Configuring RADIUS Authentication
To enable the SonicWALL security appliance to use authentication from a RADIUS server, follow
these steps:
1
Select Use RADIUS for user authentication.
2
Select Allow only users listed locally if only the users listed in the SonicWALL security
appliance database are authenticated using RADIUS.
3
Click Configure to set up your RADIUS server settings on the SonicWALL security appliance. The
RADIUS Configuration window is displayed.

In the Global RADIUS Settings section, define the RADIUS Server Timeout (seconds). The
allowable range is 1-60 seconds with a default value of 5.
5
Define the number of times the SonicWALL security appliance attempts to contact the RADIUS
server in the Retries field. If the RADIUS server does not respond within the specified number of
retries, the connection is dropped. This field can range between 0 and 10, however 3 RADIUS
server retries is recommended.
6
In the RADIUS Servers section, specify the settings of the primary RADIUS server in the RADIUS
servers section. An optional secondary RADIUS server can be defined if a backup RADIUS server
exists on the network.

The alphanumeric Shared Secret can range from 1 to 31 characters in length. The shared secret
is case sensitive.
