Unlock the Power of Identity Management with Microsoft Azure Active Directory and Microsoft Graph API

Identity management is a critical component of modern IT infrastructure, enabling organizations to manage the identities and access of internal users such as employees, contractors, partners, and consumers as well. This article explores the concept of identity management, its benefits for business owners, and how to integrate Microsoft Azure Active Directory (AAD) and Microsoft Graph API to get access to custom business applications or standard corporate apps like Microsoft Office 365, SharePoint, OneDrive, Outlook Mail, Calendar, etc.

What is Identity Management?

Identity management involves handling the identities of users. This includes managing access to corporate resources, applications, and services. Effective identity management ensures that only authorized users have access to the right resources at the right times for the right reasons.

Key Features of Identity Management

1. Directory Services: Maintains a directory of all users, including their roles, permissions, and attributes.
2. Single Sign-On (SSO): Enables users to log in once and gain access to multiple applications without needing to log in separately to each one.
3. Role-Based Access Control (RBAC): Controls access to resources based on users’ roles within the organization.
4. Provisioning and De-provisioning: Automatically manages the lifecycle of user accounts, including creating, updating, and disabling accounts as users join, move within, or leave the organization.
5. Security and Compliance: Ensures that access policies comply with internal and external security standards and regulations.

Example

A large enterprise might use Microsoft Azure Active Directory to manage employee access to various corporate applications like Office 365, SharePoint, OneDrive, Outlook Mail, Calendar, and internal HR systems. Employees use their organizational credentials to log in to all required applications via SSO.

Benefits of Integrating with Microsoft Azure Active Directory

Integrating identity management with Microsoft Azure Active Directory (AAD) offers several benefits for business owners:

1. Enhanced Security: Azure AD provides robust security features such as Multi-Factor Authentication (MFA), conditional access policies, and identity protection, reducing the risk of unauthorized access and data breaches.
2. Simplified User Management: Centralized management of user identities and access rights simplifies administrative tasks and improves efficiency.
3. Improved User Experience: SSO capabilities allow users to access multiple applications with a single login, enhancing productivity and reducing password fatigue.
4. Scalability: Azure AD scales to meet the needs of organizations of all sizes, from small businesses to large enterprises.
5. Compliance: Azure AD helps organizations comply with regulatory requirements by providing tools for identity governance, access reviews, and audit logs.

Building a Spring Boot Web MVC Application with Azure AD Integration

This section demonstrates how to build a Spring Boot Web MVC application that provides API endpoints integrated with Microsoft Azure Active Directory for managing organizational identities. The application implements the "Resource Owner Password Credentials (ROPC) Authentication" scheme in Active Directory, leveraging Microsoft Graph APIs. This scheme is suitable for scenarios where a custom registration and authentication process with a tailored UI/UX is a business requirement for your organization.

Checkout my Github repository to see the source code of the Spring Boot Web MVC app with AAD Integration and Microsoft Graph API usage.

Azure AD Authentication scheme

Azure AD Configuration Guide

Step 1: Sign in to Azure

Sign in to Azure and connect to the Azure AD tenant where you would like to manage users.

Step 2: Register a New Application

1. On the left menu, select App registrations.

2. Click + New Registration.

   

3. Under Name, enter a unique application name.

4. Under Supported account types, select Accounts in this organizational directory only.

5. Click Register.

   

Step 3: Create a Client Secret

1. Select the new registered app from the list of App Registrations.

2. Select Certificates & secrets from the left menu.

3. Click + New Client Secret.

4. Provide a Description and appropriate Expiry. If you select 1 or 2 years, the service principal must be refreshed with a new client secret on the anniversary of its creation.

5. Click Add.

6. Create a copy of the client secret and store it in a safe place. This is the only time it is displayed. This is needed to add the account to the Vault.

   

Step 4: Assign API Permissions

1. Assign API Permissions to the Registered Core Service (platform) App.

2. Search Azure for Azure AD roles and administrators.

   

3. Search for the role User Administrator. The User Administrator role gives the application sufficient permissions to change most passwords, with the exception of Authentication Admin, Global Admin, Privileged Authentication Admin, and Privileged Role Admin.

4. Click the Role or the ellipsis button for the role and then click Description.

5. On the left menu, click Assignments (if not already selected).

6. Click + Add assignments.

7. In the Search box, type the name of the registered app that was created earlier. Registered apps are not listed with users and can only be found this way.

   

8. The previously created registered app is visible in the search results. Select it and click Add. Service Principal assignment is done, thus the application will have enough rights to use Graph API to create users and change user passwords in Active Directory.

Example of Organizational Identity Management through Microsoft Graph API

A company with 500 employees needs to manage access to internal applications and services. It uses Azure AD and Microsoft Graph API to:

• Provision new employee accounts and assign them to appropriate groups based on their department.
• Implement SSO so employees can access email, collaboration tools, and intranet with one set of credentials.
• Conduct regular access reviews to ensure that only current employees have access to sensitive data.

Conclusion

Integrating Microsoft Azure Active Directory for identity management provides significant benefits for business owners, including enhanced security, simplified user management, and improved user experience. By following the steps outlined in this article, you can configure Azure AD and leverage its capabilities to manage user identities effectively.
