How can I prohibit network users from accessing other user's home folders using Server permissions? I have a 10.8 server, network users on a shared drive 'User Data' - used as a AFP for home folders, OD is on. All users are part of a group 'students 2013/14'.

My network user can login via OD over a network, however the permissions are not set correctly, since network user accounts can access all other users folder read/write on the sharepoint.

Question:
How can I set the permissions in Server.app correctly so that network users can login, use their server based home folder w/r but not access other network user home folders using the student 2013/14 group?
Launch Server.app
Click "File Sharing."
Click "Users."
Use Minus Sign to Remove Certain Users from Certain Folders.
