[Samba] server linux

[fondomi]

Hello

I am the administrator of a server linux with 25 clients.
Lasdt year : no problem.
Each children saves files in the same directory on the server.
But now, the teachers want that the children have different directories.
Then 600 children  have a directory on the server and each directory is secured by a password.
When they want to save a file on the server, a lot of them may not open their directory.
How can I solve this problem.

Thank you very much for an answer
