[Samba] Error joining Samba 4.7.4 DC to existing Win2008R2 domain

I have an existing Win2008-R2 domain with a single DC and I'd like to 
replace this DC with a Samba 4 DC.

I'm using VirtualBox VMs to test the migration before going to production.
I've cloned Windows 2008R2 Server into the first VM, then installed 
Ubuntu_18.04_server_x64_daily (Samba 4.7.4) into another VM.

Win2008-R2:?? hostname=SRVAD-OLD, IP: 10.0.3.90
Ubuntu_18.04: hostname=SRVAD-NEW, IP: 10.0.3.100

The two machines are connected to the same virtual network and can ping 
each other.

Now, when I run samba-tool to join the domain, the join fails with this 
error:

=====================================================root at srvad-new:~# samba
-V
Version 4.7.4-Ubuntu

[Samba] Error joining Samba 4.7.4 DC to existing Win2008R2 domain

On the Windows DC can you check that the A record is actually created?
> Adding DNS A record SRVAD-NEW.SAMDOM.LOCAL for IPv4 IP: 10.0.3.100
It appears that the record is added over RPC, but then fails to find it
over LDAP. Presumably they are to the same domain controller, so you
should be able to see if there is a record in the domain DNS zone. Maybe
there is a race here, but that seems a little unlikely. Alternatively,
it might be storing the record in a place we do not expect. Try with
some additional debugging perhaps, using -d3 for instance and see if
there's any more detail on the DNS error.

Cheers,

Garming

[Samba] Error joining Samba 4.7.4 DC to existing Win2008R2 domain

Thanks for your help.
> On the Windows DC can you check that the A record is actually created?
Yes, it is, and it persists after join failure.
Another sign of presence of SRVAD-NEW on the old DC is the new computer 
account, created in "Domain controllers" folder in "Active
Directory
Users and Computers" at the beginning of join procedure then 
automatically removed just after the failure message.

 > Try with some additional debugging perhaps, using -d3

That's exactly what I meant with "shed some light"... that option
should
be mentioned in the "Joining a Samba DC to an Existing Active

Wikipage ;)

Here's the new log:

This caught my attention, but I don't know how to fix it:
==Could not find machine account in secrets database: Failed to fetch 
machine account password for SAMDOM from both secrets.ldb (Could not 
find entry to match filter: 
'(&(flatname=SAMDOM)(objectclass=primaryDomain))' base:

Thanks again for your help.
