[Samba] Date and Time change on unchanged Office files ...

[f.pospischil at telenet-ag.de]

... when you are not owner of an Excel or Powerpoint file, the 
modification time will change to now() even when nothing is changed.
The same was true for Word before i set "dos filetimes" and "dos filetime 
resolution" to yes.

How can I prevent files from getting "brand new" by only viewing them ?
"Force user" is not a really good idea, as we need ACL support to 
implement a strict user rights concept.

Any ideas ?

(BTW, the lack of NTFS file system tunnelling doesn´t seem to be the cause 
of these problems. I did some testing on a NTFS-Volume on a Server with 
this "feature" turned off.
the change of filetimes did not occur ...)

Thanks in advance ...
