FreeRADIUS is a modular, high performance free RADIUS suite developed and distributed under the GNU General Public License, version 2, and is free for download and use. The FreeRADIUS Suite includes a RADIUS server, a BSD-licensed RADIUS client library, a PAM library, an Apache module, and numerous additional RADIUS related utilities and development libraries.[1]
In most cases, the word "FreeRADIUS" refers to the free open source RADIUS server from this suite.
FreeRADIUS is the most popular open source RADIUS server[2] and the most widely deployed RADIUS server in the world.[2] It supports all common authentication protocols, and the server comes with a PHP-based web user administration tool, called dialupadmin. A new implementation of a web application for freeradius made in Ecuador called SAAAS!. It is the basis for many commercial RADIUS products and services, like embedded systems, RADIUS appliances that support Network Access Control and WiMAX. It supplies the AAA needs of many Fortune-500 companies, telcos and Tier 1 ISPs. It is also widely used in the academic community, including eduroam. The server is fast, feature-rich, modular, and scalable. The server has reached a stable version 2.1.11, with incremental improvements added in every release.

FreeRADIUS was started in August 1999 by Alan DeKok and Miquel van Smoorenburg. Miquel had previously written the Cistron RADIUS server, which had gained widespread usage once the Livingston server was no longer being maintained. FreeRADIUS was started to create a new RADIUS server, using a modular design that would encourage more active community involvement.
Modules included with the server core support LDAP, MySQL, PostgreSQL, Oracle, and many other databases. It supports all popular EAP authentication types, including PEAP and EAP-TTLS. More than 100 vendor dictionaries are included, ensuring compatibility with a wide range of NAS devices.
Version 2.0.0 added support for virtual hosting, IPv6, VMPS, and a new policy language that simplifies many complex configurations.
A survey in 2006 showed that its user base totals 100 million people.[2]
