Initial Installation

 * Ubuntu 16.04 minimal https://help.ubuntu.com/community/Installation/MinimalCD
 * Static IP address
 * Guided partitioning with LVM
 * Only add OpenSSH server role

Basic additions
Ensure that ntp is able to see enough time sources. You could use use your AD DCs for example, especially the one with the PDC emulator role. The reference system uses the esxi hosts themselves as sources each of which have five external sources of time.

AD integration - Samba

 * Verify DNS and time.  See the example commands below.
 * Ping the AD name. You should be pinging a random AD DC based on your site.  This shows you have DNS set up correctly.
 * Check that time is in sync (examine the offset column in the output of ntpq -p) and that the timezone is correct
