Extracted from the original post

“If you receive this message it’s usually because a user in your organization is deleted, and re-created using the same domain and same account name. This may have been because of a user was deleted by accident, or a previous employee who left your organization and was then rehired.

For example, my account in the ”NA” domain with the same account name of john.smith (NA\john.smith). The account was deleted and re-created with the same account name (NA\john.smith).

1) Remove the user completely and re-add, or

2) Use the STSADM -o migrateuser command
