When authentication is
enabled, the SCSI routing
instance passes the user name
and password from the iSCSI
driver to AAA for authentication.
AAA uses the authentication list
to determine which services to
use for the authentication
attempt. If authentication fails,
the connection is refused and
the IP host cannot obtain
access to storage resources.
