When manually adding an Active Directory (AD) user to VMware Identity Manager (vIDM), the domain name field may remain blank even if directory synchronization for groups is functioning correctly. This behavior prevents the user from being correctly identified within the identity provider scope.
You may notice below symptoms:
Users are added manually via Identity & Access Management > Sync Settings > Users using their Distinguished Name (DN).
The sync completes successfully, but the Domain column in the Users & Groups tab is empty for the new user.
Log files (connector-dir-sync.log) may show successful sync but missing attributes for the specific user object.
