That is expected, else something bad would exists in the configuration
of the NAS.

Maproot is the easiest as it gives complete access to the NFS exported
Now you may consider that for security reason, users of client-machine
1 should only be allowed to NFS mount their own home directory.
In that case, you may need the users of client-machine 1 to exist on
client-machine 1 and on the server, etc for machine 2... Actually I
never had this case when a user account only exists on an NFS client
but not on the NFS server, so I am not too sure. I guess that user ID
of the users should be different on every client system.
You may consider an LDAP directory for your users, where the server
would see all the users, but each client-machine would see only the
users belonging to it (I thing that there is an "host" attributes, so
client-1 only sees the users with host=client-1).
