Trying to wrap my brain around user authentication for NFSv4

Show all headers | View raw

I've an extremely heterogeneous environment, with many [virtual] hosts 
that have completely independent sets of users.  That is, john@hostA and 
john@hostB are unrelated.

With NFSv3, this is a non-issue.  The NFS servers export different 
volumes to hostA and hostB, and the NFS clients use their UIDs as they 
would on local storage.  Because there is no overlap between the volumes 
exported to the different NFS clients, this is not a problem.

I'm not clear how to get this effect on NFSv4.  It seems to presume a 
shared set of users over all NFS clients (even if the names and UIDs of a 
given user might differ from client to client).  So where john@hostA 
might be the same user as johnsmith@hostB, NFSv4 maps these together well.

Yet I cannot see how to get the effect I need, where the sets of users 
are independent.

Am I missing something?

Thanks...

	Andrew
