freeradius

FreeRADIUS is a high-performance RADIUS server with support for:

  • Authentication by local files, SQL, Kerberos, LDAP, PAM, and more.
  • Powerful policy configuration language.
  • Proxying and replicating requests by any criteria.
  • Support for many EAP types; TLS, PEAP, TTLS, etc.
  • Many vendor-specific attributes.
  • Regexp matching in string attributes. and lots more.
