public share in samba
 

Cheers,

I have a samba public share in my server, and I've set the directory permission to 777. However, what I want is the following: everyone can read and write in the share, but only the creator of the file can change or delete it. How can I do it? My share is defined this way in smb.conf:

[public]
comment = Area publica da escola
path = /home/public
read only = no
public = yes

this must be easy stuff, pardon this newbie please, I need help.

set in smb.conf:

create mask = 0755

This is mode u=rwx g=rx o=rx

thanks robkg but it did'nt work for me :( can anyone give me a light?
everyone can delete another ones files.
