AAA server

The AAA server, also known as RADIUS server, provides end-users and devices Authentication, Authorization and Accounting. It is specially necessary to manage who or what users or devices have access to the network and which kind of service should the network provide them.

Currently, AAA servers communicate using the RADIUS protocol, that is why they are also known as RADIUS servers. However, future AAA servers are expected to use a successor protocol to RADIUS known as Diameter.

One of the most widely deployed RADIUS server in the world is FreeRADIUS. Some successful examples of its usage include many Fortune-500 companies, Tier 1 ISPs and eduroam. FreeRADIUS includes a RADIUS server, a BSD licensed client library, a PAM library, and an Apache module.

FreeRADIUS

In this section we are going to explain how to install and configure FreeRADIUS. Currently, version 3 of FreeRADIUS is available. However, in the repositories of Debian 7.5 there is version 2.1.12 already prepared.
