Bug#703622: gdm3 dosen't show login screen when authentication via LDAP is enabled

[Mgr. Peter Tuharsky]

Package: gdm3
Version: 3.4.1-6
Severity: important

Hallo,

I have installed Debian Wheezy RC1 x64 and while authenticating locally, GDM3 worked fine. As soon as I switched to LDAP-based authentication, GDM3 dosen't even display login screen, only clocked cursor on blank black background. I also tried applying config files that worked well with Squeeze, with no effect. Login from shell and SSH works fine. Eventually I have installed lightdm and it works well. Therefore I assume this is GDM3 related bug.
