We attempted to create a user in CRM 4.0 and it failed.  Unfortunately, we don't have the original error message.
We can not find a user with that domain name via advanced find searching both active and inactive records.
I have also searched the domainname field in the systemuserbase table for the specific login name without success.
But whenever we attempt to create this user in CRM we receive the following error:
"You are attempting to create a user with a domain name logon that is already used by another user.  Select another domain logon and try again."
Any thoughts on why CRM thinks this user already exists?
