You may have missed this little gem. Set the stickybit for ALL of your
share points: ex: "chmod +t /home". This will cause the root accounts
on remote systems to be treated as a non-root account like nobody
(60001), noaccess (60002), or access denied (-1) depending the options
specified in your share statement. Linux is supposed to 'root squash'
(change client root uid's to 65534) by default. remove "no_root_squash"
from your export file.
Solaris 2.6/NIS+ environment set anon=-1 in /etc/dfs/dfstab:
share -F nfs -o anon=-1 -o rw /share.
Linux/NIS env set anonuid=-1 in /etc/exports: /home
