Applies to: Azure SQL Database Azure SQL Managed Instance

This article guides you through enabling the Microsoft Entra-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 Microsoft Entra-only authentication enabled, see Create server with Microsoft Entra-only authentication enabled in Azure SQL.

Note

Microsoft Entra ID was previously known as Azure Active Directory (Azure AD).

In this tutorial, you learn how to:

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

Prerequisites

A Microsoft Entra tenant. For more information, see Configure and manage Microsoft Entra 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 Microsoft Entra-only authentication

In order to enable or disable Microsoft Entra-only authentication, selected built-in roles are required for the Microsoft Entra 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 a Microsoft Entra account, see Assign administrator and non-administrator roles to users with Microsoft Entra ID

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

In our example, we'll assign the SQL Security Manager role to the user [email protected]. Using privileged user that can assign Microsoft Entra roles, sign into the Azure portal.
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.
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 Microsoft Entra-only authentication.
Click Save.

Enable Microsoft Entra-only authentication

Enable in SQL Database using Azure portal

To enable Microsoft Entra-only authentication in the Azure portal, follow these steps:

Using the user with the SQL Security Manager role, go to the Azure portal.
Go to your SQL server resource, and select Microsoft Entra ID under the Settings menu.
If you haven't added an Microsoft Entra admin, you'll need to set this before you can enable Microsoft Entra-only authentication.
Check the box for Support only Microsoft Entra authentication for this server.
The Enable Microsoft Entra-only authentication popup will show. Select Yes to enable the feature and Save the setting.

Enable in SQL Managed Instance using Azure portal

To enable Microsoft Entra-only authentication in the Azure portal, see the steps below.

Using the user with the SQL Security Manager role, go to the Azure portal.
Go to your SQL managed instance resource, and select Microsoft Entra admin under the Settings menu.
If you haven't added an Microsoft Entra admin, you'll need to set this before you can enable Microsoft Entra-only authentication.
Select the Support only Microsoft Entra authentication for this managed instance checkbox.
The Enable Microsoft Entra-only authentication popup will show. Select Yes to enable the feature and Save the setting.

Enable in SQL Database using Azure CLI

To enable Microsoft Entra-only authentication in Azure SQL Database using Azure CLI, see the commands below. Install the latest version of Azure CLI. You must have Azure CLI version 2.14.2 or higher. For more information on these commands, see az sql server ad-only-auth.

For more information on managing Microsoft Entra-only authentication using APIs, see Managing Microsoft Entra-only authentication using APIs.

Note

The Microsoft Entra admin must be set for the server before enabling Microsoft Entra-only authentication. Otherwise, the Azure CLI command will fail.

For permissions and actions required of the user performing these commands to enable Microsoft Entra-only authentication, see the Microsoft Entra-only authentication article.

Sign into Azure using the account with the SQL Security Manager role.
```
az login
```
Run the following command, replacing <myserver> with your SQL server name, and <myresource> with your Azure Resource that holds the SQL server.
```
az sql server ad-only-auth enable --resource-group <myresource> --name <myserver>
```

Enable in SQL Managed Instance using Azure CLI

To enable Microsoft Entra-only authentication in Azure SQL Managed Instance using Azure CLI, see the commands below. Install the latest version of Azure CLI.

Sign into Azure using the account with the SQL Security Manager role.
```
az login
```
Run the following command, replacing <myserver> with your SQL server name, and <myresource> with your Azure Resource that holds the SQL server.
```
az sql mi ad-only-auth enable --resource-group <myresource> --name <myserver>
```

Enable in SQL Database using PowerShell

To enable Microsoft Entra-only authentication in Azure SQL Database using PowerShell, see the commands below. Az.Sql 2.10.0 module or higher is required to execute these commands. For more information on these commands, see Enable-AzSqlInstanceActiveDirectoryOnlyAuthentication.

Note

The Microsoft Entra admin must be set for the server before enabling Microsoft Entra-only authentication. Otherwise, the PowerShell command will fail.

For permissions and actions required of the user performing these commands to enable Microsoft Entra-only authentication, see the Microsoft Entra-only authentication article. If the user has insufficient permissions, you will get the following error:

Enable-AzSqlServerActiveDirectoryOnlyAuthentication : The client
'[email protected]' with object id
'<guid>' does not have authorization to perform
action 'Microsoft.Sql/servers/azureADOnlyAuthentications/write' over scope
'/subscriptions/<guid>...'

Sign into Azure using the account with the SQL Security Manager role.
```
Connect-AzAccount
```
Run the following command, replacing <myserver> with your SQL server name, and <myresource> with your Azure Resource that holds the SQL server.
```
Enable-AzSqlServerActiveDirectoryOnlyAuthentication -ServerName <myserver>  -ResourceGroupName <myresource>
```

Enable in SQL Managed Instance using PowerShell

To enable Microsoft Entra-only authentication in Azure SQL Managed Instance using PowerShell, see the commands below. Az.Sql 2.10.0 module or higher is required to execute these commands.

For more information on managing Microsoft Entra-only authentication using APIs, see Managing Microsoft Entra-only authentication using APIs.
