An OpenId client (Relying Party, or "RP") can notify the OP that the End-User has logged out of the site and might want to log out of the OP as well. In this case, the RP, after having logged the End-User out of the RP, redirects the End-User's User Agent to the OP's logout endpoint URL. This URL is normally obtained via the end_session_endpoint element of the OP's Discovery response or may be learned via other mechanisms.
This specification also defines the following parameters that are passed as query parameters in the logout request:
id-token-hint | RECOMMENDED | Previously issued ID Token passed to the logout endpoint as a hint about the End-User's current authenticated session with the Client. This is used as an indication of the identity of the End-User that the RP is requesting be logged out by the OP. The OP need not be listed as an audience of the ID Token when it is used as an id_token_hint value. |
post-logout-redirect-uri | OPTIONAL | URL to which the RP is requesting that the End-User's User Agent be redirected after a logout has been performed. The value MUST have been previously registered with the OP, either using the post_logout_redirect_uris Registration parameter or via another mechanism. If supplied, the OP SHOULD honor this request following the logout. |
state | OPTIONAL | Opaque value used by the RP to maintain state between the logout request and the callback to the endpoint specified by the post_logout_redirect_uri query parameter. If included in the logout request, the OP passes this value back to the RP using the state query parameter when redirecting the User Agent back to the RP. |
At the logout endpoint, the OP SHOULD ask the End-User whether he wants to log out of the OP as well. If the End-User says "yes", then the OP MUST log out the End-User.
Client-initiated logout (non-standard)
If the end session request is cryptographically verified by the OP then the End User is automatically and immediately logged out of the Client session. This is a non-standard feature implemented on Key Bridge systems.
