The home directories are mounted under /home/<user>. I don't use autofs 
for that since I had problems with that a long time ago. So all 
workstations have a /home mounted with NFS.

I actually have problems that passwords don't get updated. I noticed 
that by changing the home directory in /etc/passwd. When I change that 
from /home/user to /nobackup/home/user it does work with ypcat passwd (I 
see the correct path on the client). When I do cd ~user however, it 
still tries to look in /home/user instead of /nobackup/home/user. I need 
to restart ypserv to get this change to propagate to the workstations. 
That explains why a user could not log on after I reset his password and 
did a "make -C /var/yp".
