Be aware that being able to replicate to Samba doesn't mean you can
replicate from Samba. We may still have bugs with replicating back
objects written with the 2012R2 schema loaded, but it could be better
with 4.4rc5 than it has been in the past. (I've fixed some bugs in
this area, but I think there is still work to be done).
