    messages
        .simpDestMatchers("/user/queue/errors").permitAll()
        .simpDestMatchers("/admin/**").hasRole("ADMIN")
        // ...
        .anyMessage().permitAll();
    return messages.build()
}
----

.Xml
[source,xml,role="secondary"]
----
<websocket-message-broker use-authorization-manager="true">
    <intercept-message pattern="/user/queue/errors" access="permitAll"/>
    <intercept-message pattern="/admin/**" access="hasRole('ADMIN')"/>
    <!-- ... -->
    <intercept-message pattern="/**" access="permitAll"/>
</websocket-message-broker>
----
====

==== I cannot get CSRF working, need some other `AbstractSecurityWebSocketMessageBrokerConfigurer` feature, or am having trouble with `AuthorizationManager`

In the case of Java, you may continue using `AbstractMessageSecurityWebSocketMessageBrokerConfigurer`.
Even though it is deprecated, it will not be removed in 6.0.

In the case of XML, you can opt out of `AuthorizationManager` by setting `use-authorization-manager="false"`:

====
.Xml
[source,xml,role="secondary"]
----
<websocket-message-broker>
    <intercept-message pattern="/user/queue/errors" access="permitAll"/>
    <intercept-message pattern="/admin/**" access="hasRole('ADMIN')"/>
</websocket-message-broker>
----
====

to:

====
.Xml
[source,xml,role="secondary"]
----
<websocket-message-broker use-authorization-manager="false">
    <intercept-message pattern="/user/queue/errors" access="permitAll"/>
    <intercept-message pattern="/admin/**" access="hasRole('ADMIN')"/>
</websocket-message-broker>
----

== Use `AuthorizationManager` for Request Security

xref:servlet/authorization/authorize-requests.adoc[HTTP Request Security] has been xref:servlet/authorization/authorize-http-requests.adoc[simplified] through {security-api-url}org/springframework/security/authorization/AuthorizationManager.html[the `AuthorizationManager` API].

Should you run into trouble with making these changes, you can follow the <<servlet-authorizationmanager-requests-opt-out,opt out steps>> at the end of this section.

=== Ensure that all requests have defined authorization rules

In Spring Security 5.8 and earlier, requests with no authorization rule are permitted by default.
It is a stronger security position to deny by default, thus requiring that authorization rules be clearly defined for every endpoint.
As such, in 6.0, Spring Security by default denies any request that is missing an authorization rule.

The simplest way to prepare for this change is to introduce an appropriate {security-api-url}org/springframework/security/config/annotation/web/AbstractRequestMatcherRegistry.html#anyRequest()[`anyRequest`] rule as the last authorization rule.
The recommendation is {security-api-url}org/springframework/security/config/annotation/web/configurers/ExpressionUrlAuthorizationConfigurer.AuthorizedUrl.html#denyAll()[`denyAll`] since that is the implied 6.0 default.

[NOTE]
====
You may already have an `anyRequest` rule defined that you are happy with in which case this step can be skipped.
====

Adding `denyAll` to the end looks like changing:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeRequests((authorize) -> authorize
        .filterSecurityInterceptorOncePerRequest(true)
        .mvcMatchers("/app/**").hasRole("APP")
        // ...
    )
    // ...

If you have already migrated to `authorizeHttpRequests`, the recommended change is the same.

=== Switch to `AuthorizationManager`

To opt in to using `AuthorizationManager`, you can use `authorizeHttpRequests` or xref:servlet/appendix/namespace/http.adoc#nsa-http-use-authorization-manager[`use-authorization-manager`] for Java or XML, respectively.

Change:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeRequests((authorize) -> authorize
        .filterSecurityInterceptorOncePerRequest(true)
        .mvcMatchers("/app/**").hasRole("APP")

=== Migrate SpEL expressions to `AuthorizationManager`

For authorization rules, Java tends to be easier to test and maintain than SpEL.
As such, `authorizeHttpRequests` does not have a method for declaring a `String` SpEL.

Instead, you can implement your own `AuthorizationManager` implementation or use `WebExpressionAuthorizationManager`.

For completeness, both options will be demonstrated.

First, if you have the following SpEL:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeRequests((authorize) -> authorize
        .filterSecurityInterceptorOncePerRequest(true)
        .mvcMatchers("/complicated/**").access("hasRole('ADMIN') || hasAuthority('SCOPE_read')")
        // ...
        .anyRequest().denyAll()
    )
    // ...
----

.Kotlin
[source,kotlin,role="secondary"]
----
http {
    authorizeRequests {
        filterSecurityInterceptorOncePerRequest = true
        authorize("/complicated/**", access("hasRole('ADMIN') || hasAuthority('SCOPE_read')"))
        // ...
        authorize(anyRequest, denyAll)
    }
}
----
====

Then you can compose your own `AuthorizationManager` with Spring Security authorization primitives like so:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeHttpRequests((authorize) -> authorize
        .shouldFilterAllDispatcherTypes(false)
        .mvcMatchers("/complicated/**").access(anyOf(hasRole("ADMIN"), hasAuthority("SCOPE_read"))
        // ...
        .anyRequest().denyAll()
    )
    // ...
----

.Kotlin
[source,kotlin,role="secondary"]
----
http {
    authorizeHttpRequests {
        shouldFilterAllDispatcherTypes = false
        authorize("/complicated/**", access(anyOf(hasRole("ADMIN"), hasAuthority("SCOPE_read"))
        // ...
        authorize(anyRequest, denyAll)
    }
}
----
====

Or you can use `WebExpressionAuthorizationManager` in the following way:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeRequests((authorize) -> authorize
        .filterSecurityInterceptorOncePerRequest(true)
        .mvcMatchers("/complicated/**").access(
			new WebExpressionAuthorizationManager("hasRole('ADMIN') || hasAuthority('SCOPE_read')")
        )
        // ...
        .anyRequest().denyAll()
    )
    // ...
----

.Kotlin
[source,kotlin,role="secondary"]
----
http {
    authorizeRequests {
        filterSecurityInterceptorOncePerRequest = true
        authorize("/complicated/**", access(
            WebExpressionAuthorizationManager("hasRole('ADMIN') || hasAuthority('SCOPE_read')"))
        )
        // ...
        authorize(anyRequest, denyAll)
    }
}
----
====

[[switch-filter-all-dispatcher-types]]
=== Switch to filter all dispatcher types

Spring Security 5.8 and earlier only xref:servlet/authorization/architecture.adoc[perform authorization] once per request.
This means that dispatcher types like `FORWARD` and `INCLUDE` that run after `REQUEST` are not secured by default.

It's recommended that Spring Security secure all dispatch types.
As such, in 6.0, Spring Security changes this default.

So, finally, change your authorization rules to filter all dispatcher types.

To do this, you should change:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeHttpRequests((authorize) -> authorize
        .shouldFilterAllDispatcherTypes(false)
        .mvcMatchers("/app/**").hasRole("APP")
        // ...
        .anyRequest().denyAll()
    )
    // ...
----

.Kotlin
[source,kotlin,role="secondary"]
----
http {
    authorizeHttpRequests {
        shouldFilterAllDispatcherTypes = false
        authorize("/app/**", hasRole("APP"))
        // ...
        authorize(anyRequest, denyAll)
    }
}
----

.Xml
[source,xml,role="secondary"]
----
<http filter-all-dispatcher-types="false" use-authorization-manager="true">
    <intercept-url pattern="/app/*" access="hasRole('APP')"/>
    <!-- ... -->
    <intercept-url pattern="/**" access="denyAll"/>
</http>
----
====

to:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeHttpRequests((authorize) -> authorize
        .shouldFilterAllDispatcherTypes(true)
        .mvcMatchers("/app/**").hasRole("APP")
        // ...
        .anyRequest().denyAll()
    )
    // ...
----

.Kotlin
[source,kotlin,role="secondary"]
----
http {
    authorizeHttpRequests {
        shouldFilterAllDispatcherTypes = true
        authorize("/app/**", hasRole("APP"))
        // ...
        authorize(anyRequest, denyAll)
    }
}
----

.Xml
[source,xml,role="secondary"]
----
<http filter-all-dispatcher-types="true" use-authorization-manager="true">
    <intercept-url pattern="/app/*" access="hasRole('APP')"/>
    <!-- ... -->
    <intercept-url pattern="/**" access="denyAll"/>
</http>
----
====

And, the `FilterChainProxy` should be registered for all dispatcher types as well.
If you are using Spring Boot, https://docs.spring.io/spring-boot/docs/current/reference/html/application-properties.html#application-properties.security.spring.security.filter.dispatcher-types[you have to change the `spring.security.filter.dispatcher-types` property] to include all dispatcher types:

====
.application.properties
[source,properties,role="primary"]
----
spring.security.filter.dispatcher-types=request,async,error,forward,include
----
====

If you are xref:servlet/configuration/java.adoc#_abstractsecuritywebapplicationinitializer[using the `AbstractSecurityWebApplicationInitializer`] you should override the `getSecurityDispatcherTypes` method and return all dispatcher types:

====
.Java
[source,java,role="primary"]
----
import org.springframework.security.web.context.*;

public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {

    @Override
    protected EnumSet<DispatcherType> getSecurityDispatcherTypes() {
        return EnumSet.of(DispatcherType.REQUEST, DispatcherType.ERROR, DispatcherType.ASYNC,
                DispatcherType.FORWARD, DispatcherType.INCLUDE);
    }

}
----
====

==== Permit `FORWARD` when using Spring MVC

If you are using {spring-framework-reference-url}/web.html#mvc-viewresolver[Spring MVC to resolve view names], you will need to permit `FORWARD` requests.
This is because when Spring MVC detects a mapping between view name and the actual views, it will perform a forward to the view.
As we saw on the <<switch-filter-all-dispatcher-types,previous section>>, Spring Security 6.0 will apply authorization to `FORWARD` requests by default.

Consider the following common configuration:

====
.Java
[source,java,role="primary"]
----
@Bean
public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
    http
        .authorizeHttpRequests((authorize) -> authorize
            .shouldFilterAllDispatcherTypes(true)
            .requestMatchers("/").authenticated()
            .anyRequest().denyAll()
        )
        .formLogin((form) -> form
            .loginPage("/login")
            .permitAll()
        ));
    return http.build();
}
----
====

and one of the following equivalents MVC view mapping configurations:

====
.Java
[source,java,role="primary"]
----
@Controller
public class MyController {

    @GetMapping("/login")
    public String login() {
        return "login";
    }

}
----
====

====
.Java
[source,java,role="primary"]
----
@Configuration
public class MyWebMvcConfigurer implements WebMvcConfigurer {

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/login").setViewName("login");
    }

}
----
====

With either configuration, when there is a request to `/login`, Spring MVC will perform a *forward* to the view `login`, which, with the default configuration, is under `src/main/resources/templates/login.html` path.
The security configuration permits requests to `/login` but every other request will be denied, including the `FORWARD` request to the view under `/templates/login.html`.

To fix this, you should configure Spring Security to permit `FORWARD` requests:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeHttpRequests((authorize) -> authorize
        .shouldFilterAllDispatcherTypes(true)
        .dispatcherTypeMatchers(DispatcherType.FORWARD).permitAll()
        .anyRequest().denyAll()
    )
    // ...
----

.Kotlin
[source,kotlin,role="secondary"]
----
http {
    authorizeHttpRequests {
        shouldFilterAllDispatcherTypes = true
        authorize(DispatcherTypeRequestMatcher(DispatcherType.FORWARD), permitAll)
        authorize(anyRequest, denyAll)
    }
}
----

.Xml
[source,xml,role="secondary"]
----
<http filter-all-dispatcher-types="true" use-authorization-manager="true">
    <intercept-url request-matcher-ref="forwardRequestMatcher" access="permitAll()" />
    <!-- ... -->
    <intercept-url pattern="/**" access="denyAll"/>
</http>

<bean name="forwardRequestMatcher" class="org.springframework.security.web.util.matcher.DispatcherTypeRequestMatcher">
    <constructor-arg value="FORWARD"/>
</bean>
----
====

=== Replace any custom filter-security ``AccessDecisionManager``s

Your application may have a custom {security-api-url}org/springframework/security/access/AccessDecisionManager.html[`AccessDecisionManager`] or {security-api-url}org/springframework/security/access/AccessDecisionVoter.html[`AccessDecisionVoter`] arrangement.
The preparation strategy will depend on your reason for each arrangement.
Read on to find the best match for your situation.

==== I use `UnanimousBased`

If your application uses {security-api-url}org/springframework/security/access/vote/UnanimousBased.html[`UnanimousBased`], you should first adapt or replace any ``AccessDecisionVoter``s and then you can construct an `AuthorizationManager` like so:

====
.Java
[source,java,role="primary"]
----
@Bean
AuthorizationManager<RequestAuthorizationContext> requestAuthorization() {
    PolicyAuthorizationManager policy = ...;
    LocalAuthorizationManager local = ...;
    return AuthorizationMangers.allOf(policy, local);
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
@Bean
fun requestAuthorization(): AuthorizationManager<RequestAuthorizationContext> {
    val policy: PolicyAuthorizationManager = ...
    val local: LocalAuthorizationManager = ...
    return AuthorizationMangers.allOf(policy, local)
}
----

.Xml
[source,xml,role="secondary"]
----
<bean id="requestAuthorization" class="org.springframework.security.authorization.AuthorizationManagers"
        factory-method="allOf">
    <constructor-arg>
        <util:list>
            <bean class="my.PolicyAuthorizationManager"/>
            <bean class="my.LocalAuthorizationManager"/>
        </util:list>
    </constructor-arg>
</bean>
----
====

then, wire it into the DSL like so:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeHttpRequests((authorize) -> authorize.anyRequest().access(requestAuthorization))
    // ...
----

.Kotlin
[source,kotlin,role="secondary"]
----
http {
    authorizeHttpRequests {
        authorize(anyRequest, requestAuthorization)
    }
    // ...
}
----

.Xml
[source,xml,role="secondary"]
----
<http authorization-manager-ref="requestAuthorization"/>
----
====

[NOTE]
====
`authorizeHttpRequests` is designed so that you can apply a custom `AuthorizationManager` to any url pattern.
See xref:servlet/authorization/authorize-http-requests.adoc#custom-authorization-manager[the reference] for more details.
====

==== I use `AffirmativeBased`

If your application uses {security-api-url}org/springframework/security/access/vote/AffirmativeBased.html[`AffirmativeBased`], then you can construct an equivalent {security-api-url}org/springframework/security/authorization/AuthorizationManager.html[`AuthorizationManager`], like so:

====
.Java
[source,java,role="primary"]
----
@Bean
AuthorizationManager<RequestAuthorizationContext> requestAuthorization() {
    PolicyAuthorizationManager policy = ...;
    LocalAuthorizationManager local = ...;
    return AuthorizationMangers.anyOf(policy, local);
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
@Bean
fun requestAuthorization(): AuthorizationManager<RequestAuthorizationContext> {
    val policy: PolicyAuthorizationManager = ...
    val local: LocalAuthorizationManager = ...
    return AuthorizationMangers.anyOf(policy, local)
}
----

.Xml
[source,xml,role="secondary"]
----
<bean id="requestAuthorization" class="org.springframework.security.authorization.AuthorizationManagers"
        factory-method="anyOf">

        <util:list>
            <bean class="my.PolicyAuthorizationManager"/>
            <bean class="my.LocalAuthorizationManager"/>
        </util:list>
    </constructor-arg>
</bean>
----
====

then, wire it into the DSL like so:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeHttpRequests((authorize) -> authorize.anyRequest().access(requestAuthorization))
    // ...
----

.Kotlin
[source,kotlin,role="secondary"]

    authorizeHttpRequests {
        authorize(anyRequest, requestAuthorization)
    }
    // ...
}
----

.Xml
[source,xml,role="secondary"]
----
<http authorization-manager-ref="requestAuthorization"/>
----
====

[NOTE]
====
`authorizeHttpRequests` is designed so that you can apply a custom `AuthorizationManager` to any url pattern.
See xref:servlet/authorization/authorize-http-requests.adoc#custom-authorization-manager[the reference] for more details.
====

==== I use `ConsensusBased`

There is no framework-provided equivalent for {security-api-url}org/springframework/security/access/vote/ConsensusBased.html[`ConsensusBased`].
In that case, please implement a composite {security-api-url}org/springframework/security/authorization/AuthorizationManager.html[`AuthorizationManager`] that takes the set of delegate ``AuthorizationManager``s into account.

Once you have implemented `AuthorizationManager`, please follow the details in the reference manual for xref:servlet/authorization/authorize-http-requests.adoc#custom-authorization-manager[adding a custom `AuthorizationManager`].

==== I use a custom `AccessDecisionVoter`

You should either change the class to implement {security-api-url}org/springframework/security/authorization/AuthorizationManager.html[`AuthorizationManager`] or create an adapter.


Without knowing what your custom voter is doing, it is impossible to recommend a general-purpose solution.
By way of example, though, here is what adapting {security-api-url}org/springframework/security/access/SecurityMetadataSource.html[`SecurityMetadataSource`] and {security-api-url}org/springframework/security/access/AccessDecisionVoter.html[`AccessDecisionVoter`] for `anyRequest().authenticated()` would look like:

====
.Java
[source,java,role="primary"]
----
public final class AnyRequestAuthenticatedAuthorizationManagerAdapter implements AuthorizationManager<RequestAuthorizationContext> {
    private final SecurityMetadataSource metadata;
    private final AccessDecisionVoter voter;

    public PreAuthorizeAuthorizationManagerAdapter(SecurityExpressionHandler expressionHandler) {
        Map<RequestMatcher, List<ConfigAttribute>> requestMap = Collections.singletonMap(
                AnyRequestMatcher.INSTANCE, Collections.singletonList(new SecurityConfig("authenticated")));
        this.metadata = new DefaultFilterInvocationSecurityMetadataSource(requestMap);
        WebExpressionVoter voter = new WebExpressionVoter();
        voter.setExpressionHandler(expressionHandler);
        this.voter = voter;
    }

    public AuthorizationDecision check(Supplier<Authentication> authentication, RequestAuthorizationContext context) {
        List<ConfigAttribute> attributes = this.metadata.getAttributes(context);
        int decision = this.voter.vote(authentication.get(), invocation, attributes);
        if (decision == ACCESS_GRANTED) {
            return new AuthorizationDecision(true);
        }
        if (decision == ACCESS_DENIED) {
            return new AuthorizationDecision(false);
        }
        return null; // abstain
    }
}
----

[[servlet-authorizationmanager-requests-opt-out]]
=== Opt-out Steps

In case you had trouble, take a look at these scenarios for optimal opt out behavior:

==== I cannot secure all dispatcher types

If you cannot secure all dispatcher types, first try and declare which dispatcher types should not require authorization like so:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeHttpRequests((authorize) -> authorize
        .shouldFilterAllDispatcherTypes(true)
        .dispatcherTypeMatchers(FORWARD, INCLUDE).permitAll()
        .mvcMatchers("/app/**").hasRole("APP")
        // ...
        .anyRequest().denyAll()
    )
    // ...
----

.Kotlin
[source,kotlin,role="secondary"]
----
http {
    authorizeHttpRequests {
        shouldFilterAllDispatcherTypes = true
        authorize(DispatcherTypeRequestMatcher(FORWARD, INCLUDE), permitAll)
        authorize("/app/**", hasRole("APP"))
        // ...
        authorize(anyRequest, denyAll)
    }
}
----

.Xml
[source,xml,role="secondary"]
----
<http filter-all-dispatcher-types="true" use-authorization-manager="true">
    <intercept-url request-matcher-ref="dispatchers"/>
    <intercept-url pattern="/app/*" access="hasRole('APP')"/>
    <!-- ... -->
    <intercept-url pattern="/**" access="denyAll"/>
</http>

<bean id="dispatchers" class="org.springframework.security.web.util.matcher.DispatcherTypeRequestMatcher">
    <constructor-arg>
        <util:list value-type="javax.servlet.DispatcherType">
            <value>FORWARD</value>
            <value>INCLUDE</value>
        </util:list>
    </constructor-arg>
</bean>
----
====

Or, if that doesn't work, then you can explicitly opt out of the behavior by setting `filter-all-dispatcher-types` and `filterAllDispatcherTypes` to `false`:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeHttpRequests((authorize) -> authorize
        .filterAllDispatcherTypes(false)
        .mvcMatchers("/app/**").hasRole("APP")
        // ...
    )
    // ...
----

.Kotlin
[source,kotlin,role="secondary"]
----
http {
    authorizeHttpRequests {
        filterAllDispatcherTypes = false
        authorize("/messages/**", hasRole("APP"))
        // ...
    }
}
----

.Xml
[source,xml,role="secondary"]
----
<http filter-all-dispatcher-types="false" use-authorization-manager="true">
    <intercept-url pattern="/app/*" access="hasRole('APP')"/>
    <!-- ... -->
</http>
----
====

or, if you are still using `authorizeRequests` or `use-authorization-manager="false"`, set `oncePerRequest` to `true`:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeRequests((authorize) -> authorize
        .filterSecurityInterceptorOncePerRequest(true)
        .mvcMatchers("/app/**").hasRole("APP")
        // ...
    )
    // ...
----

.Kotlin
[source,kotlin,role="secondary"]
----
http {
    authorizeRequests {
        filterSecurityInterceptorOncePerRequest = true
        authorize("/messages/**", hasRole("APP"))
        // ...
    }
}
----

.Xml
[source,xml,role="secondary"]
----
<http once-per-request="true" use-authorization-manager="false">
    <intercept-url pattern="/app/*" access="hasRole('APP')"/>
    <!-- ... -->
</http>
----
====

==== I cannot declare an authorization rule for all requests

If you are having trouble setting an `anyRequest` authorization rule of `denyAll`, please use {security-api-url}org/springframework/security/config/annotation/web/configurers/ExpressionUrlAuthorizationConfigurer.AuthorizedUrl.html#permitAll()[`permitAll`] instead, like so:

====
.Java
[source,java,role="primary"]
----
http
    .authorizeHttpReqeusts((authorize) -> authorize
        .mvcMatchers("/app/*").hasRole("APP")
        // ...
        .anyRequest().permitAll()
    )
----

.Kotlin
[source,kotlin,role="secondary"]
----
http {
    authorizeHttpRequests {
        authorize("/app*", hasRole("APP"))
        // ...
        authorize(anyRequest, permitAll)
    }
}
----

.Xml
[source,xml,role="secondary"]
----
<http>
    <intercept-url pattern="/app/*" access="hasRole('APP')"/>
    <!-- ... -->
    <intercept-url pattern="/**" access="permitAll"/>
</http>
----
====

==== I cannot migrate my SpEL or my `AccessDecisionManager`

If you are having trouble with SpEL, `AccessDecisionManager`, or there is some other feature that you are needing to keep using in `<http>` or `authorizeRequests`, try the following.

First, if you still need `authorizeRequests`, you are welcome to keep using it. Even though it is deprecated, it is not removed in 6.0.

Second, if you still need your custom `access-decision-manager-ref` or have some other reason to opt out of `AuthorizationManager`, do:

====
