How to add WiKID Two-Factor Authentication to a SonicWall VPN

A WiKID customer just added two-factor authentication to their a SonicWall VPN appliance setup and we took the opportunity to document the effort, which was extremely simple. More and more small companies are required to use two-factor authentication for remote access to corporate assets. A SonicWall VPN appliance combined with two-factor authentication from WiKID secures your perimeters in a very cost-effective manner. This document details how to configure a SonicWall VPN appliance to pass authentication requests to the WiKID server. If this is a new SonicWall VPN setup, test logging in without a WiKID one-time password before adding in two-factor authentication. It will make troubleshooting easier.

• First, on the SonicWall configure the RADIUS server settings.
• Log in to the SonicWall admin interface.
• Go to VPN window and go to the RADIUS tab.
• Configure an amount of retries and timeouts.
• Enter the IP address of the WiKID server.
• Enter the radius port. The default is 1812, which is what WiKID uses.
• Enter the shared secret that will be used on the WiKID server.
• Click Update to update the configuration.

• Now, enable RADIUS authentication with GroupVPN on the SonicWall server.
• Open the VPN window on the admin interface and choose the Configure tab.
• In the Security Association field, choose GroupVPN.
• Check the box that says Require XAUTH/RADIUS.

• Now, we'll add the second factor: WiKID.
• Log into the WiKID server and click on the Domains Tab
• Click on Create a New Domain
• Enter the information requested. The Domain Server code is the zero-padded IP address of the WiKID server. So, if the external IP address is 216.239.51.99, the WiKID server code would be 216239051099. Click "Create".
• Click Network Clients tab and on "Create a new Network Client".
• Enter the information requested. For the IP Address, use the IP address of your SonicWall VPN appliance. Select Radius and the domain you just created. Click "Add" when you're finished.
• On the next page, enter the shared secret you entered on the Sonic Wall server. You do not have to enter any information under "Return Attributes".
• Important: From the WiKID terminal or via SSH, you will need to run "stop" and then "start" to load the new configuration into the WiKID Radius server.

That should be it for setting up the SonicWall for two-factor authentication. Now, let's test the system by setting up user manually:

• starting the WiKID token client
• Select "New Domain" and enter the 12 digit domain identifier you set up on the WiKID server.
• Enter your desired PIN. You will get a registration code back from the WiKID server.
• Login to the WiKID Admin server again and click on the Users tab, then "Manually Validate a User"
• Click on your registration code (it should be the only one) and enter your desired username - it should be a username the SonicWall will accept.
• Your username is now valid. Now start up SonicWall VPN client and try to login with a WiKID one-time password.

If it doesn't work, check the WiKID server logs. When a one-time password is requested, you will see "Passcode Request Successful" in the logs. After that you should see "Successful Online Passcode Validation". If you don't see anything after the "Passcode Request Successful", then the OTP validation is not getting to the WiKID server from the SonicWall. Be sure to run "stop"/"start" on the WiKID server.

The WiKID Strong Authentication System is a very reasonably priced two-factor authentication solution. We invite you to learn more about our technology and architecture and to download and test the Enterprise version.
