If you are currently using ApacheDS as an embedded LDAP server, we recommend migrating to https://ldap.com/unboundid-ldap-sdk-for-java/[UnboundId].
You can find instructions in xref:servlet/authentication/passwords/ldap.adoc#servlet-authentication-ldap-embedded[this section] that describe how to set up an embedded UnboundId LDAP server.
To migrate, you will need to consider the following:
1. <<ldap-migrate-apacheds-unboundid-dependencies,Dependencies>>
2. <<ldap-migrate-apacheds-unboundid-container,Container Declaration>>
3. <<ldap-migrate-apacheds-unboundid-password-encoding,Password Encoding>>
4. <<ldap-migrate-apacheds-unboundid-password-encoding,Password Hiding>>
[[ldap-migrate-apacheds-unboundid-dependencies]]
=== Switch Your Dependencies
To use UnboundID, you will at least need to remove the ApacheDS dependencies:
[tabs]
======
Maven::
+
[source,maven,role="primary"]
----
<dependency>
<groupId>org.apache.directory.server</groupId>
<artifactId>apacheds-core</artifactId>
<version>1.5.5</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.apache.directory.server</groupId>
<artifactId>apacheds-server-jndi</artifactId>
<version>1.5.5</version>
<scope>runtime</scope>
</dependency>
----
Gradle::
+
[source,gradkle,role="secondary"]
----
implementation("org.apache.directory.server:apacheds-server-jndi")
implementation("org.apache.directory.server:apacheds-core")
----
======
and replace them with UnboundID:
[tabs]
======
Maven::
+
[source,maven,role="primary"]
----
<dependency>
<groupId>com.unboundid</groupId>
<artifactId>unboundid-ldapsdk</artifactId>
<version>7.0.3</version>
<scope>runtime</scope>
</dependency>
----
Gradle::
+
[source,gradkle,role="secondary"]
----
implementation("org.apache.directory.server:apacheds-server-jndi")
implementation("org.apache.directory.server:apacheds-core")
----
======
If you are accepting the LDAP server defaults, this is likely all you will need to do.
[[ldap-migrate-apacheds-unboundid-container]]
=== Change Server Declaration
If you are declaring an ApacheDS server, then you will need to change its declaration.
Your configuration may vary somewhat from the following.
Change this:
[tabs]
======
Java::
+
[source,java,role="primary"]
----
@Bean
EmbeddedLdapServerContainer ldapContainer() {
EmbeddedLdapServerContainer container =
new ApacheDSContainer("dc=springframework,dc=org", "classpath:test-server.ldif");
container.setPort(0);
return container;
}
----
Kotlin::
+
[source,kotlin,role="secondary"]
----
@Bean
fun ldapContainer(): EmbeddedLdapServerContainer {
val container =
ApacheDSContainer("dc=springframework,dc=org", "classpath:test-server.ldif")
container.setPort(0)
return container
}
----
Xml::
+
[source,xml,role="secondary"]
----
<ldap-server mode="apacheds"/>
----
======
to this:
[tabs]
======
Java::
+
[source,java,role="primary"]
----
@Bean
EmbeddedLdapServerContainer ldapContainer() {
EmbeddedLdapServerContainer container =
new UnboundIdContainer("dc=springframework,dc=org", "classpath:test-server.ldif");
container.setPort(0);
return container;
}
----
Kotlin::
+
[source,kotlin,role="secondary"]
----
@Bean
fun ldapContainer(): EmbeddedLdapServerContainer {
val container =
UnboundIdContainer("dc=springframework,dc=org", "classpath:test-server.ldif")
container.setPort(0)
return container
}
----
Xml::
+
[source,xml,role="secondary"]
----
<ldap-server mode="unboundid"/>
----
======
[[ldap-migrate-apacheds-unboundid-password-encoding]]
=== Configure Password Encoding
Apache Directory Server supports binding with SHA-hashed passwords, but UnboundID does not.
If you run into trouble with binding users with SHA-hashed passwords, move to Spring Security's `PasswordComparisonAuthenticator` by providing a password encoder to the authentication provider:
[tabs]
======
Java::
+
[source,java,role="primary"]
----
@Bean
AuthenticationManager ldapAuthenticationManager(BaseLdapPathContextSource contextSource) {
LdapPasswordComparisonAuthenticationManagerFactory factory =
new LdapPasswordComparisonAuthenticationManagerFactory(
contextSource, new LdapShaPasswordEncoder());
// ...
return factory.createAuthenticationManager();
}
----
Kotlin::
+
[source,kotlin,role="secondary"]
----
@Bean
fun ldapAuthenticationManager(val contextSource: BaseLdapPathContextSource): AuthenticationManager {
val factory = LdapPasswordComparisonAuthenticationManagerFactory(
contextSource, LdapShaPasswordEncoder())
// ...
return factory.createAuthenticationManager()
}
----
Xml::
+
[source,xml,role="secondary"]
----
<auhentication-manager>
<ldap-authentication-provider>
<password-compare>
<password-encoder ref='pe' />
</password-compare>
</ldap-authentication-provider>
</auhentication-manager>
<b:bean id='pe' class='org.springframework.security.crypto.password.LdapShaPasswordEncoder' />
----
======
[WARN]
====
Hashing passwords with `+{SHA}+` is not recommended.
Please migrate to BCrypt, SCrypt, or Argon2 as soon as possible.
You can use the same approach above to provide the corresponding password encoder.
====
[[ldap-migrate-apacheds-unboundid-password-hiding]]
=== Configure Password Hiding
ApacheDS is configured by Spring Security to hide the `userPassword` attribute from search results unless explicitly queried.
UnboundID does not support this.
You can achieve this behavior with a custom `InMemoryOperationInterceptor` like the following:
[source,java]
----
static class PasswordRemovingOperationInterceptor
extends InMemoryOperationInterceptor {
@Override
public void processSearchEntry(InMemoryInterceptedSearchEntry entry) {
if (!entry.getRequest().getAttributeList().contains("userPassword")) {
if (entry.getSearchEntry().getAttribute("userPassword") != null) {
Entry old = entry.getSearchEntry();
Collection<Attribute> attributes = old.getAttributes().stream()
.filter(attribute ->
!"userPassword".equals(attribute.getName()))
.collect(Collectors.toList());
Entry withoutPassword = new Entry(old.getDN(), attributes);
entry.setSearchEntry(withoutPassword);
}
}
}
}
----
[NOTE]
====
It is better to secure passwords by hashing them and by using queries that identify the specific columns that you need.
====
`UnboundIdContainer` does not currently have a way to register a custom `InMemoryOperationInterceptor`, but you can either copy the contents of `UnboundIdContainer` or use Spring LDAP Test's `EmbeddedLdapServer` builder in order to provide this interceptor and confirm your application's readiness.
