[Samba] Replication Error Between Differing Samba Versions During Upgrade

Hello all-

At the recommendation of the Catalyst team, instead of trying to get 4.0.6
replicating with 4.0.7, they suggested we try a later version (>=4.5) as those
versions are much more recent and may have handled issues older versions just
could not. Unfortunately that too did not work. They then suggested that an
in-place upgrade, as if there was a bug in our 4.0.6 code that was causing
problems, there was not much else that could be done. The server survived an
upgrade from Ubuntu 12.04 (Samba 4.0.6) to Ubuntu 14.04 (Samba 4.3.11) with
minimal work afterwards (samba-dsdb-modules and samba-vfs-modules packages were
missing) and seemingly no loss of data.

We still plan on going up to 4.7 via SerNet packages or similar, but at
this point it seems we are out of the woods.

TL;DR - we fixed a replication issue that was blocking an upgrade by first
upgrading our existing hosts.
