-== OpenID Connect 1.0 Logout
-
-OpenID Connect Session Management 1.0 allows the ability to log out the end user at the Provider by using the Client.
-One of the strategies available is https://openid.net/specs/openid-connect-rpinitiated-1_0.html[RP-Initiated Logout].
-
-If the OpenID Provider supports both Session Management and https://openid.net/specs/openid-connect-discovery-1_0.html[Discovery], the client can obtain the `end_session_endpoint` `URL` from the OpenID Provider's https://openid.net/specs/openid-connect-session-1_0.html#OPMetadata[Discovery Metadata].
-You can do so by configuring the `ClientRegistration` with the `issuer-uri`, as follows:
-
-[source,yaml]

-  security:
-    oauth2:
-      client:
-        registration:
