I am not sure when OpenVPN added multi-factor support to their Access Server but I am thrilled that they did. It must have been recently (within the last few weeks or months) as I was using OpenVPN Access Server about 4 months ago as a temporary solution while my main solution was down and it did not have Multi-Factor built-in. All I have to say is, THANK YOU! (more…)

After having already gotten a full page into writing a walkthrough (not to mention hours already spent with Authy) I found out that Authy will NOT WORK with OpenVPN and LDAP authentication unless the folks at Authy customize the ldap module for you. Which requires enterprise support, at a retail price of $500/month! Which was quoted to me at a “discounted” rate of $350/month. I really appreciate what the folks at authy are trying to build and they have a decent product on their hands but it was a bit frustrating that they advertise working LDAP authentication when in fact it requires their dev team to get in and hack the code for you. I am now trying DUO with OpenVPN Access Server and hoping for better results… This is not going to be free but will at the least only run us somewhere between $75 – $350/ YEAR… considerably more affordable…

INTRODUCTION

I wrestled with getting OpenVPN to work with Microsoft Active Directory authentication better part of 2 days. I was surprised that it was so hard to find a straightfoward tutorial on the topic that actually worked! I had to do a lot of Google-Fu and look at many different pages to put together what I needed to get this done. So… to hopefully save myself and others some future headache. I endeavor to put most of it all together here. This guide assume a few things about the audience though that you should know up front…
