Currently have a deployment of ADFS 2.0 with a WIF web application. WIF application is configured in ADFS 2.0 as a Reply Party. Multiple Claim Providers are also configured within ADFS 2.0. For SP-initiated, end-user request WIF application, redirected over to ADFS 2.0 system for home-realm discovery, redirected to Claims Provider configured IdP, authentication is performed, redirect back to ADFS with POST of SAMLResponse and then final redirect back to WIF application with FedAuth security token. This is working perfectly.
What I'm trying to understand is how can ADFS 2.0/WIF application be configured to consume a SAMLResponse token when end-user authentication begins with customer IdP. So the first request our ADFS 2.0/WIF application would see is HTTP POST containing SAMLResponse token. Should this be POST'd to https://../adfs/ls/ or to the WIF application? Would the new WIF extension for SAML 2.0 CTP be required and WIF application developed to consume SAMLResponse?
Any help is greatly appreciated. Thanks.
