You are having a hard time of it ;-)

Now, whilst I do not normally use Ubuntu, I know this does work.
My fellow Samba team member, Louis, has an howto here:

https://github.com/thctlo/samba4/blob/master/full-howto-Ubuntu18.04-samba-AD_DC.txt

Have a look at, it might point you at a possible error you made.

What documentation did you actually follow ?
