I followed the guide and it works well …
I made the modification to the permissions as described here:
https://wiki.samba.org/index.php?title=Roaming_Windows_User_Profiles&_Windows_Profiles=
chgrp -R “Domain Users” /var/lib/nethserver/profiles/
chmod 1757 /var/lib/nethserver/profiles/
It is to be inserted absolutely in the next versions !!!
I have edit DOMAIN with Remote Server Administration Tools (RSAT)
