So my RP uses WS-Fed and the IdP uses SAMLp and to allow the two to communicate, I'm using ADFS 2.0. The problem I'm having is that the IdP does not have an SAML Logout endpoint but instead has an html page to which I'm to redirect the user after killing the local session. ADFS expects an SLO endpoint to handle the SAMLRequest but I have none to provide and it errors stating it could not complete the logout properly. How can I tell ADFS to initiate a logout, so it clears its cookies and whatnot, without it's desire to redirect to the IdP? I need it to do a local logout, redirect back to the RP, and then I handle the rest. Should I add another page to ADFS that is essentially a hard coded cookie killer? I don't really like that kind of approach. What can I do?
Thank you for the help! Eric
