I am using (trying to anyway) an ActiveDirectory plugin for ScrewTurn wiki called UserAuth (by "ElectricImages"). Whenever a user logs into the Wiki's login page with correct network credentials (provides domain\user and password), they get a login error and the ScrewTurn log shows the message Authentication of ...... failed: A referral was returned from the server.
If the user gives the wrong password, then the log says Authentication of ...... failed: Logon failure: unknown user name or bad password, so it seems that ActiveDirectory is in fact getting the authentication info.
What could be going wrong?
