Hello Rowland,
Thank you very much for your support so far.
Now I could join.
But:
Now I have a problem with the DNS. I use the samba internal DNS.
When I try to reach mydom.local or SAD.mydom.local, I only get the error:
nslookup SAD.mydom.local
Server: 192.168.159.98
Address: 192.168.159.98 # 53
Non-authoritative answer:
*** Can not find SAD.mydom.local: No answer
--------------------------------------
nslookup mydom.local
Server: 192.168.159.98
Address: 192.168.159.98 # 53
Non-authoritative answer:
*** Can not find mydom.local: No answer
a nslookup on google.de works. (I added the following entry to smb.conf: dns forwarder = 8.8.8.8)
Also, I can not address the Samba server with the Windows DNS Tools: The Active Directory is not available.
in the jornalctl I have the following messages:

Do you have an idea for this?
Currently Samba 4.7.6 is still installed.

Anything after this point is an artefact of the failure and can be ignored.

You are getting closer, the join is now failing at the last hurdle and we had this very recently with a user trying to join to Windows 2003 DC.
The cure was to stop the join creating the DC records.
Find 'join.py (/usr/lib/python2.7/dist-packages/samba/join.py on my DC) and open it in your favourite editor, find these lines:
if ctx.dns_backend != "NONE":
ctx.join_add_dns_records()
ctx.join_replicate_new_dns_records()
Line 1405 in my version, under ' def do_join(ctx):'
just comment out those three lines, save & close, then try the join again.
