I'm a little new to OpenVPN. I'm trying to get google authenticator to work with OpenVPN but I'm having a little trouble. Currently I'm tring to setup a radius server to run the authentication then have the radius server use google authenticator as part of the authentication process. I feel like there has to be a better way to do this. If anyone has done this before or knows a better way to go about it some guidance would be much appreciated.
There is an extention made for OpenVPN for OTP (One Time Password). This extention includes Google Authenticator software tokens.
