Hi Florian,
the simplest thing to do (or what i ended up doing) was creating a
credentialsPlugin that provided similar functionality to the standard
session credentials plugin, but where the standard session credentials
plugin's extractCredentials method expects to pull 'login' and
'password' out of request.get(), you just pull
request.get('form.login') or something similar.  just return the
credentials dict back out to the principal folder (or whatever
authenticator you're using) authenticateCredentials method with a dict
of the form {'login': credentials.getLogin(), 'password':
credentials.getPassword() } where credentials is a SessionCredentials
object created from your request.get('form.login') and
request.get('form.password').

look at zope.app.authentication.session's design pattern for more.
