Project Summary
FreeRADIUS is an open source RADIUS server. The server scales easily from embedded systems with small amounts of memory to systems with millions of users.
It is fast, flexible, configurable, and supports more authentication protocols than most commercial servers. It includes support for SQL, LDAP, RADIUS Proxying, failover, load balancing, and nearly 100 vendor dictionary files. It can perform authentications via the PAP, CHAP, MS-CHAP, EAP-MD5, EAP-GTC, EAP-TLS, EAP-TTLS, PEAPv0, LEAP, EAP-SIM, and Digest authentication protocols.
