AGDLP (an abbreviation of "account, global, domain local, permission") briefly summarizes Microsoft's recommendations for implementing role-based access controls (RBAC) using nested groups in a native-mode Active Directory (AD) domain: User and computer accounts are members of global groups that represent business roles, which are members of domain local groups that describe resource ...
