Assunto: Re: [DNG] How to force permission change
In all of these remote storage situations the host where the storage
resides overrides everything else. Root on a client box is no different
than any other user on the client box, they have whatever permissions that
the storage host gives them or allows them to change and no more. That
implies that the first place to look for this kind of problem is on the
host where the files reside, so that is the first thing I thought.

There are more issues in the difference between Windows or cifs and Linux
permission and authority styles, they rarely translate well.

When I build a Nas box I usually the Linux operating system and export the
storage multiple ways, one of those being shamba.

I am not sure if that helps, but it gives you another approach.
