SQL Active Directory User ID SID Mismapings

Sometimes login mapping issues exist where you least expect them
This is not the traditional SQL login SID mismap issue that is frequently encountered and discussed here. This mismap was a new one on me so I thought id document it.
When trying to add a new Windows login for SQL Server 2005 or 2008 (probably earlier versions but not tested) you may wind up with this error message
Msg 15025, Level 16, State 2, Line 1
