Use Microsoft Entra ID to authenticate to Azure

  • บทความ

The Microsoft Entra ID service enables a number of administrative tasks, such as user management, domain management, and single sign-on configuration. This article describes how to use Microsoft Entra ID within Azure Automation as the provider for authentication to Azure.

Install Microsoft Entra modules

You can enable Microsoft Entra ID through the following PowerShell modules:

  • Azure Active Directory PowerShell for Graph (AzureRM and Az modules). Azure Automation ships with the AzureRM module and its recent upgrade, the Az module. Functionality includes non-interactive authentication to Azure using Microsoft Entra user (OrgId) credential-based authentication. See Microsoft Entra ID 2.0.2.76.

  • Microsoft Entra ID for Windows PowerShell (MSOnline module). This module enables interactions with Microsoft Online, including Microsoft 365.

Note

PowerShell Core does not support the MSOnline module. To use the module cmdlets, you must run them from Windows PowerShell. You're encouraged to use the newer Azure Active Directory PowerShell for Graph modules instead of the MSOnline module.

Note

Azure AD and MSOnline PowerShell modules are deprecated as of March 30, 2024. To learn more, read the deprecation update. After this date, support for these modules are limited to migration assistance to Microsoft Graph PowerShell SDK and security fixes. The deprecated modules will continue to function through March, 30 2025.

We recommend migrating to Microsoft Graph PowerShell to interact with Microsoft Entra ID (formerly Azure AD). For common migration questions, refer to the Migration FAQ. Note: Versions 1.0.x of MSOnline may experience disruption after June 30, 2024.

Preinstallation

Before installing the Microsoft Entra modules on your computer:

  • Uninstall any previous versions of the AzureRM/Az module and the MSOnline module.

  • Uninstall the Microsoft Online Services Sign-In Assistant to ensure correct operation of the new PowerShell modules.

Install the AzureRM and Az modules

Note

To work with these modules, you must use PowerShell version 5.1 or later with a 64-bit version of Windows.

  1. Install Windows Management Framework (WMF) 5.1. See Install and Configure WMF 5.1.

  2. Install AzureRM and/or Az using instructions in Install Azure PowerShell on Windows with PowerShellGet.

Install the MSOnline module

Note

To install the MSOnline module, you must be a member of an admin role. See About admin roles.

  1. Ensure that the Microsoft .NET Framework 3.5.x feature is enabled on your computer. It's likely that your computer has a newer version installed, but backward compatibility with older versions of the .NET Framework can be enabled or disabled.

  2. Install the 64-bit version of the Microsoft Online Services Sign-in Assistant.

  3. Run Windows PowerShell as an administrator to create an elevated Windows PowerShell command prompt.

  4. Deploy Microsoft Entra ID from MSOnline 1.0.

  5. If you're prompted to install the NuGet provider, type Y and press ENTER.

  6. If you're prompted to install the module from PSGallery, type Y and press ENTER.

Install support for PSCredential

Azure Automation uses the PSCredential class to represent a credential asset. Your scripts retrieve PSCredential objects using the Get-AutomationPSCredential cmdlet. For more information, see Credential assets in Azure Automation.

Assign a subscription administrator

You must assign an administrator for the Azure subscription. This person has the role of Owner for the subscription scope. See Role-based access control in Azure Automation.

Change the Microsoft Entra user's password

To change the Microsoft Entra user's password:

  1. Log out of Azure.

  2. Have the administrator log in to Azure as the Microsoft Entra user just created, using the full user name (including the domain) and a temporary password.

  3. Ask the administrator to change the password when prompted.

Configure Azure Automation to manage the Azure subscription

For Azure Automation to communicate with Microsoft Entra ID, you must retrieve the credentials associated with the Azure connection to Microsoft Entra ID. Examples of these credentials are tenant ID, subscription ID, and the like. For more about the connection between Azure and Microsoft Entra ID, see Connect your organization to Microsoft Entra ID.

Create a credential asset

With the Azure credentials for Microsoft Entra available, it's time to create an Azure Automation credential asset to securely store the Microsoft Entra credentials so that runbooks and Desire State Configuration (DSC) scripts can access them. You can do this using either the Azure portal or PowerShell cmdlets.

Create the credential asset in Azure portal

You can use the Azure portal to create the credential asset. Do this operation from your Automation account using Credentials under Shared Resources. See Credential assets in Azure Automation.

Create the credential asset with Windows PowerShell

To prepare a new credential asset in Windows PowerShell, your script first creates a PSCredential object using the assigned user name and password. The script then uses this object to create the asset through a call to the New-AzureAutomationCredential cmdlet. Alternatively, the script can call the Get-Credential cmdlet to prompt the user to type in a name and password. See Credential assets in Azure Automation.

Manage Azure resources from an Azure Automation runbook

You can manage Azure resources from Azure Automation runbooks using the credential asset. Below is an example PowerShell runbook that collects the credential asset to use for stopping and starting virtual machines in an Azure subscription. This runbook first uses Get-AutomationPSCredential to retrieve the credential to use to authenticate to Azure. It then calls the Connect-AzAccount cmdlet to connect to Azure using the credential.
