You're unhelpful. I know that I can chown as nobody because I changed
it because I changed it on my own as I already said multiple
times. Now I want to know why I cannot chown a file in a mounted
directory but can do that on the server as *the same* user.

I had the second thought that it may not be related to Samba but to
how cifs module works on Linux general because as strace shows
lchown() is finally done but it fails.

I'm just looking for hints.
