How to Fix Kafka UI AKHQ Basic User Authentication Issues

If you've been using AKHQ to monitor your Kafka cluster, you might have encountered problems with the basic authentication feature in your configuration. This can be frustrating, especially when you depend on AKHQ for effective management of your Kafka setup.

In this guide, we will go through the common issues you might face when configuring basic user authentication in AKHQ. Then, we'll provide a revised configuration that should solve your problem.

Understanding the Problem

Users have reported that their configurations containing the basic authentication tag are not functioning properly. In particular, they encounter errors when attempting to log in to the AKHQ user interface.

Common Problems Encountered

Errors during login attempts: For instance, exceptions such as javax.naming.PartialResultException: Unprocessed Continuation Reference(s) might appear in your logs.

500 Status Errors: This is a server error that often indicates issues with your configuration settings.

Here's a snippet indicating an error logged during the authentication attempt:

Having identified the symptoms, let's explore how to fix them.

Revised AKHQ Configuration

To remedy the situation, you need to ensure that your application-dev.yml file is correctly structured and includes the necessary security settings. Below is a suggested updated configuration that resolves the common authentication issues:

Key Changes Made

Enabled Security Module: The security segment is explicitly set to true.

Allowed Origins: Updated allowed origins in the CORS configuration to match where you will be accessing the UI (for example, http://localhost:3000).

Basic Authentication Structure: Properly structured the basic-auth section and ensured the password is hashed (SHA-256).

Conclusion

After implementing the above changes and rebuilding your configuration file, you should find that the basic authentication feature in AKHQ works as expected. Testing your configuration by logging into the UI should yield success without throwing errors.

If you encounter further issues, carefully review the logs for any new error messages, as they can provide insight into misconfiguration or other potential problems.

With consistent monitoring and correct setup, you can leverage AKHQ to manage your Kafka infrastructure effectively!
