Using Debian 4.0. I want to create one Share (eg. Files) and have subdirectories for each department. This is so that users only have to mount one share. So it looks something like this: Files - Accounting - Human Resources - Enginnering - etc Using Samba how can I give subdirectories different permissions using Active Directory. Would this be done by creating corresponding linux groups and assign them to the directories at the linux level? If so how do I map Active Directory users/groups to their respective Linux users/groups. I'm trying to replace a Windows machine that is currently acting as a file server.
