= Performing Single Logout
|
|
|
|
Among its xref:servlet/authentication/logout.adoc[other logout mechanisms], Spring Security ships with support for RP- and AP-initiated SAML 2.0 Single Logout.
|
|
|
|
Briefly, there are two use cases Spring Security supports:
|
|
|
|
* **RP-Initiated** - Your application has an endpoint that, when POSTed to, will logout the user and send a `saml2:LogoutRequest` to the asserting party.
|
|
Thereafter, the asserting party will send back a `saml2:LogoutResponse` and allow your application to respond
|
|
* **AP-Initiated** - Your application has an endpoint that will receive a `saml2:LogoutRequest` from the asserting party.
|
|
Your application will complete its logout at that point and then send a `saml2:LogoutResponse` to the asserting party.
|
|
|
|
[NOTE]
|
|
In the **AP-Initiated** scenario, any local redirection that your application would do post-logout is rendered moot.
|
|
Once your application sends a `saml2:LogoutResponse`, it no longer has control of the browser.
|
|
|
|
== Minimal Configuration for Single Logout
|
|
|
|
To use Spring Security's SAML 2.0 Single Logout feature, you will need the following things:
|
|
|
|
* First, the asserting party must support SAML 2.0 Single Logout
|
|
* Second, the asserting party should be configured to sign and POST `saml2:LogoutRequest` s and `saml2:LogoutResponse` s your application's `/logout/saml2/slo` endpoint
|
|
* Third, your application must have a PKCS#8 private key and X.509 certificate for signing `saml2:LogoutRequest` s and `saml2:LogoutResponse` s
|
|
|
|
You can achieve this in Spring Boot in the following way:
|
|
|
|
[source,yaml]

|
|
<2> - The SLO endpoint in your application
|
|
<3> - The signing credentials to sign ``<saml2:LogoutRequest>``s and ``<saml2:LogoutResponse>``s
|
|
|
|
[NOTE]
|
|
----
|
|
An asserting party supports Single Logout if their metadata includes the `<SingleLogoutService>` element in their metadata.
|
|
----
|
|
|
|
And that's it!
|
|
|
|
Spring Security's logout support offers a number of configuration points.
|
|
Consider the following use cases:
|
|
|
|
* Understand how the above <<_startup_expectations, minimal configuration works>>
|
|
* Get a picture of <<architecture, the overall architecture>>
|
|
* Allow users to <<separating-local-saml2-logout, logout out of the app only>>
|
|
* Customize <<_configuring_logout_endpoints, logout endpoints>>
|
|
* Storing `<saml2:LogoutRequests>` somewhere <<_customizing_storage, other than the session>>
|
|
|
|
=== Startup Expectations
|
|
|
|
When these properties are used, in addition to login, SAML 2.0 Service Provider will automatically configure itself facilitate logout by way of ``<saml2:LogoutRequest>``s and ``<saml2:LogoutResponse>``s using either RP- or AP-initiated logout.
|
|
|
|
It achieves this through a deterministic startup process:
|
|
|
|
1. Query the Identity Server Metadata endpoint for the `<SingleLogoutService>` element
|
|
2. Scan the metadata and cache any public signature verification keys
|
|
3. Prepare the appropriate endpoints
|
|
|
|
A consequence of this process is that the identity server must be up and receiving requests in order for Service Provider to successfully start up.
|
|
|
|
[NOTE]
|
|
If the identity server is down when Service Provider queries it (given appropriate timeouts), then startup will fail.
|
|
|
|
=== Runtime Expectations
|
|
|
|
Given the above configuration any logged-in user can send a `POST /logout` to your application to perform RP-initiated SLO.
|
|
Your application will then do the following:
|
|
|
|
1. Logout the user and invalidate the session
|
|
2. Produce a `<saml2:LogoutRequest>` and POST it to the associated asserting party's SLO endpoint
|
|
3. Then, if the asserting party responds with a `<saml2:LogoutResponse>`, the application with verify it and redirect to the configured success endpoint
|
|
|
|
Also, your application can participate in an AP-initiated logout when the asserting party sends a `<saml2:LogoutRequest>` to `/logout/saml2/slo`.
|
|
When this happens, your application will do the following:
|
|
|
|
1. Verify the `<saml2:LogoutRequest>`
|
|
2. Logout the user and invalidate the session
|
|
3. Produce a `<saml2:LogoutResponse>` and POST it back to the asserting party's SLO endpoint
|
|
|
|
== Minimal Configuration Sans Boot
|
|
|
|
Instead of Boot properties, you can also achieve the same outcome by publishing the beans directly like so:

[NOTE]

Adding `saml2Logout` adds the capability for logout to your service provider as a whole.
|
|
Because it is an optional capability, you need to enable it for each individual `RelyingPartyRegistration`.
|
|
You do this by setting the `RelyingPartyRegistration.Builder#singleLogoutServiceLocation` property as seen above.

[[architecture]]
|
|
== How Saml 2.0 Logout Works
|
|
|
|
Next, let's see the architectural components that Spring Security uses to support https://docs.oasis-open.org/security/saml/v2.0/saml-profiles-2.0-os.pdf#page=37[SAML 2.0 Logout] in servlet-based applications, like the one we just saw.
|
|
|
|
For RP-initiated logout:
|
|
|
|
image:{icondir}/number_1.png[] Spring Security executes its xref:servlet/authentication/logout.adoc#logout-architecture[logout flow], calling its ``LogoutHandler``s to invalidate the session and perform other cleanup.
|
|
It then invokes the {security-api-url}org/springframework/security/saml2/provider/service/web/authentication/logout/Saml2RelyingPartyInitiatedLogoutSuccessHandler.html[`Saml2RelyingPartyInitiatedLogoutSuccessHandler`].
|
|
|
|
image:{icondir}/number_2.png[] The logout success handler uses an instance of
|
|
{security-api-url}org/springframework/security/saml2/provider/service/web/authentication/logout/Saml2LogoutRequestResolver.html[`Saml2LogoutRequestResolver`] to create, sign, and serialize a `<saml2:LogoutRequest>`.
|
|
It uses the keys and configuration from the xref:servlet/saml2/login/overview.adoc#servlet-saml2login-relyingpartyregistration[`RelyingPartyRegistration`] that is associated with the current `Saml2AuthenticatedPrincipal`.
|
|
Then, it redirect-POSTs the `<saml2:LogoutRequest>` to the asserting party SLO endpoint
|
|
|
|
The browser hands control over to the asserting party.
|
|
If the asserting party redirects back (which it may not), then the application proceeds to step image:{icondir}/number_3.png[].
|
|
|
|
image:{icondir}/number_3.png[] The {security-api-url}org/springframework/security/saml2/provider/service/web/authentication/logout/Saml2LogoutResponseFilter.html[`Saml2LogoutResponseFilter`] deserializes, verifies, and processes the `<saml2:LogoutResponse>` with its {security-api-url}org/springframework/security/saml2/provider/service/authentication/logout/Saml2LogoutResponseValidator.html[`Saml2LogoutResponseValidator`].
|
|
|
|
image:{icondir}/number_4.png[] If valid, then it completes the local logout flow by redirecting to `/login?logout`, or whatever has been configured.
|
|
If invalid, then it responds with a 400.
|
|
|
|
For AP-initiated logout:
|
|
|
|
image:{icondir}/number_1.png[] The {security-api-url}org/springframework/security/saml2/provider/service/web/authentication/logout/Saml2LogoutRequestFilter.html[`Saml2LogoutRequestFilter`] deserializes, verifies, and processes the `<saml2:LogoutRequest>` with its {security-api-url}org/springframework/security/saml2/provider/service/authentication/logout/Saml2LogoutRequestValidator.html[`Saml2LogoutRequestValidator`].
|
|
|
|
image:{icondir}/number_2.png[] If valid, then the filter calls the configured ``LogoutHandler``s, invalidating the session and performing other cleanup.
|
|
|
|
image:{icondir}/number_3.png[] It uses a {security-api-url}org/springframework/security/saml2/provider/service/web/authentication/logout/Saml2LogoutResponseResolver.html[`Saml2LogoutResponseResolver`] to create, sign and serialize a `<saml2:LogoutResponse>`.
|
|
It uses the keys and configuration from the xref:servlet/saml2/login/overview.adoc#servlet-saml2login-relyingpartyregistration[`RelyingPartyRegistration`] derived from the endpoint or from the contents of the `<saml2:LogoutRequest>`.
|
|
Then, it redirect-POSTs the `<saml2:LogoutResponse>` to the asserting party SLO endpoint.
|
|
|
|
The browser hands control over to the asserting party.
|
|
|
|
image:{icondir}/number_4.png[] If invalid, then it https://github.com/spring-projects/spring-security/pull/14676[responds with a 400].
|
|
|
|
== Configuring Logout Endpoints
|
|
|
|
There are three behaviors that can be triggered by different endpoints:
|
|
|
|
* RP-initiated logout, which allows an authenticated user to `POST` and trigger the logout process by sending the asserting party a `<saml2:LogoutRequest>`
|
|
* AP-initiated logout, which allows an asserting party to send a `<saml2:LogoutRequest>` to the application
|
|
* AP logout response, which allows an asserting party to send a `<saml2:LogoutResponse>` in response to the RP-initiated `<saml2:LogoutRequest>`
|
|
|
|
The first is triggered by performing normal `POST /logout` when the principal is of type `Saml2AuthenticatedPrincipal`.
|
|
|
|
The second is triggered by POSTing to the `/logout/saml2/slo` endpoint with a `SAMLRequest` signed by the asserting party.
|
|
|
|
The third is triggered by POSTing to the `/logout/saml2/slo` endpoint with a `SAMLResponse` signed by the asserting party.
|
|
|
|
Because the user is already logged in or the original Logout Request is known, the `registrationId` is already known.
|
|
For this reason, `+{registrationId}+` is not part of these URLs by default.
|
|
|
|
This URL is customizable in the DSL.
|
|
|
|
For example, if you are migrating your existing relying party over to Spring Security, your asserting party may already be pointing to `GET /SLOService.saml2`.
|
|
To reduce changes in configuration for the asserting party, you can configure the filter in the DSL like so:

logoutUrl = "/SLOService.saml2"
|
|
}
|
|
}
|
|
}
|
|
----
|
|
======
|
|
|
|
You should also configure these endpoints in your `RelyingPartyRegistration`.
|
|
|
|
Also, you can customize the endpoint for triggering logout locally like so:

=== Separating Local Logout from SAML 2.0 Logout
|
|
|
|
In some cases, you may want to expose one logout endpoint for local logout and another for RP-initiated SLO.
|
|
Like is the case with other logout mechanisms, you can register more than one, so long as they each have a different endpoint.
|
|
|
|
So, for example, you can wire the DSL like so:
|
|
|
|
[tabs]
|
|

|
|
Java::
|
|
+
|
|
[source,java,role="primary"]
|
|
----
|
|
http
|
|
.logout((logout) -> logout.logoutUrl("/logout"))
|
|
.saml2Logout((saml2) -> saml2.logoutUrl("/saml2/logout"));
|
|
----
|

|
|
Kotlin::

http {
|
|
logout {
|
|
logoutUrl = "/logout"
|
|
}
|
|
saml2Logout {
|
|
logoutUrl = "/saml2/logout"
|
|
}
|
|
}
|
|
----
|
|
======
|
|
|
|
and now if a client sends a `POST /logout`, the session will be cleared, but there won't be a `<saml2:LogoutRequest>` sent to the asserting party.
|
|
But, if the client sends a `POST /saml2/logout`, then the application will initiate SAML 2.0 SLO as normal.
|
|
|
|
== Customizing `<saml2:LogoutRequest>` Resolution
|
|
|
|
It's common to need to set other values in the `<saml2:LogoutRequest>` than the defaults that Spring Security provides.
|
|
|
|
By default, Spring Security will issue a `<saml2:LogoutRequest>` and supply:
|
|
|
|
* The `Destination` attribute - from `RelyingPartyRegistration#getAssertingPartyDetails#getSingleLogoutServiceLocation`
|
|
* The `ID` attribute - a GUID
|
|
* The `<Issuer>` element - from `RelyingPartyRegistration#getEntityId`
|
|
* The `<NameID>` element - from `Authentication#getName`
|
|
|
|
To add other values, you can use delegation, like so:

To customize validation, you can implement your own `Saml2LogoutRequestValidator`.

At this point, the validation is minimal, so you may be able to first delegate to the default `Saml2LogoutRequestValidator` like so:

== Customizing `<saml2:LogoutRequest>` storage
|
|
|
|
When your application sends a `<saml2:LogoutRequest>`, the value is stored in the session so that the `RelayState` parameter and the `InResponseTo` attribute in the `<saml2:LogoutResponse>` can be verified.
|
|
|
|
If you want to store logout requests in some place other than the session, you can supply your custom implementation in the DSL, like so:
|
|
|
|
[tabs]
