Problem Importing 1 Requester from AD

Problem Importing 1 Requester from AD

I'm trying to import one requester from Active Directory.  When I import him by username, the result window shows:

Total Requesters in Active Directory - 1
Added Records - 0
Overwritten Records - 1
Failed Records - 0

However, when I search for that username in the Requesters list, no results are found.  He's also not listed under Technicians.

He was once a technician, now a regular requester.

I did try to manually create his account, but I receive an error that a person with that username already exists.

It looks like there might be some database corruption.  Any way to remove him from the database directly, then import again?
