Host based authentication

But the server trusts the uid/gid that the client machine presents,  
doesn't it? And that's not the case with kerberos auth. where the  
client machine must be able to supply the user's credentials to get  
the user's privs.

What I was asking about is whether there is a way to get an NFSV4  
server to trust the clients and allow all privs to user's files, but  
only when the client machine can supply machine credentials. So it's  
host-based authentication, but with machine credentials instead of  
just by IP address.
