    How about error code 0xCAA900023; state 10"Could not discover endpoint for username/password authentication. Check your ADFS settings. It should support username/password authentication for WS-Trust 1.3 or WS-Trust 2005."Our ADFS 2.0 has both windowstransport endpoints enabled and it still does not work.
