I'm suspecting that the LDB errors above are the cause, not the ACLs in
this case.  This particular check tries to set an ACL top-to-bottom to
ensure it all works.  I had something like this recently, but wiping the
prefix and a fresh install fixed it.  That isn't very satisfying,
because I like to know how this can happen, but this may help you get
out of this spot.

(I don't normally recommend reinstalling Samba, as it normally changes
nothing and only wastes time). 

I hope this helps in some small way.
