OK, I will change that to 'Do not use CTDB with Samba AD DCs'
A cluster is where all the same data is stored on multiple computers but
they act as if they were just one computer, which funnily enough is what
Samba AD dc's do, so you are wrapping something that acts like one
computer inside something that acts like one computer.
That is a very simplistic view of clusters, but I am sure you get my
drift, so I cannot recommend using CTDB with Samba AD DC's.

Your DC's really should have fixed IP's, I cannot recommend anyone using
