You don't want to import users - just allow plain vanilla authentication of the web server and trust the usernames that then get presented to the system. Most amateur systems start off with the design of a hardcoded list of local users, but this would never scale. Most systems of that type then get trapped in a loop of importing the list of users every night from some other source (e.g. an AD) but that's broken as well, especially for a help desk.
