[Samba] Shared Folder Stop users altering subfolder structure

[Kevin Hall]

I am working in a school where each class has a class logon eg class1, class2 
etc. and in smb.conf each class is directed to their own folder on the server 
eg /shared/class1, /shared/class2 etc. 

When a pupil navigates to their class folder on the server, they see 
subfolders for each pupil in the class eg sid_smith, joe_bloggs etc. They 
then navigate to their named folder to load/save their work.

My problem is I seem unable to stop pupils changing the folder structure, ie 
deleting, moving or copying a folder. eg sid_smith becomes a subfolder in 
joe_bloggs.

Is it possible or are individual logons the only solution?
