Disabling the setting will mean that the user will be logged out if the RADIUS accounting server
cannot be reached even though the user has been previously authenticated.
Default: Enabled
Logout at shutdown
If there is an orderly shutdown of the D-Link Firewall by the administrator, then NetDefendOS will
delay the shutdown until it has sent RADIUS accounting STOP messages to any configured
RADIUS server.
If this option is not enabled, NetDefendOS will shutdown even though there may be RADIUS
accounting sessions that have not been correctly terminated. This could lead to the situation that the
RADIUS server will assume users are still logged in even though their sessions have been
terminated.
Default: Enabled
Maximum Radius Contexts
The maximum number of contexts allowed with RADIUS. This applies to RADIUS use with both
accounting and authentication.
Default: 1024
