In our project, It is required to logout SAML during Server Timeout (ASP Session Timeout). The first thing I tried is doing SAMLServiceProvider.InitiateSLO but upon this time of the call, SSO Information is no longer available. And then I tried doing the SAMLServiceProvider.InitiateSLO during Session_End before the ASP Session is gone, but the problem with this part is there is no available context already (null). I tried creating a dummy context but it also doesnt work and IDP doesnt respond from the request. We are using InProc and we really need to logout SAML on Server Timeout, Is there any way to do this?
