1909
1910           On a Windows share, a file with read-only dosmode can be opened with
1911           DELETE_ACCESS. But on a Samba share (delete readonly = no), it
1912           fails with NT_STATUS_CANNOT_DELETE error.
1913
1914           This semantic causes a problem that a user can not
1915           rename a file with read-only dosmode on a Samba share
1916           from a Windows command prompt (i.e. cmd.exe, but can rename
1917           from Windows Explorer).
