AzMan - Windows Authorization Manager

AzMan is a role-based access control (RBAC) framework that provides an administrative tool to manage authorization policy and a runtime that allows applications to perform access checks against that policy. The AzMan administration tool (AzMan.msc) is supplied as a Microsoft Management Console (MMC) snap-in.
