I've joined my Terastation Pro II (Firmware 1.23) to our Windows 2000 domain, and use active directory authentication. This part works fine. When I go to share a folder, and select names/groups from active directory list, there are many duplicates of names and groups. Some names work, some don't, and give the user a not authorized error. Where is it getting all of the duplicate names from? There are of course no duplicate names on the server because it doesn't let you do that.
