share permissions security issue

[David Baker]

I have Samba 2.2.8a on a Red Hat 8 box.  My smb.conf file is below.  I
have the PDC functionality working.  The login script works fine.  Each
user can create directories and files in their own folder and the public
folder.  What I need to be able to do is have a user create a directory
in the Public folder and then set specific permissions on that folder so
that some users will be able to read or write or whatever combination of
security options.  From what I read in the HOWTO documents this should
work.  However, when I create a folder and then try to add a user with
permissions of, let's say, read only and then try to save it, I get an
error that permission is denied.
 
Can anyone help?  Thanks a thousand-million.
