Not a special user or login as special user is not allowed

I'm trying to migrate our users over to Azure AD, the 3 users migrated over fine and were able to login with azure, but now we are seeing an error displayed to the users.

In the logs I'm seeing:

[2016-03-16 15:14:29,375]   INFO [66:64972; http-bio-443-exec-49] - Login for user "<redacted email address>" failed for module "jetbrains.buildServer.serverSide.impl.auth.SpecialUsersLoginModule": jetbrains.buildServer.serverSide.auth.TeamCityFailedLoginException: Not a special user or login as special user is not allowed.

Nothing else stands out in the logs. Where else can I look to find out what might be causing the failed logins.

Ah, I've also found this:
