by default NFS exports have the the `root_squash' option set, this 
means that root on the client is treated as the nobody user, which 
essentially means that root can only access world readable files.

if all the clients who can mount the share are secure and trusted, 
add no_root_squash to the export options of /etc/exports on the 
server.  like so:

/home	pluto(no_root_squash)

you can add any other options there too, comma separated.
