Do this...
If your organization uses RADIUS realms, type the realm to append to
RADIUS requests. The realm will be appended to the username as
follows: <username>@<realm>
For example, if you set the realm to "myrealm", and the user "JohnS"
attempts to log on to the UTM-1 Portal, the UTM-1 appliance will send
the RADIUS server an authentication request with the username
"JohnS@myrealm".
This field is optional.
Type the interval of time in seconds between attempts to communicate
with the RADIUS server.
The default value is 3 seconds.
If the RADIUS VSA (Vendor-Specific Attribute) is configured for a user,
the fields in this area will have no effect, and the user will be granted
the permissions specified in the VSA.
If the VSA is not configured for the user, the permissions configured in
this area will be used.
