Then restart samba on the DC and re-try joining the domain after deleting all files /usr/local/samba/private on the DC I am attempting to join to the domain as a DC?

Did you ever get to the bottom of this?  I'm working on a patch for this
issue because I'm worried about a broader corruption that this may or
may not be related to.  Did you ever run Samba from GIT or a 4.1
