Are you mapping directly to the users home folder, or are they mapped to a folder that has all the home folders in it.
For example: the top directory is HOME
The users directory is: UserA
Are you mapping to \home? or \HOME\UserA?
In our enviorment, we map directory to the Users Directory. For the HOME folder. for all users is Read & Execute, List Folder Conents, and Read for ALLOW.
Then when the users folder is created, they get full access to their folder.
So in other words, they don't see HOME or their folder, just the contents of their folder. Limit what they see goes along ways.
