I am unable to log into wikitech, it claims "Incorrect username or password entered". Same with Horizon. I can log in via password reset, but then the new password does not work either. It doesn't work for reauthentication (e.g. before getting access to Special:ChangePassword) either.
In other words, TemporaryPasswordPrimaryAuthenticationProvider works but the LDAP auth provider is screwed up.
My LDAP username is (or was) Gergő Tisza.
