[Samba] Error copying dot-files to samba share

Hi all,

I'm having a problem copying (overwriting) a dot file to a samba share.

When I create a dot file (e.g .project) on a local drive at the XP
machine, I'm able to copy the file to the share ONLY if it does not
exists there. If the file already exists, Samba refuses to overwrite the
file.

The reason of this behavior must have something to do with "hide dot
files = yes" and also "map hidden = yes". Both parameter are enabled in
my smb.conf. If I set one (or both) of these 2 parameters to no,
overwriting of the dot file works.

It also works, when I change the dos attribute of the dot file to
hidden, before copying to the share.

It must have something to do with the check of appropriate rights in the
 functions open_match_attributes and open_file_ntcreate in smbd/open.c.

Thanks,
Thomas
