Following QV11SR2 installation, no user can go pass the AccessPoint. User gets "Login failed". Note that the DSC is up and running, all designated users have an assigned CAL and I'm able to lookup users in the Users tab without a problem.
We had changed this setting during installation, back when QV 11 IR came out and it worked through all updates until the Update to SR2. Maybe something (authentication?) on the "alternate login page" - webpage has been changed and is not working anymore?
