Active Directory user shows up at cn=username,cn=users,dc=domain

I have Active Directory integration working and have started rolling out the client to specific users for testing as a pilot. Three accoutns were added and setup just fine, however I added a fourth called shipping and it shows up as cn=shipping,cn=users,dc=domain,dc=com@exchange2007server

I Googled and did not come up with much, its display name is different that its name and I don’t see a computer with that same name either, so I don’t really know what the problem is but I would like to get it resolved, anyone know? Using version OpenFire 3.6.2, Windows Server 2003 AD, Exchange 2007.
