I moved the topic over the standards center space and added a draft header for now.</p> <p style="margin: 10px 0 0 0">I wish I had a better idea about the logout problem but I guess that's the simplest choice. We could just mint a urn:mace:shibboleth value to use as a placeholder for that location, and not worry about enforcing it being there of course. Whatever we do I'd rather we define a value to go there as the "previous location" indicator.</p> <p style="margin: 10px 0 0 0">Returning to the proxy issue, my understanding of that flow is such that I still think I would suggest just using SPSSODescriptor for that. Neither AssertionConsumerService nor AttributeService are good "fits" for that validation endpoint so that's not really an argument in favor of the AA role.</p> <p style="margin: 10px 0 0 0">The proxy flow as I understand it is just a delegated SP, a service that authenticates as the original ticketed user to another service. So I would just use SPSSODescriptor and define a Binding string to use for the ACS endpoint that acts as that validation point you want to use.</p> <p style="margin: 10px 0 0 0">The other point I would make is about the certificates. Unlike SAML, there's not going to be signed messages here, so that means you're really suggesting the web server's browser-facing TLS certificate is in the metadata. That works, obviously, but the reason we've always avoided doing that is because of the forcible key rollover that causes. Obviously you <b>could</b> setup a separate port and key for that like we used to do with SAML/SOAP, but we don't advocate for that anymore, and I don't think we would ever expect an SP to run that way.</p> <p style="margin: 10px 0 0 0">So that's more of a "be careful of the implications of doing this" comment. It's entirely correct, it just has some downsides. But I suppose CAS being more internal to enterprises, I could imagine that the key rollover could be more gracefully managed with metadata than your average SAML federation deployment.</p> </td>
