I've been following the whole process outlined at 
https://wiki.samba.org/index.php/Build_Samba_from_Source.  Of course, 
I've run update/upgrade.  I have already downloaded and executed the 
bootstrap script for Ubuntu 18.04 from the page you mention.  After 
this, ./configure starts with a large number of "NOT FOUND" warnings.  I 
traced those items down and installed them after the bootstrap.  Those 
unmentioned dependencies are included in the script I'm using to create 
and repeat the process when it fails.

libsamba-passdb.so is part of the samba source downloaded for the build 
process.  The error implies (to me) that one or more of the source files 
wasn't properly updated (I'd assume libsamba-passdb.so or files it 
depends upon) in the source package.  But I acknowledge that I'm a total 
noob at building from source.

Everything is run as root (the only user on a first-boot EspressoBin).  
This is part of a bash script-package repo I'm building on GitHub, which 
will allow a total Linux noob to take an EspressoBin straight out of the 
box and then configure it as one of multiple configurations.  The main 
script which installs Samba asks all of the necessary questions at the 
very beginning of the process.  It then allows the user to step away for 
a while (two-plus hours in the case of an AD DC, as it appears) as it 
installs and configures everything via silent install, altering 
configuration files and debconf-set-selections.  The script then assigns 
the user-entered password for root and creates a non-root sudo user with 
password.  A primary goal is to not have a single point of user 
interaction between the initial questions and the "all done" 

One of my goals with this script is to share my love of the EspressoBin 
and Linux with others.  I want this to allow more experienced users 
(like me) to take advantage of the hardware.  I also want to give 
less-advanced users the ability to poke around with the EspressoBin and 
Linux without feeling hopeless seeing all of the background information 
that is essential for installing and configuring a system and software 
like this.  The whole repo is built upon teaching users.  The scripts 
include almost as much commentary as executable code, explaining what 
nearly every command issued is doing and why it is needed.

I'd love to hear from Louis.  I love the RasPi and currently have eight 
of them performing a number of roles in my home computing environment.  
I switched to the EspressoBin for this project since it has USB3 
support, USB2 support, a SATA3 port, 3 gigabit network ports, with 
ethernet and USB NOT dramatically limiting each other.  Drive <-> 
network throughput is easily 6x on the EspressoBin vs. the RasPi, while 
still less than $100 US including SD card.  As a Samba file server, it 
dramatically outperforms my QNAP, which costs more than four times as
