Per User Authentication for Per User Authorization

[Jan Sanders]

Hello,

I would like to authenticate users of my NFSv4 server users using 
Kerberos. The  rpc.gssd -n  option makes it possible to use Kerberos 
credentials other than machine (or host) credentials.

Is there a way to tell NFSv4: Kerberos principal X may mount the 
directory Y using NFSv4. But Kerberos principal Z may not.

TIA
