Hello list, I'm trying to get around old samba-users problem with common share used by many people. What I would like to achieve is to get all files in that share to belong to specific group. I was already trying the 'chmod g+s' way, but its not what I'm looking for, as this sets specific group only for newly created files and still gives possibility to change it later on (and it looks like Nautilus is chowning _after_ the file is created, as users still managed to add files with different groups using nautilus). Now I would like to forbid chowning files inside this share. This with connection with 'chmod o+g' should do what I need, but unfortunately I don't know how can I do this. Can anyone help with this? Thanks in advice. Notch
