In the RADIUS Configuration dialog box, you can test your RADIUS Client user name, 
password and other settings by typing in a valid user name and password and selecting one of 
the authentication choices for Test. Performing the test will apply any changes that you have 
made.

To test your RADIUS settings:

In the User field, type a valid RADIUS login name.

In the Password field, type the password.

For Test, select one of the following:

Password authentication: Select this to use the password for authentication.

CHAP: Select this to use the Challenge Handshake Authentication Protocol. After initial 
verification, CHAP periodically verifies the identity of the client by using a three-way 
handshake.

MSCHAP: Select this to use the Microsoft implementation of CHAP. MSCHAP works for all 
Windows versions before Windows Vista.

MSCHAPv2: Select this to use the Microsoft version 2 implementation of CHAP. 
MSCHAPv2 works for Windows 2000 and later versions of Windows.

Click the Test button. If the validation is successful, the Status messages changes to Success. 
If the validation fails, the Status message changes to Failure.

To complete the RADIUS configuration, click OK.

Once the SonicWALL has been configured, a VPN Security Association requiring RADIUS 
authentication prompts incoming VPN clients to type a User Name and Password into a dialog 
box.
