Problems with ldap authentication (gdm)

[Dimitrie O. Paun]

It looks like there is (again?) an authentication problem with gdm.

Namely, when I'm trying to use LDAP authentication, both
local login on a regular console and slogin work like a charm,
but gdm fails with the error:
  "cannot set your user group, you will not be able to log in, please contact your system administrator"

Now, this is what I get in /var/log/messages:

Jan 12 01:03:16 saturn gdm[2847]: Cannot set user group for bugger
Jan 12 01:03:53 saturn gdm[2847]: Cannot set user group for bugger

I've done my homework, but I can't seem to find anything useful.
Now, I did find a _very_ similar bug reported (strangely enough)
exactly one year ago:
    http://www.redhat.com/archives/fedora-devel-list/2004-January/msg00726.html
but that didn't help much either.

Any hints would be much appreciated!
