You still didn't provide any details about your particular situation
which triggers this problem.  Would you _please_ do that?

If is very hard to conduct a meaningful discussion without a clear
understanding of the problem.  Maybe you are right in your analysis,
but without actually seeing the ACLs of the related directories, we
cannot be sure that your analysis is correct and complete.  Given the
details, we could reason about the problem and maybe consult with some
experts if the knowledge we have here is insufficient.  That would
make this discussion much more productive, and a satisfactory solution
will probably be found quickly enough.

Thanks in advance.
