An administrator can configure authentication using the CLI utility and the web manager. The
default authentication method for the console server and the serial ports is Local. Any
authentication method that is configured for the console server or the ports is used for
authentication of any user who attempts to log in through Telnet, SSH or the web manager.
Appliance authentication
The console server authenticates for the console server and the ports, either in groups or
individually.

When Single Sign-on Authentication is disabled, the console server uses the individual
configuration based in the destination of the access: the console server itself or each serial port.
Users must use their password each time they access an individual port. If enabled, Single Sign-
on Authentication will use the authentication server you choose from the pull-down menu for
all access and no further authentication will be needed.
