[K12OSN] smbldap - root cannot access all folders on nfs mounted /home

[john]

Hi Krsnendu,

I believe the line:

 /home                    192.168.0.0/255.255.255.0(rw,root_squash,sync)

Tells the machine with the exported share to NOT allow root users on other
machines to have rootly powers on the share. Otherwise anyone who has root
on their own machine can mount any nfs share and automagically have root on
it as well.  You'll probably need to export this directory with the
*no_root_squash
*option. Here's a little blurb on NFS that might help.
