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.
We provide a step-by-step guide to
radiusd -X. The guide breaks down the different pieces of the debug output, and explains what they mean. Often you can just look for ERROR or WARNING to solve many problems.
FreeRADIUS is responsible for authenticating one third of all users on the Internet.See why we're #1
