This README is an overview of an AttainIT Technologies prototype for demonstrating Spring Boot authentication with Microsoft 365 (formerly known as Office 365). This prototype is discussed in a series of articles on the AttainIT Technologies Blog, with the first article found here.

Overview

This prototype demonstrates integrating Spring Security with Microsoft 365 (Azure AD). It is a simple web appplication (currently one page only) accessed by an authentication against an existing Microsoft 365 subscription/domain. Once logged in, the root page will show several properties about the authenticated user.

This application is designed to be run only from a developers workstation. To run this application securely from behind a DNS address, additional configuration would needed. Specifically, additional redirect URIs must be created within Azure AD.

Developer Workstation Notes

There is one properties file missing from this GitHub repository due to security concerns. It is explicitly referenced in the .gitignore file to prevent it from being pushed to GitHub. It order to run this application, the following file must be created in src/main/resources:

sensitive.properties

azure.activedirectory.tenant-id=your-azure-ad-tenant-id
azure.activedirectory.client-id=your-azure-ad-registered-application-id
azure.activedirectory.client-secret=your-azure-ad-client-secret

Once the application is running, it can be accessed via:

http://localhost:8080

Note that the local application is running over http but the backend authentication to Microsoft 365 is running over https.
