samba - Nov 2021 - Potential inconsistency in Samba DNS server when used with `samba-tool domain join`

I think there might be a problem with using `samba-tool domain join` to 
join a domain, as I've noticed some inconsistencies in whether or not 
the new client is picked up by DNS. Presently:

root at atomsmasher:~# net ads leave -U Administrator
Password for [EA\Administrator]:
Deleted account for 'ATOMSMASHER' in realm 'EA.LINUXCS.COM'


But

root at samba-dc:~# host atomsmasher
atomsmasher.ea.linuxcs.com has address 192.168.1.82

root at samba-dc:~# samba-tool computer list
DATA2$
IBS100$
SAMBA-DC$


How do I get the machine out of the Samba DNS so that I can see if what 
I observed previously is repeatable? I noticed I didn't have a DNS entry 
for this host, so left and rejoined the domain using samba-tool several 
times, never getting a DNS entry for it.  Then I joined using `net ads 
join` and it was in DNS immediately. I want to see of this is repeatable.

I might have to abandon Samba DNS and install bind as per Louis' 
recommendation.  I'm finding the Samba DNS to be hard to work with since 
there doesn't seem to be any way to interact with it directly.

host atomsmasher name resolving (dns) 
samba-tool computer list (name resolving AD-objects) 
2 different things.

If you use the windows tools, you dont see the computer untill you refresh. 
With samba tool :
sudo samba-tool dns query YOUR_AD-DC_HOSTNAME(.FQDN) primary-dnsdomainname
NAME2CHECKOUT A -UAdministrator

So for you : sudo samba-tool dns query samba-dc ea.linuxcs.com atomsmasher A
-UAdministrator
