I don't know what exactly did you do wrong but here is my code and it worked 
so far for me:


def onObjectAdded(event):
    """ Initializes the centershock object: adds und configures some utilities 
when being added. """
    
    if ICentershock.providedBy(event.object):
        if not ISite.providedBy(event.object):
            # Make it a site
            cs = event.object
            site_manager = LocalSiteManager(cs)
            cs.setSiteManager(site_manager)
            
                     
            # Add PAU
            pau = ensureUtility(cs, 
zope.app.security.interfaces.IAuthentication, '', 
zope.app.authentication.authentication.PluggableAuthentication , asObject = 
True)
            pau.credentialsPlugins = (u'Session Credentials',)
            
            principal_folder = 
zope.app.authentication.principalfolder.PrincipalFolder(prefix = "cs")
            pau["centershock users"] = principal_folder
            registration = UtilityRegistration("centershock users", 
zope.app.authentication.interfaces.IAuthenticatorPlugin, principal_folder)
            registration_manager = pau.registrationManager
            registration_manager.addRegistration(registration)
            registration.status = u'Active'
            pau.authenticatorPlugins = (u"centershock users",)

Hope that helps you,
