Configure at least one RADIUS authentication server group. For more information, see Configuring a RADIUS Authentication Server Group below.
Define admin groups for the admins that are authenticated by the RADIUS servers and specify their privileges and settings. The group names in NIOS must match the admin group names on the RADIUS server. See About Admin Groups for information about defining admin groups.
In the authentication policy, add the RADIUS server groups and the admin groups that match those on the RADIUS server. You can also designate an admin group as the default group for remote admins. NIOS assigns admins to this group when it does not find a matching group for a remote admin. See Defining the Authentication Policy for more information about configuring the policy.

You can add multiple RADIUS servers to the group for redundancy. When you do, the appliance tries to connect to the first RADIUS server on the list and if the server does not respond within the maximum retransmission limit, then it tries the next RADIUS server on the list. NIOS tries to connect to each RADIUS server in the order the servers are listed. If it does not receive a response within the configured timeout period and has tried to connect the specified retry value, then it tries the next RADIUS server on the list. It logs an error to syslog when it fails to connect to any of the servers in the group.
After you add a RADIUS server to the NIOS appliance, you can validate the configuration. The appliance uses a
pre-defined username and password when it tests the connection to the RADIUS server. The pre-defined user name is "Infoblox_test_user" and the password is "Infoblox_test_password". Do not use these as your administrator username and password.
