This commit separates the authentication principal, the assertion details, and the relying party tenant into separate components. This allows the principal to be completely decoupled from how Spring Security triggers and processes SLO. Specifically, it adds Saml2AssertionAuthentication, a new authentication implementation that allows an Object principal and a Saml2ResponseAssertionAccessor credential. It also moves the relying party registration id from Saml2AuthenticatedPrincipal to Saml2AssertionAuthentication. As such, Saml2AuthenticatedPrincipal is now deprecated in favor of placing its assertion components in Saml2ResponseAssertionAccessor and the relying party registration id in Saml2AssertionAuthentication. Closes gh-10820

Extensive JavaDoc for the Spring Security code is also available in the https://docs.spring.io/spring-security/site/docs/current/api/[Spring Security API Documentation]. You may also want to check out https://docs.spring.io/spring-security/reference/whats-new.html[what's new in the latest release]. == Quick Start See https://docs.spring.io/spring-security/reference/servlet/getting-started.html[Hello Spring Security] to get started with a "Hello, World" application. == Building from Source Spring Security uses a https://gradle.org[Gradle]-based build system. In the instructions below, https://vimeo.com/34436402[`./gradlew`] is invoked from the root of the source tree and serves as a cross-platform, self-contained bootstrap mechanism for the build. === Prerequisites https://docs.github.com/en/get-started/quickstart/set-up-git[Git] and the https://www.oracle.com/java/technologies/downloads/#java17[JDK17 build]. Be sure that your `JAVA_HOME` environment variable points to the `jdk-17` folder extracted from the JDK download. === Check out sources [indent=0] ---- git clone git@github.com:spring-projects/spring-security.git ---- === Install all `spring-*.jar` into your local Maven repository.
