NFS shouldn't be denied for root as far as I know...  At least I hope 
not, because when a user SSH'es in for example, the automounter (root 
process) has got to be able to mount an NFSv4 home directory for that 
user.  Or maybe the automounter mounts it AS that user after a kerberos 
ticket has been issued....  Not sure.

I can SSH in and SSH talks to PAM ( specifically) and I get 
a ticket when SSH logs me in, so that looks cool.

As Kevin suggested, I tried checking KVNO version numbers on the nfs 
principal and the keytab and the version numbers differ, maybe that is 
the problem...  I feel like I'm close by just one step away...  :)
