[gentoo-user] Finely tuning access permissions (in Samba)

[Mick]

Hi All,

I am trying to setup access permissions for a Samba file server and have so 
far done this much;

chmod -R ug+rwxs,o-r+x /data

The three MS Windows users on the server (george, viki & cad) can all create 
files and delete their own, but cannot delete a file that they have not 
created themselves.  I want to make (only) george able to delete files that 
he has not created himself.  How can I achieve that, without using ACLs - I 
will be setting up some tar, or rsync based back-up policy which I think does 
not retain POSIX ACLs.
