OK I decided to write this up after unsuccessfully being able to find all the required info I needed in one place. In this setup we will be using Ubuntu Server 22.04.2 LTS as the OS. I have this running on a home lab ESXi server 8, on a HP Compaq Pro 6300 SFF CPU = Intel Core i7-3770 Installed Memory 16 GB I have some 10K SAS drives installed for the VM's If you have not already, navigate to  Get Ubuntu Server | Download | Ubuntu and download the 22.04.2 LTS ISO Next Lets create our VM that we are going to run this in. *Note Im using ESXi however you can probably do this in Workstation, Fusion, VirtualBox etc The main things to note on the VM creation. Set Ubuntu 64 bit as the guest OS Set your CPU relevant to the physicals CPU, I will be starting with 4 VCPU Set your Memory to as much as you can tolerate, I will be using 12 Disk Space - we are creating a 100G swap file, and the rest of the file can take up some room , so more is better if you can afford it Dont forget to add the U...

Update 10/2017:  Since starting this project  I was informed that such a thing already existed , so I will not be moving forward with this. You can use LinOTP in your enterprise environment. As a continuation of my previous post I wanted to see if I could build a simple server to to allow users to generate google authentication keys, and authenticate to Horizon View.  After some research I was finally able to get a 'functional' server up and running and easily deplorable. No going forward please realize as I said before this is a PROOF OF CONCEPT, you should not deploy this in your production environment, you have been warned (See notes at the end of this page), however if you want something to mess around with to build your own , here ya go.
