Getting Started with Azure Active Directory: A Step-by-Step Configuration Guide

As organisations increasingly shift to cloud-based services, managing user identities and access rights effectively has become paramount. Azure Active Directory (Azure AD) offers a robust solution to manage user identities and enable secure access to applications. This article provides a comprehensive step-by-step guide to help you get started with Azure Active Directory.

What is Azure Active Directory?

Azure Active Directory is a cloud-based identity and access management service from Microsoft. It allows your employees to sign in and access resources, enabling seamless collaboration across various applications and platforms. Azure AD is integral to Microsoft 365 services and can be extended to third-party applications, making it a versatile choice for enterprises of all sizes.

Prerequisites

Before you dive into configuring Azure AD, ensure you have:

1. An Azure Subscription: If you don’t already have one, you can sign up for a free trial or choose a suitable payment plan.
2. Admin Access: You will need global administrator or privileged role administrator access to perform most configuration tasks.

Step 1: Access the Azure Portal

1. Open your web browser and navigate to the Azure Portal.
2. Sign in using your Azure account credentials.

Step 2: Create an Azure Active Directory Instance

1. In the Azure Portal, search for “Azure Active Directory” in the search bar at the top.
2. Click on “Azure Active Directory” from the search results.
3. In the Azure AD blade, click on “Create a directory” if you do not have an existing directory.
4. Fill in the required information:
   • Organisation name
   • Initial domain name
   • Country or region
5. Click “Create” to establish your Azure AD instance.

Step 3: Configure Domain Names

1. Once your directory is created, navigate to “Custom domain names” in the Azure AD blade.
2. Click on “Add custom domain”.
3. Enter your custom domain name (e.g., yourcompany.com) and click “Add domain”.
4. Follow the verification steps provided by Azure to prove ownership of the domain. This usually involves adding a TXT record to your domain’s DNS settings.

Step 4: Add Users

1. In the Azure AD blade, select “Users”.
2. Click on “New user”.
3. Fill in the user details:
   • User name (this will be their email address)
   • First and last name
   • Roles (you can assign a specific role or leave it as “User”)
4. If necessary, set a temporary password, which the user will be required to change upon first login.
5. Finally, click “Create”.

Step 5: Assign Roles

1. To assign roles, navigate back to the “Users” section in Azure AD.
2. Select the user you wish to assign a role to.
3. Click on “Assigned roles” and then “Add assignments”.
4. Choose the role you wish to assign (e.g., User Administrator, Global Administrator) and click “Add”.

Step 6: Configure Enterprise Applications

1. In the Azure AD blade, click on “Enterprise applications”.
2. Here, you can add applications that your users will access. Click on “New application”.
3. Choose from a gallery of popular applications or add a custom application.
4. Follow the prompts to configure single sign-on (SSO) and user assignment settings.

Step 7: Set Up Conditional Access

1. Navigate to “Security” in the Azure AD blade.
2. Click on “Conditional Access”.
3. Click on “New policy” to create a conditional access rule.
4. Set conditions based on user group, application, location, and risk level, then define the access controls (e.g., require multi-factor authentication).

Step 8: Monitor and Review Settings

1. Regularly review your Azure AD configurations and user access:
   • Use the “Sign-ins” and “Audit logs” features to monitor access events.
   • Review group memberships and role assignments periodically.

Conclusion

Once these configurations are in place, your organisation will be better placed to manage identities securely and efficiently. Azure Active Directory not only simplifies access management but also enhances security through features such as multi-factor authentication and conditional access policies. As you delve deeper into Azure AD, explore functionalities like self-service password reset and identity protection to optimise your user management strategy.

By following this step-by-step guide, you’re well on your way to harnessing the full potential of Azure Active Directory for your organisation.
