Welcome to the FreeRADIUS project, the open source implementation of RADIUS, an IETF protocol for AAA (Authorisation, Authentication, and Accounting).
The FreeRADIUS project maintains the following components: a multi protocol policy server (radiusd) that implements RADIUS, DHCP, BFD, and ARP; a BSD licensed RADIUS client library; a RADIUS PAM library; and an Apache RADIUS module.
FreeRADIUS is responsible for authenticating one third of all users on the Internet.See why we're #1
