[Zope] Authorization by Hostname or Address

[Pierre Godefroy]

I have read and applied the Zope "How-To" concerning authorization by 
Hostname or Address at :

http://www.zope.org/Members/muesli/AuthByAddress

It works, but I would like to be able to open up access for a whole domain 
without having the user being requested to type in a login, even if there 
is no password control.

Is there a way to create a kind "anonymous" user in a "User Folder" who 
would only have a domain restriction and no "login" atached to it? It seems 
that any user has of course to be created with an id and hence this id is 
being requested as the login.
