Event ID 28
APP AT - Customer ID: 3 - An error occured in EmployeeSynchroniser::SynchroniseGroupMembers. System.DirectoryServices.DirectoryServicesCOMException (0x80072029): Inappropriate authentication.
This condition and error will occur when the Anonymous Access to Domino Directory has been disabled. By design, Anonymous Access is required to allow the synchronization account, which is typically the Vault Service Account, to read the user properties needed for synchronization from the Domino Directory to the DA CM instance.
Ensure that Anonymous Access to Domino Directory is enabled.
Applies to all supported versions of DA.
