[Samba] Keeping file permissions on file overwrite

[Eddy Ilg]

Hi, 


I am trying to get a share on which new files will be created with 
-rw-r--r-- and permisisons on existing files will be kept. 
For example if I have a file with permissions -rwxr-xr-x 
then I want the file to keep these permission bits when it is overwritten 
from a windows editor. 


I have played with different mask/mode settings and the map archive 
setting, but when I edit a file from a windows Machichne and save it, 
the existing permissions are always overritten with the ones that 
a new file would have. If I open a -rwxr-xr-x file and then overwrite it, 
it has -rw-r--r-- bits. 


Can I tell Samba not to overwrite the permissions? 

Thanks
