A user reported an issue in which the validation step for the Domain Account failed. After reviewing the logs, the root cause of the failure was discovered:
An error (1332) occurred while enumerating the group membership. The member's SID could not be resolved.
This issue is due to ghost users still existing in the User Groups in the machine, most likely the Administrators group. In order to resolve the issue, remove the ghost users from the group and try the validation again.
