The PowerShell Podcast

Active Directory meets source control with Fred Weinmann

Andrew sits down with Fred Weinmann, one of the most prolific PowerShell module authors in the community, for part one of a multi-episode series covering his projects. This episode focuses on the Active Directory Management Framework, or ADMF, a configuration-driven system Fred originally built while working as a field engineer at Microsoft for a large enterprise customer managing hundreds of Active Directory forests.

Fred walks through the problem ADMF was designed to solve: Active Directory is notoriously hard to manage consistently across environments, and most organizations just accept the chaos as the cost of doing business. The old approach at this particular customer involved zipping up scripts, RDPing into domain controllers, and running them manually. ADMF changed that by borrowing the test/apply concept from Desired State Configuration, but making it flexible enough to handle the messiness of real-world AD environments.

The conversation covers how ADMF is structured around components (like organizational units) and contexts, why generating a reference configuration from an existing environment is harder than it sounds, the protocol juggling required to handle Group Policy and schema updates, and why Fred would use raw LDAP instead of the built-in AD commands if he were starting from scratch today. Fred also touches on the credential provider plugin system, which lets teams plug in their own password management workflows for things like break-glass accounts.
