[rhelv6-list] NFSv4 not translation UID, GID between freebsd server and rhel63 client

[Jason Keltz]

Hi Antonio,

Thanks for your response.
I need the uid/gid mapping to work for all accounts, not just one.  
Setting the anon account would "fix" the problem for this one account, 
but not for the other 1000 that I intend to map.

Jason.
