History

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. As of November, 2014, the FreeRADIUS Project has three Core Team members: Alan DeKok (Project Leader), Arran Cudbard-Bell (Principal Architect), and Matthew Newton. The latest major release is FreeRADIUS 3. FreeRADIUS 3 includes support for RADIUS over TLS, including RadSec, a completely rewritten rlm_ldap module, and hundreds of other minor consistency and usability enhancements. The latest mature version is maintained for stability rather than features. The previous major release v2.2.x has entered the final phase of its lifecycle, and will now receive security fixes only A survey in 2006 showed that its user base totals 100 million people.
