The import of UMS administrators from an Active Directory fails, the result list of imported accounts is either empty or some accounts are missing on the list.


Active Directory user accounts may have an empty User Principal Name (UPN). This occurs when updating an older Active Directory (e.g. on Windows NT 4.0) to a new one migrating the AD user accounts to the new AD.


  1. Set the UPN of each AD account to be imported.
  2. Retry the import of AD users in IGEL UMS.
