Hi, I want to use my Linux box as a file server but the thing i want to do is not create users under Linux but to authenticate them from NT PDC. What i want is a group level access if user belongs to a particular group (under NT) he can access that particular group folder. Can i perform this sort of mapping? just create one Master User for each group and when a user for particular group try to log in after authenticate from NT that group's Master UID assigned to him. Or there is any other good way to do this? Thanks.
