[Samba] smb.conf setting for file permissions?

[Mike Eggleston]

Hi,

I have a very old version of samba on one of the boxes I'm not allowed
to update. I have a request from a user group that all the group be
allowed to edit a set of file. At the command line I 'chmod 666 $file'
and all is well. I can edit and save the file. The permissions return to
744. I want the file permissions to not be changed when someone saves
a file. What parameter can I add to /etc/samba/smb.conf so that file
permissions are not changed when a file is save?
