The manpage for smb.conf says:

           This parameter is a synonym for username.

      username (S)
           Multiple users may be specified  in  a  comma-delimited
           list,  in  which  case  the  supplied  password will be
           tested against each username in turn (left to right).

This is very different from the "valid users" parameter.  I think the 
securing-samba.html file is wrong in saying they are equivalent.  If I'm 
reading it right, you want "valid users = %S".

Why not just fix the unix permissions?  We set home dirs to 700 and 
public_html to 755 here.
