Good one, i checked this. 

DC1  : 
dpkg-query -s python3-dnspython
Package: python3-dnspython
Status: install ok installed
Priority: optional
Section: python
Installed-Size: 618
... 

Same on all DC's. 


All run the following setting with netbios name changed offcourse. 
[global]
        netbios name = RTD-DC0
        workgroup = ADDOM
        realm = ADDOM.INTERNAL.TLD

        server role = active directory domain controller
        server services = -dns -spoolss
        idmap_ldb:use rfc2307 = yes

        # + A manual setup for TLS/SSL Certificates.
        tls keyfile = /etc/ssl/local/private/xxxxxxxxxx.key.pem
        tls certfile = /etc/ssl/local/certs/xxxxxxxxxx.cert.pem
        tls cafile = /etc/ssl/local/certs/xxxxxxxxxx-ca.pem

        template shell = /bin/bash
        template homedir = /home/users/%U

        load printers = no
        printcap name = /dev/null

        ntlm auth = mschapv2-and-ntlmv2-only

And the shares offcourse..  So nothing fancy. 

Other options? 

And thanks for the reply :-)
