nfs RPC: AUTH_GSS upcall timed out and running nfs v4 without full kerberos : how?

[hanasaki]

1. Below appears to require krb for auth.  Is this correct?  How can nfs 
v4 be setup and used over tcp? udp? and not require a full kerberos 
server setup?

2. The stat issue is ok.  It takes a long time to timeout which is 
causing problems.  Using the full directory path locally on the nfs 
server works ok without stat issue or long timeouts.

3. the user daemon does appear to be running fine.

Simply ensure that rpc.gssd is running on your NFS clients.  The exact procedure varies among Linux distributions.  There is no need to perform any other configuration.
