Not a typical topic for the Active Directory blog, but MVP Sainath K E V contributed a TechNet Wiki article titled: System Center Orchestrator Security on the TechNet Wiki. The article addresses the question of "How is the Security managed with Orchestrator?" You can check out the article and feel free to contribute to it on the TechNet Wiki. I see that Ed Price has already done something to it. 🙂 We appreciate the community contributions Sainath!
