- The Key Distribution Services (KDS) Root Key must be available in the KDS service on the Domain controller.
- The computers and groups that have servers with Active Roles Service installed on them, must be added to the gMSA account.
- The gMSA account must be available in the Local Administrators group where the Active Roles service is installed and in the built-in Administrators group of the domain.
- The gMSA account must have an SQL login with db_Owner permission for Active Roles database.
- The gMSA account name must be unique across domains.
NOTE: Exchange operations cannot be performed on the on-premises Exchange Server environment using the gMSA account. For example, Remote mailbox, User mailbox, or Contact.

Configuring the Active Roles Service account to use a gMSA account
After completion of Active Roles Setup, the Configuration Center enables you to create an instance of the Administration Service to get the Administration Service ready for use.
To configure the Administration Service account to use a gMSA account as the service account during initial configuration
- Start Configuration Center on the computer running the Administration Service.
You can start Configuration Center by selecting Configuration Center on the Apps page or Start menu, depending upon the version of your Windows operating system. For detailed instructions, see Running Configuration Center.
- In the Configuration Center main window, under Administration Service, click Configure
- On the Administration Service page, in the Service Account area, click Browse.
- In the Select User or Service Account dialog box, click Object Types.
- In the Object Types dialog box, select the Service Accounts object type along with the Users object type and click OK.
- In the Service User or Service Account dialog box, click Check Names to select the required gMSA account, and click OK.
The Configure Administration Service dialog box displays the new login name for the gMSA account. The Password field is disabled.
-
Click Next to complete the service account configuration.
If the system running the Active Roles Service is not linked to the gMSA account, then an error is displayed prompting you to check if the system is permitted to use the provided gMSA.
If the gMSA account is not part of the Local Administrators group, then an error is displayed prompting you to check if the gMSA account is a member of the Local Administrator’s group on the system.
-
If all the pre-requisites are met, you can proceed to the next step. Provide the name of the group or user account that will have full access to all Active Roles features and functions through this Administration Service instance (Active Roles Admin). Click Next.
-
Provide the details for the database in which this Administration Service instance will store the configuration data and management history data.
You have the option to create a new database or use an existing database of the current Active Roles version. It is possible to have multiple Administration Service instances use the same database.
|
NOTE: When you create a new database, you can add the DB_owner permission to gMSA account for the new database only after the Administration Service is configured. |
Based on the authentication mode that the Administration Service instance uses when connecting to the database, the Administrative Service uses the relevant credentials:
- With the Windows authentication option, the Administration Service will use the credentials of the service account.
- With the SQL Server authentication option, the Administration Service will use the SQL login name and password you supply in the wizard.
-
After all steps are complete, review the settings on the Ready to Configure summary page and click Configure to complete the configuration.
The Active Roles Admin setting is specific to the instance of the Administration Service. If you have multiple Administration Service instances deployed in your environment, then you need to apply the changes on each computer running the Administration Service.
