Enabling Group Writeback for Azure AD Security Groups

Introduction to Azure AD Group Writeback

Azure Active Directory (Azure AD) provides a rich set of features for identity and access management, including the ability to manage groups. One of the powerful functionalities is Group Writeback, which allows you to synchronize security groups from Azure AD back to your on-premises Active Directory. This is particularly useful for organizations that have a hybrid environment, enabling seamless access management across both cloud and on-premises resources.

Prerequisites for Group Writeback

Before you can enable Group Writeback, there are several prerequisites that you must meet. First, you need to have an Azure AD Premium license. Additionally, you should have the Azure AD Connect tool installed and configured to sync your Azure AD with your on-premises Active Directory. Make sure that the appropriate permissions are set up to allow you to make changes to the Azure AD Connect configuration.

PowerShell Command for Enabling Group Writeback

To enable Group Writeback for Azure AD security groups, you can use the Azure AD PowerShell module. This module provides a command-line interface to manage Azure AD resources effectively. Below is a PowerShell command that you can use to enable the Group Writeback feature:

Install-Module AzureAD
Connect-AzureAD
Set-AzureADDirectorySetting -Id (Get-AzureADDirectorySetting | Where-Object {$_.DisplayName -eq "Company branding"}).Id -DirectoryWritebackEnabled $true

Let’s break down the command:

• Install-Module AzureAD: This command installs the Azure Active Directory module if it's not already installed.
• Connect-AzureAD: This command connects your PowerShell session to your Azure AD tenant. You will be prompted to enter your credentials.
• Set-AzureADDirectorySetting: This command allows you to update the directory settings, specifically enabling directory writeback.
• Get-AzureADDirectorySetting: Here, this command fetches the directory settings and filters them to find the relevant setting for your organization.

Verifying the Group Writeback Configuration

After you have executed the command, it is essential to verify that the Group Writeback feature has been enabled successfully. You can do this by running the following command:

Get-AzureADDirectorySetting | Where-Object {$_.DisplayName -eq "Company branding"}

This command retrieves the current directory settings, and you should see the attribute for DirectoryWritebackEnabled set to true. This confirmation indicates that the Group Writeback feature is now active and functioning as expected.

Conclusion

Enabling Group Writeback for Azure AD security groups is a straightforward process when using PowerShell. By following the steps outlined above, you can ensure that your Azure AD groups are synchronized back to your on-premises Active Directory, providing a seamless experience for users across both environments. Always remember to check your configurations and permissions to prevent any issues during the setup process.
