    Remote Access Software Version 5.3 Release Notes

Since the features now enabled by default consume a significant amount
of memory, you may want to disable those that you do not use. To do so,
use the Annex parameter disabled_modules.

Release 5.1 includes an embedded RADIUS client. This feature enables
you to use a Remote Annex or RAC in conjunction with the following
RADIUS servers:

•

Any shipping BSAC server

•

Livingston 2.01

•

Ascend 22497

•

Merit RADIUS 2.4.23C

RADIUS is an IETF-developed protocol that defines a communication
standard between a Network Access Server (NAS), a Remote Annex or
RAC in this case, and a host-based communication server.

RADIUS operates in three modes:

•

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 the
authentication modes PAP (Password Authentication Protocol),
CHAP (Challenge Handshake Authentication Protocol), and
user name/password validation. Authorization is sent back to the
client by the server.

•

RADIUS Accounting defines a communication standard
between a NAS and a host-based accounting server. It records
duration of service, packet throughput, and raw throughput.

The lat_key parameter must be set in order to enable LAT.
