RADIUS is an IETF- developed protocol that defines a communication
standard between a Network Access Server (NAS) and a host-based
communication server. RADIUS modes are as follows:
• RADIUS Authentication includes authentication of the
dial-up user to the RADIUS server, as well as authentication
of the RADIUS server to the NAS. RADIUS supports
authentication modes PAP and CHAP (Challenge Handshake
Authentication Protocol) .
• RADIUS Accounting, another IETF-developed protocol,
defines a communication standard between an NAS and a
host-based accounting server. It records duration of service,
packet throughput, and raw throughput.
• Although RADIUS Authorization is not supported in this
release, Authorization is addressed by the Access Control
Protocol (ACP). Authorization of the acp_userinfo,
acp_restrict, and acp_dialup files still apply to users that
are authenticated through RADIUS.
