RADIUS and ACP Protocol Operation

RADIUS and ACP servers work together to provide the user with a
standard means of communication between a Network Access Server and
a host-based server.
When or If...
the security profile matches the
Server Tools Options dialog box
RADIUS on/off toggle switch,
the user name and password are
entered correctly,
the Access-Accept, Access-
Reject, or Access-Challenge
packet fails to arrive in the
specified amount of time,
no response is received,
ERPCD/ACP receives an
Access-Accept packet,
ERPCD/ACP receives an Access-
Reject or an unsupported Access-
Challenge or the backup
RADIUS server also fails to
respond,
The...
expedited remote procedure call
daemon (ERPCD)/ACP prompts the
Remote Annex for the user name and
password.
ERPCD/ACP sends a RADIUS Access-
Request packet to the RADIUS server
(this packet contains the normal
RADIUS header and the Access-
Request attributes).
ERPCD/ACP re-sends the packet.
ERPCD/ACP sends the Access-
Request packet to the backup RADIUS
server, if configured in the Server Tools
Options dialog box.
ERPCD/ACP considers the user
validated.
ERPCD/ACP considers the user
invalidated.
