HP-UX AAA Server A.08.00.01 Administrator's Guide

1 Overview: The HP-UX AAA Server
The Remote Authentication Dial In User Service (RADIUS) protocol defines a standard
for information exchange between a network device or software application and an
authentication, authorization, and accounting (AAA) server to manage and track user
access to network services.
A RADIUS AAA server provides authentication (verifying user credentials),
authorization (supplying provisioning information for the user), and accounting (storage
of usage information into accounting logs) services to devices and software applications
(AAA clients) that support the IETF RADIUS standards.
The AAA or RADIUS client is the access device or application that acts as an enforcement
point to control access to a resource. The user device itself or application requesting
access to the resource is referred to as the supplicant.
