one authenticated user even though it may come from other users on the same network.
NetDefendOS RADIUS Accounting will therefore gather statistics for all the users on the network
together as though they were one user instead of individuals.
2.3.10. Advanced RADIUS Settings
The following advanced settings are available with RADIUS accounting:
Allow on error
If there is no response from a configured RADIUS accounting server when sending accounting data
for a user that has already been authenticated, then enabling this setting means that the user will
continue to be logged in.
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 NetDefend 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
