If you look here:
You will find 4.6.0 amd64 debs, Samba does not support 4.2.x anymore,
though this doesn't stop you using it.

You might as well remove those lines, they do not work on a DC (Also
please do not call your DC a PDC, it is confusing)

Winbind on a DC, does not extract the users unix home dir and login
shell, you have to use template lines in smb.conf.
