Symptoms

NetWorker Module for Microsoft (NMM) Active Directory Granular backup fails.

Cause

The root cause of this issue is related to user permissions of the user running the backup.
The issue is that the user is missing read permissions for the Active Directory abstract schema.




 

Resolution

To resolve this issue, perform the following steps:

  • Create a Domain User account with 'Backup Operators' permissions to correctly read the Active Directory abstract schema.
  • Run the NMM Active Directory granular restore with that privileged user.
