[Samba] cutting corners (4.10.2 on el7.6)

Hi Garming,

Thanks for taking the time to enlighten me. I do happen to have two DC's 
and in my limited testing, 4.10.2 seems to function properly as an AD/DC 
on el7.6 with the packages I built. As I'm not using those DC's for file 
serving in a clustered setup, it is also my interpretation that I can do 
without ctdb (this one had a specific requirement for a higher version of 
a lib which I didn't have) for basic AD/DC functionality.

I've tested RSAT, drs replication, and 
basic functionality and that seems quite positive so far.

I've posted my rpms/srpms/spec files at: 

Kind regards,
