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…

The company I work for is a relatively small shop when it comes to virtualization and especially when it comes to Hyper-V. So that means I am usually working on individual host servers and not doing any kind of grand scale configuration using SCCM or some other enterprise level tool. I think most folks in small-to-medium size businesses with existing infrastructure probably have a similar “use-case scenario” when it comes to Hyper-V.

We use Hyper-V primarily for development and test servers and often enough I get asked to deploy new servers. Now, the way I used to go about doing this was to create a new blank server, new empty VHD file, insert Server 2012 (or 2008 R2 or whatever…) CD/DVD ISO file and install from scratch. In this case, the actual install isn’t all that bad. Server 2012 particularly installs quite quickly. However downloading and installing all of the bloody Microsoft updates can take hours, tack onto that configuring the server for our environment and well, it gets to be a couple hours of work at least.


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…
