Using RADIUS to Authenticate Users
This section provides a description of RADIUS and explains how to configure PortServer TS 8/16
to use RADIUS.
What is RADIUS?
RADIUS (remote authentication dial-in user service) is a method of maintaining a database of
profiles of dial-in users. These profiles can include login and password information, as well as other
user attributes.
RADIUS Components
RADIUS requires two components, an authentication host server and client protocols. The
PortServer TS 8/16 implements the client protocol. A host must implement the authentication server
application.
