Thanks for all the suggestions!  As this is for a simple home rollout  ldap
and NIS are a little over the top.  If it were a big picture item I would
definitely choose ldap.

I found in order for this to work I had to cp the /etc/passwd and /etc/group
to the local machine that is connecting to the NFS server share.

Again thanks for all the info!
