Automating OpenID Connect-Based AWS IAM Web Identity Roles with Microsoft Entra ID

This article discusses automating the process of setting up OpenID Connect-based AWS IAM Web Identity Roles with Microsoft Entra ID for machine-to-machine authentication and authorization.

Specifically, the article covers:

• The manual steps involved in creating an application in Microsoft Entra ID, configuring an OpenID Connect provider in AWS, and integrating an IAM Web Identity Role
• Challenges with manual setup in enterprise environments, such as violating security policies, requiring deep understanding of both platforms, and needing substantial access privileges
• An automated solution using AWS Step Functions and Lambda functions to synchronize Microsoft Entra ID service principals and AWS IAM Web Identity Roles across an AWS Organization
• Conclusion: This approach allows centralized management of users in an enterprise identity provider while providing secure access to AWS resources for machine-to-machine authentication
