Administrator Privileges Required for VADP Restore?

Experts,

We have changed NetWorker Authentication to Active Directory. Trying to restore a VM leads to the following error Message: Permission denied ... does not have 'Recover Local Data' Privilege .

Adding to a Group with  'Recover Local Data' Privilege doesn't show the expected success. Only adding to Group 'Administrators' enables the restore of the VM.

is currently in a group with the following privileges:

• Remote Access All Clients
• Operate NetWorker
• Monitor NetWorker
• Operate Devices and Jukeboxes
• Recover Local Data
• Recover Remote Data
• Backup Local Data
• Backup Remote Data

Do I have to grant any Administrator privileges do enable VADP restores?

Many thanks

Chris
