I think your problems all stem from doing number 5 on your 'what I did'
list.

You do not want those users and groups in /etc/passwd and /etc/group,
they will all come from AD once it is working.

Also the 'netbios name' in smb.conf on your new DC must match the DCs
short hostname.

Have you read this:

I suggest you try again.
