Step 4. Select Active Directory Group
[This step applies only if you have selected the Creating service account automatically option at the Select Service Account Type step of the wizard]
At the Active Directory step of the wizard, add your Azure AD application to an Azure Active Directory group to be able to back up Azure resources as a group:
- Select the Add specified application to this AD group check box.
- From the list of available groups, select the necessary group.
For a group to be displayed in the list, it must be created in the Microsoft Azure portal as described in Microsoft Docs.
Adding service accounts to AD groups allows users to limit access of the service accounts only to specific Azure subscriptions.
