5.4.7 RADIUS
From the Admin menu in the Home screen, click on RADIUS. The screen shown in
Figure 5-13 appears.
Figure 5-13. RADIUS Configuration screen.
The RADIUS server requires the IP address, the UDP port number (1812, default or
1645) and the shared secret. The shared secret is used to encrypt communications
and corresponds to a shared password for the RADIUS server and the client
machine. Two additional servers may be defined for backup purposes. Each server
will be tried in order, using the indicated number of retries and timeout period,
which are configurable on the same page. Remember to enable RADIUS after
configuring it. While RADIUS authentication is enabled, the locally defined IP
module accounts on the ServSwitch will not be used, except for the SSH login.
However, if a username of the form “name.local” is given at the RADIUS prompt,
the system will use “name”; check the password locally, and skip RADIUS authen-
tication. Delete all local accounts to avoid this behavior. When connecting via
VNC, a login screen is generated that asks for a RADIUS username and password.
Table 5-7 describes the options in Figure 5-13.
