[Samba] Problem with example: Chapter 15 of howto

[Oliver Schulze L.]

Hi,
In Chapter15 of the official Howto, in this section:
"Users Cannot Write to a Public Share"
http://us3.samba.org/samba/docs/man/Samba-HOWTO-Collection/AccessControls.html#id2595814

The point 5 is not working on RHEL4 (CentOS):
--------------------------------------
Now type:
$ su - jill
$ cd /foodbar
$ touch Afile
$ ls -al
You should see that the file Afile created by Jill will have ownership 
and permissions of Jack, as follows:
-rw-r--r--  1 jack  engr     0 2003-02-04 09:57 Afile
--------------------------------------

I only see this:
-rw-r--r--  1 jill  engr     0 2003-02-04 09:57 Afile

Is this a problem with RHEL4?

Thanks
Oliver
