I'm a total beginner trying to set up a connection to Amazon DocumentDB and I have a question. I found this AWS document that has an example for connecting with TLS enabled using Node.js, but it only shows a sample username and password. I want to connect using IAM authentication instead, which I've already enabled, but I'm unclear on how to do this programmatically. Is there a specific way to structure the connection string for IAM authentication, especially when using TLS? I've tried using AI tools for help, but they haven't provided useful answers.

For connecting using IAM, you generally need to set the connection properties properly in your code. If your team is not using the mongoClient class, that could be a hurdle. Have you referred to the connection string format that includes the proper IAM role? Make sure your application has the necessary AWS SDK packages as well.
You might find the AWS documentation on IAM identity authentication really helpful. There's a specific guide for using IAM roles and users to connect to DocumentDB, which could clarify what you need to do. Have you checked out the page on IAM identity authentication? It explains how to set it up, and you might need some specific configurations in your connection string.
I had a similar issue when I was starting out. Once I configured the IAM roles correctly and ensured my permissions were set, it worked for me. Just make sure that your users in DocumentDB are aligned with your IAM roles, as mismatches can lead to errors. If you're getting an Error 300, it might be because the credentials are not being fetched correctly, so double-check that aspect.
