====== Install OpenVPN Access Server ======

First, make sure that all of the latest patches are installed

<code bash>
sudo apt-get update
sudo apt-get dist-upgrade
sudo reboot
</code>

I run this on both Ubuntu 14.04 and 16.04 servers without any problems...

<code bash>
cd /tmp

wget http://swupdate.openvpn.org/as/openvpn-as-2.1.4b-Ubuntu16.amd_64.deb

sudo dpkg -i openvpn-as-2.1.4b-Ubuntu16.amd_64.deb

sudo passwd openvpn

sudo /usr/local/openvpn_as/bin/ovpn-init
</code>

  - In the initialization wizard:
    * Enter DELETE and press enter
    * Enter yes to accept agreement
    * Press enter to configure this server as primary Access Server node
    * Choose (1) all interfaces: 0.0.0.0 for the network interface
    * Select defaults for remaining questions.
  - Open a web browser and navigate to the Admin URL.
  - Log in with the OpenVPN user account
  - Once the Admin interface loads, change authentication (in the General tab) to local.
  - Finally, add users while checking "Allow Auto-login" for each user.

At this point, each user can log into the server to download the client and/or config file.
