Tutorial: Enable Azure Active Directory only authentication with Azure SQL

APPLIES TO: Azure SQL Database Azure SQL Managed Instance

This article guides you through enabling the Azure AD-only authentication feature within Azure SQL Database and Azure SQL Managed Instance. If you are looking to provision a SQL Database or SQL Managed Instance with Azure AD-only authentication enabled, see Create server with Azure AD-only authentication enabled in Azure SQL.

In this tutorial, you learn how to:

• Assign role to enable Azure AD-only authentication
• Enable Azure AD-only authentication using the Azure portal, Azure CLI, or PowerShell
• Check whether Azure AD-only authentication is enabled
• Test connecting to Azure SQL
• Disable Azure AD-only authentication using the Azure portal, Azure CLI, or PowerShell

Prerequisites

• An Azure AD instance. For more information, see Configure and manage Azure AD authentication with Azure SQL.
• A SQL Database or SQL Managed Instance with a database, and logins or users. See Quickstart: Create an Azure SQL Database single database if you haven't already created an Azure SQL Database, or Quickstart: Create an Azure SQL Managed Instance.

Assign role to enable Azure AD-only authentication

In order to enable or disable Azure AD-only authentication, selected built-in roles are required for the Azure AD users executing these operations in this tutorial. We're going to assign the SQL Security Manager role to the user in this tutorial.

For more information on how to assign a role to an Azure AD account, see Assign administrator and non-administrator roles to users with Azure Active Directory

For more information on the required permission to enable or disable Azure AD-only authentication, see the Permissions section of Azure AD-only authentication article.

1. In our example, we'll assign the SQL Security Manager role to the user UserSqlSecurityManager@contoso.onmicrosoft.com. Using privileged user that can assign Azure AD roles, sign into the Azure portal.

2. Go to your SQL server resource, and select Access control (IAM) in the menu. Select the Add button and then Add role assignment in the drop-down menu.

   

3. In the Add role assignment pane, select the Role SQL Security Manager, and select the user that you want to have the ability to enable or disable Azure AD-only authentication.

   

4. Click Save.
