NFS on SuSE6.3

I know it is a bit off the topic of this list but I simply don't know where to ask. I'm trying to use my linux-machine as a YP and NFS server. With SuSE 6.2 it was no problem to make my users mount the /home share on their workstations and to use YP. Now I tried to install a new server (got a new, stronger machine :-))))) using SuSE 6.3. YP works fine but when I mount the /home share I get all of the users directories, but they are empty. I simply don`t know what to do as it worked the same way on SuSE 6.2. Has anything changed in SuSE 6.3 or is it a bug? A desperate admin searching for help P.S.: At the moment I only got one entry in my exports file it is /home (works with 6.2)
