Thanks for the suggestions. When I'll can go to work I'll start to test the
Ad solution. All my clients are Windows and the only things I need is the
client authentication and permit to some user to access to some shared
folders from the server.
Have you some tutorials/books to help me to configure everything?
Thanks again
