Comment 27 for bug 1003296

Actually, this is not the first time we see a similar issue. We ran into it with 10.04 / Lucid + samba + gdm and this was before our domain controllers were 2008 R2. I can't quite remeber what fixed it then (I'm still digging through old emails) but I have a vague memory of it being fixed by a samba / winbind patch.
