I hope this is an easy task to implement basically I 'need' to point the currently logged in user's documents,etc to a folder on the server. I know this an easy task on a windows server and client through group policy.
Just mount the network share on the Documents folder
Move any existing docs out of the local user Documents folder first.
Then add this to fstab
server.local:/srv/user/Documents /home/user/Documents nfs _netdev,auto 0 0
Change server.local to a valid dns name of your server.
Tell it to do the mounts now
Now your local Documents folder points to your server location.
You would need your nfs server in place first, and nfs-tools installed locally.
This is a manual way to do it for one user on one workstation. For multiple users or a generic version you'll need something smarter using LDAP or NSS.
