Does ADFS 2.0 supports the SAML 1.1 protocol and Web SSO profiles as mentionend in this Wikipedia article or are only SAML 1.1 tokens supported?
A SAML 2.0 identity provider (IDP) can take many forms, one of which is a self-hosted Active Directory Federation Services (ADFS) server. ADFS is a service provided by Microsoft as a standard role for Windows Server that provides a web login using existing Active Directory credentials.
ADFS uses a claims-based access-control authorization model. This process involves authenticating users via cookies and Security Assertion Markup Language (SAML). That means ADFS is a type of Security Token Service, or STS.
AD FS supports the WS-Trust, WS-Federation (WS-Fed) and SAML 2.0 Web SSO protocols for relying parties.
According to my research ADFS 2.0 supports WS-Federation and the SAML 2.0 protocol (SAML-P). SAML 1.1 is only supported as a token format. This makes sense as WS-Federation supports various token formats including SAML 2.0 and SAML 1.1. So there is SAML 1.1 support because of the token issue...
