It definitely appears to be the case that 4.0 should have been
provisioned with the correct link. It could have been some other bug
which meant it was lost somehow that we've probably fixed, or it was
accidentally deleted (or redirected in some way). I'm glad you were able
to identify the problem, Windows generally doesn't make it easy to debug
faults which occur during the join like this.
It seems to me that there needs to be a check in samba-tool dbcheck for
this perhaps (and maybe some of the other well known objects, if they're
that important). I don't suppose you have any interest in trying to do
that? Otherwise, file a bug for now.
