[Samba] Any advice for installing Samba as an AD server on Raspbian Buster with BIND9 and ISC DHCP?

Thanks for your advice, Rowland

Yes - joining a new DC to an existing domain.

That's what I was wondering... I'll do the join first with the internal Samba dns server
then upgrade it to bind9_dlz.

My dhcpcd.conf specifies a fixed ip for eth0, but I don't really know how well it will play with 
bind9 and samba.
I think I'll take your advice here.

I'm also worried the resolv.conf is getting rewritten and I think I'll
want to edit that one manually as well for bind9 and samba, correct?

If I remember right from the last time I set up Samba (a few months ago) some of the folder 
locations didn't reflect the newer locations that Samba now uses to simplify file premissions 
for the bind9 user account, but this might be fixed now.
(BTW, https://wiki.samba.org/index.php/Setting_up_a_BIND_DNS_Server refers to this user 
as both 'bind' and 'named'. I think named is the one I saw bind9 using when installed.)

I'll try to note specific things in the wiki that seem out of date or confusing as I proceed and 
let you know.

Louis's how-to really helped me out when I installed samba on Ubuntu.
I'll try to write up my own notes for Raspbian as I go...

These are the packages Louis installs on Ubuntu - are they best for Raspbian, also?

# The Samba 4.11 package for Raspbian on Louis's site....
apt install samba winbind krb5-user
#(optional must often used so install it. )
apt install libnss-winbind  libpam-winbind
#for the time sync in samba we need ntp or chrony. 
#Prepare time ( I preffer ntp.) 
apt install ntp
#Prepare DNS ( I preffer bind9 )
apt install bind9
# and add some tools you might need.
apt install binutils ldb-tools smbclient 
apt install libpam-krb5

Anything missing here?
