Hi, I'm struggling a bit to get rid of the friendly form identifier and
challenger, and do my own Authenticator in a turbogears 2.1 project.
I've got a 'faceless' web services server that won't even have a
login form, since no human will ever visit the site. So I want
to retain the session cookie mechanism, and the sa_auth
module that uses the default Group, User, and Permission
model in SQL Alchemy. I just am going to do my own
Authentication, and get rid of the Challenger.
So far I've implemented an IAuthenticator
class ShaAuthenticator(IAuthenticator):
#implements(IAuthenticator)
def authenticate(self, environment, identity):
if not 'user_email' in identity:
return None
...
and in app_cfg.py
hash_auth = ShaAuthenticator
base_config.sa_auth.authenticators = [('hash_auth', hash_auth)]
# got rid of the challenger
base_config.sa_auth.form_plugin = None
#and am keeping
base_config.auth_backend = 'sqlalchemy'
base_config.sa_auth.dbsession = model.DBSession
If I try to run at the moment I see:
ValueError: hash_auth: An object has failed to implement
interface <InterfaceClass
repoze.who.interfaces.IAuthenticator>
The authenticate attribute was not provided.
I didn't find much help on the turbogears google group, I'm hoping
someone might be able to point me in the right direction here.
Thanks,
-Jim
