<p class="MsoNormal">One flow could be having a RP go to a web page and do a manual registration, then plug in their client_id, client_secret, return_to, and Idp client registration endpoint into their software and have it do a refresh to get the other parameters.<o:p></o:p></p>

<p class="MsoNormal">I suspect that the Client Registration endpoint will need to also be the issuer_id. Without introducing a post authentication discovery step we need to map the signature on the session token back to a shared secret (or public key) If
we allow the other endpoints to be on other domains potentially, that leaves the registration one as the likely choice.<o:p></o:p></p>
