title: Set executable permission from Windows host on Linux filesystem
body: <p>I have a python script which runs on a Windows machine. On this machine I have mounted a Samba filesystem (on a Linux host).</p>
  
  <p>When I now try to change file permissions on the filesystem with <code>os.chmod(S_IXUSR)</code> it doesn't set the excutable permission, since it is hardcoded in Windows to not do anything as some research I did suggests. </p>
  
  <p>Do I have any chance to change unix file permissions from a Windows host using python?</p>
