New issue 914: Session 5 - Missing client_id parameter
https://bitbucket.org/openid/connect/issue/914/session-5-missing-client_id-parameter

lainhart:

Should the post_logout_redirect_uri parameter be provided to the end_session_endpoint, the OP needs to verify that the URI was previously registered to the requesting RP.  A client_id is required to make that verification.  Is the assumption that the OP will get this value from the id_token_hint?  If true, that value is "recommended".  Should the client_id be an explicit parameter?  That's how I've currently got it implemented.
