Is it possible to have 2 different exports for the same directory i.e. "/ifs/data", and have 2 different sets of permissions associated with them and not cause any conflicts with access to that directory for ALL users? Let me know.
Are you controlling user access from AD level? NFS exports typically deals with client IP ( not at user level)
User access via NFS is controlled via UNIX-style permissions, read, write and modify. You cannot create an NFS export that controls those permissions - they are only at the filesystem/directory/file level.
You can, however, create multiple NFS exports where one export is read-only and one export is read-write. For example, you can export /ifs/data1 as NFS read-write to a series of clients, then export /ifs/data1 as NFS read-only to a different series of clients. But, again, that does not control user access.
Let me know if that helps!
