RADIUS (Remote Authentication Dial-In User Service) provides authentication, accounting, and authorization functions, through a communications stream between clients and a dedicated server. NetMRI directly supports authentication and authorization using FreeRADIUS. Other widely used RADIUS implementations include GNU RADIUS and Microsoft IAS. RADIUS provides all user authentication in a single centralized database. After users are verified, they have access to any NetMRI administrative function permitted for their account.
