--- Comment #4 from Rick Macklem <rmacklem@FreeBSD.org> ---
So may i ask: 
a) nfsuserd + Kerberos5 would achive the correct mapping of the uids/gids.
b) nfsuserd without nis/ldap/kerberos cant do that.

Is this right?

Yes.

If you do not want to have a uniform uid/gid space
(ie. same numbers assigned to the names across all clients
 and server), the only way it can work is for Kerberized
mounts.

For Kerberized mounts, uids/gids never go on the wire.
You still need a uniform user/group name, which is also
consistent with the Kerberos user principal names (for
the user names).
