+     * Configures logout support for a SAML 2.0 Service Provider. <br>
+     * <br>
+     *
+     * Implements the <b>Single Logout Profile, using POST and REDIRECT bindings</b>, as
+     * documented in the
+     * <a target="_blank" href="https://docs.oasis-open.org/security/saml/">SAML V2.0
+     * Core, Profiles and Bindings</a> specifications. <br>
+     * <br>
+     *
+     * As a prerequisite to using this feature, is that you have a SAML v2.0 Asserting
+     * Party to send a logout request to. The representation of the relying party and the
+     * asserting party is contained within [RelyingPartyRegistration]. <br>
+     * <br>
+     *
+     * [RelyingPartyRegistration] (s) are composed within a
+     * [RelyingPartyRegistrationRepository], which is <b>required</b> and must be
+     * registered with the [ApplicationContext] or configured via
+     * [HttpSecurityDsl.saml2Login].<br>
+     * <br>
+     *
+     * The default configuration provides an auto-generated logout endpoint at
+     * `/logout` and redirects to `/login?logout` when
+     * logout completes. <br>
+     * <br>
+     *
+     * <p>
+     * <h2>Example Configuration</h2>
+     *
+     * The following example shows the minimal configuration required, using a
+     * hypothetical asserting party.
+     *
+     * Example:
+     *
+     * ```
+     * @Configuration
+     * @EnableWebSecurity
+     * class SecurityConfig {
+     *
+     *     @Bean
+     *     fun securityFilterChain(http: HttpSecurity): SecurityFilterChain {

+     *         return http.build()
+     *     }
+     * }
