I think it's fine the way it is beside one thing.


# This is fine, it's added just like all the other utilites.

pau = ensureUtility(cs, IPluggableAuthentication, '', 
PluggableAuthentication , asObject = True)



# This is ok for adding, but I got no idea how to register it. A nice thing 
would be function like ensurePlugin that works analog to ensureUtility (adds 
und registers a plugin, does the NameChooser call if needed, ...)

principal_folder = PrincipalFolder(prefix = "cs")
pau["PrincipalFolder"] = principal_folder
            

# This is pretty straightforward but I was not expecting to give a string, 
rather I thougt it expected a Interface or something like that.

pau.credentialsPlugins = (u'Session Credentials',)



The only thing I would change is to add a ensurePlugin function to either the 
pau object itself or also as part of zope.app.appsetup. (like all the other 
ensure* functions).
