[Samba] changing owner and group

[Marc Fromm]

Is there a way to prevent a samba connection from changing the file owner and group?
Users connect to the website on a linux box from windows desktops with Dreamweaver.
Each time a user edits a file that file's owner and group is changed from apache and developers to username and username, thus preventing other users from editing the file.
Can I set an option in samba to leave the owner and groups alone?

Thanks
