I'm using the excellent openfiler 2.6 for a NAS box - with a single share on it for mixed usage.

I would like to keep the share permissions (set through Openfiler for Read only for students and RW for Staff) but then add some subfolders which have more specific permissions (i.e RW for students on some)

Is that possible? I can't seem to find a definitive answer - other than creating another share and setting the permissions that way.
