Azure Service Principal

Azure Service Principal is role-based application-based authentication. This means that authentication is done per application, rather than per user. All tasks taken by the app are done without a default user context, but based on the assigned roles. The application access to the resources is controlled through the assigned roles' permissions.

To use Azure Service Principal authentication, you must:

• Set up the ability to assign a role to the authentication application. To do this, create a custom OAuth AD application, as described in Creating a Custom OAuth Application.
• Register an application with an Azure AD tenant, to create a new service principal that can be used with the role-based access control, to access resources in your subscription.

Do the following:

1. Create a custom Azure AD application, as described in Creating a Custom OAuth Application.
2. Assign a role to the application:
   1. Use the search bar to search for the Subscriptions service.
   2. Open the Subscriptions page.
   3. Select the subscription to which to assign the application.
   4. Open the Access control (IAM).
   5. Select Add > Add role assignment. Azure Analysis Services opens the Add role assignment page.
   6. Assign your custom Azure AD application the role of Owner.
