Use of Status-Server Packets in the Remote Authentication Dial In User Service (RADIUS) Protocol
FreeRADIUS
RFC 2865 defines a Status-Server code for use in RADIUS, but labels it as "Experimental" without further discussion. This document describes a practical use for the Status-Server packet code, which is to let clients query the status of a RADIUS server. These queries, and responses (if any) enable the client to make more informed decisions. The result is a more stable, and more robust RADIUS architecture.
