Adding Dynamic OIDC Parameters in Spring Boot Security with OAuth2

In modern web applications, managing user authentication effectively is crucial for both security and user experience. If you're using Spring Boot with OAuth2 for authentication, you might encounter a situation where you need to add dynamic OpenID Connect (OIDC) parameters to your authorization requests. This is particularly useful when you want to customize the login flow based on certain conditions or data received from the user before they are authenticated.

In this guide, we'll tackle the question: How do I add OIDC token request parameters dynamically in my app code? Specifically, we’ll discuss how to dynamically include the domain_hint parameter based on data received from unauthenticated users via your controller.

Understanding the Basics

Before diving into the solution, let's clarify what the domain_hint parameter is. The domain_hint is used to suggest to the authorization server which domain the user should use to log in. This can enhance the user experience by streamlining the authentication process, particularly in multi-tenant applications.

Now, let's explore how to dynamically add this parameter to your authorization requests using Spring Security with OAuth2 support.

Solution: Implementing a Custom OAuth2AuthorizationRequestResolver

To achieve our goal, we will need to implement a custom OAuth2AuthorizationRequestResolver. This resolver will allow us to inspect incoming requests and modify or add parameters before the authorization request is sent to the authorization server. Here's how to do that step-by-step.

Step 1: Create Your Custom Authorization Request Resolver

You need to create a class that implements the OAuth2AuthorizationRequestResolver interface. Within this class, you can implement the logic to dynamically add the domain_hint parameter based on the user's request data.

Here’s a simplified version of what your class might look like:

Step 2: Integrate Your Custom Resolver with Spring Security

Once you have your custom authorization request resolver in place, the next step is to integrate it into your Spring Security configuration. You can do this by customizing the oauth2Login configuration within your security setup.

Summary

To dynamically add OIDC parameters like domain_hint in your Spring Boot application, implementing a custom OAuth2AuthorizationRequestResolver is an effective approach. By following the steps outlined in this post, you can enhance your application's authentication flow and provide a better experience for your users.

Key Takeaways

Implementing a Custom Resolver: By creating your own OAuth2AuthorizationRequestResolver, you gain control over the parameters sent in the authorization request.

Integrating with Spring Security: Make sure to integrate your custom resolver in the security configuration to ensure it processes requests correctly.

With this knowledge, you're now equipped to better handle dynamic parameters in your Spring Boot OAuth2 authentication flow. Happy coding!
