.Xauthority in NFS/NIS-Environments - X-Forwarding doesn't work

Hello there,

we have here a few openSUSE-machines (some 11.1 and 11.2) which mounts their /home from a NFS-Server and imports the users via NIS.

I now wanted to use X-Forwarding via SSH, but that doesn’t work with NIS-Users.
On my machine I use Gnome and my XAUTHORITY-Variable points to
/var/run/gdm/auth-for-bup_deg-E3TMSz/database

Why isn’t the default ~/.Xauthority-File used for my cookies? What do I have to change to get X-Forwarding in my Setup running?

Dieter

Any Ideas?
I don’t understand why the XAUTHORITY-Variable in newer distributions point to /var/run… does that makes any sense?
