Configuration-specific User Group Settings
Also, to run password aging for transit sessions, the AAA client can be
running either RADIUS or ; and the AAA client must be using
Cisco IOS Release 11.2.7 or later and be configured to send a watchdog
accounting packet (aaa accounting new-info update) with the IP address of
the calling station. (Watchdog packets are interim packets sent periodically
during a session. They provide an approximate session length in the event that
the AAA client fails and, thereby, no stop packet is received to mark the end
of the session.)
You can control whether Cisco Secure ACS propagates passwords changed
by this feature. For more information, see
Local Password Management,
page 8-5
.
Cisco Secure ACS supports password aging using the RADIUS protocol under
MS CHAP versions 1 and 2. Cisco Secure ACS does not support password aging
over Telnet connections using the RADIUS protocol.
Caution
If a user with a RADIUS connection tries to make a Telnet connection to the AAA
client during or after the password aging warning or grace period, the change
password option does not appear, and the user account is expired.
