Creating two factor authentication is very easy to do with Client VPN Service. Here are the steps to take when needing to configure it:
WARNING: if you enable AD authentication, all existing users will need to re-download their VPN certificates as their existing certificates will no longer function.
Go to Network > VPN from the Control Portal menu.
From the VPN Configuration page, click the "edit settings" button. The VPN Settings popup will be displayed.
In the VPN Settings popup, set the fields as follows
- Max Connections - You are not billed by number of connections, so you may set to the maximum allowed if desired.

- AD Authentication - Make sure this is checked.
- Domain Controller IP - Specify the domain controller to do authentication on.

CN=openvpn_user,CN=Users,DC=domainname,DC=localwhich will allow

- User Location DN - Location of the domain to do the query on. Example: `DC=domainname,DC=local
