[Samba] dos filetimes and documentation

[Thorsten Greeb]

The smb.conf documentation and also the HowTo-Collection describes, that
with dos filetimes = Yes any user with write permission is able to
change the file timestamp. This seems to be not fully correct. What we
found is, that not only the user must have write permission but also
must be a member of the owning group if the user is not the owner of the 
file. Could anyone of the samba folks clarify this?
