Why did you install the 'recommended' packages ????

You seem to using the internal dns server

You cannot run ctdb on a Samba AD DC

smbldap-tools is for an NT4-style PDC

ufw is a firewall

glusterfs-common & libcephsfs1 are for clusters

in fact, the only one you 'might' need is ldb-tools

Now we come to your fix, Bind9 is running on port 53 and blocking your 
DCs internal dns server.
