Synchronizing Entra users with VMware SAML authentication was a challenge I knew I had to solve. The traditional approach required deploying an on-premises SCIM solution or connecting vCenter directly to Entra, both of which introduced unnecessary complexity and potential security risks. I wanted something simpler, more efficient, and secure. That’s where the idea for the PowerShell Entra Sync Agent was born.
This tool was designed to bridge the gap between Entra and VMware without relying on SCIM or direct connectivity. By leveraging the Microsoft Graph API and the vCenter API, I created a lightweight solution that dynamically synchronizes users from a specified Entra group to VMware SAML authentication. It’s a solution that not only simplifies the process but also enhances security and scalability.
The core of the solution lies in its ability to automate and streamline. The PowerShell script I developed queries the Microsoft Graph API to retrieve users from a specific Entra group. It dynamically handles user additions, removals, and updates, ensuring that VMware always has the correct set of users. On the VMware side, the script communicates with the vCenter API to manage SAML users and roles, making sure everything stays in sync.
Challenges
One of the key challenges I faced was avoiding the need for additional infrastructure like SCIM. Instead, the script operates securely using API tokens and encrypted communication, making it lightweight and easy to deploy. It’s also designed to run on a schedule, so user synchronization happens automatically without manual intervention.
This project wasn’t just about solving a technical problem—it was about creating a solution that fit seamlessly into the organization’s existing workflows. I worked closely with IT and security teams to define requirements and ensure the solution met their needs. Testing was rigorous, with extensive validation in a controlled environment to ensure reliability and security.
Results
The results were transformative. By eliminating the need for SCIM or direct vCenter-Entra connectivity, the Entra Sync Agent reduced complexity and infrastructure requirements. It also improved security by leveraging secure APIs and avoiding direct exposure of vCenter to external systems. And because the solution is fully automated, it saved time and ensured accuracy, making it a scalable option for other groups or environments.
Looking back, this project was a testament to the power of automation and API integration. It reinforced my belief that even complex IT challenges can be solved with the right combination of creativity, collaboration, and technical expertise. The Entra Sync Agent is more than just a tool—it’s a reflection of my ability to design and implement innovative solutions that make a real difference.
