On a small internal LAN I have a server set up for NIS password/groups and NFS to export /home. On client machines I have confirmed that NIS is working and that /home is mounted from the server. I'm running Core 1 with all the latest updates on each machine. Users have accounts on the server, not on the clients. I have tried both gdm and kdm, but am unable to get a user login. Failsafe logins work. It appears that in the PostLogin/PreSession part of the X setup gdm wants to write some configuration information in the users home directory, but doesn't have permission, i.e. for gnome it wants to write to the user's .gnome2_private directory. I'm guessing that the script is running under the gdm user id, so naturally doesn't have the required write permission. Have I missed some configuration option? I found a few references in the archives from others who reported this problem, but never saw any solutions posted. This seems to be such a widely used method that there must be an easy way to do it, but I'm stumped and would appreciate any help or suggestions you can give.
