If i read it correctly what Luc showed. 

Let say i have as homedir : /usagers1/username
/usagers1/username  Mounts on fs1.example.com:/&

If i change it to /usagers2/username i move to server2 
/usagers2/username   Mounts on fs2.example.com:/&

I never used automount like that, but if it works, i'll document it.
So i wait for Luc his success message :-)) 

Where if often goes wrong is the missing SPNs, then a user can mount his homedir
The quick/dirty fix is root/SPN, but better is nfs/FQ.DN.TLD (@Realm)

Always ears and open for new ideas :-) 
How would you do this?
