samba - May 2010 - Preventing Windows from changing file permissions

Hi,?
Is there a way to configure samba such that Windows applications are not allowed
to change file permissions for existing files in the share.?
I just want to be able to read and modify the files from Windows without
affecting the file permissions inadvertently. I do not care about any Windows
side file attributes such as ACL.?
I tried several things including parameters such as 'map archive = no',
'security mask = xxx' etc. Nothing seem to result in what exactly I
want. This is surprising considering that my requirement is very simple.?
Is this possible in samba.?
thanks,Aneesh

You can always set "nt acl support = no", which is an old
option from when we first added Windows ACLs. Also setting
map XXX = no will stop DOS attributes being mapped to POSIX
permissions.
