I've found the fundamental cause of the major issues here.  There was
code that was looking for the string alpha9/10/... as an indication of a
modern Samba.  The attached patch, which is the top patch on the updated
tree above, changes the auto-detection to be a command line option.

With these patches, we no longer as badly corrupt a current provision.
We still need to avoid creating new objects under CN=Partitions
(duplicating the guid-based DNS partitions) in --full mode, and we need
to fix some more ACLs, but it's better than it was.
