Possible approach to handle OIDC logout consent denial by the end-user

Hi Piraveena,

If RP not sending the *post_logout_redirect_uri* or its not matched with
the OP registered *post_logout_redirect_uris, *(regardless of user denied
the consent or approved) user would be redirected to some page in OP.

If the post_logout_redirect_uri is available and valid, IMO the better
behaviour would be redirecting to the *post_logout_redirect_uri*. Here,
user will be only logged out from the RP, but not the OP.

PS: Saw the Thomas's reply halfway through, but continued sending this one.
:)

Thanks,
