Admin members receiving login prompt
I am receiving a login prompt when accessing the portal with my admin account. Supplying credentials is not allowing the login. This is for my test environment, so it's not urgent, but the last change I made was installing the portal update to 11.2.2. I've never had anything like that happen after installations, so I'm thinking this is not the reason, it's just the most recent change I know of. Anyone in our admin group is receiving the prompt, but accounts in our analyst group can access the portal just fine.
I checked that the SCSM AD connector is working and the group and users are in the CI database. IIS appears to mirror my production environment. No errors in the cache builder log. Tried it across multiple browsers. Any ideas?
