I have a technician who is not visible in "Technicians", nor in "Requesters". He is visible as a Technician in the drop down list for some call types - however in the database there are three entries for him - 2 with a zero technician ID and one with a valid technician ID.

I'd like to clear the issue completely and add him as a technician - ideally via an Active Directory import as a requestor, then updating him to be a technician....
