Open ID
Testando o python-openid.. Acho que a partir do exemplo de servidor (https://github.com/openid/python-openid/blob/master/examples/server.py) è possivel ler num arquivo mudando a doLogin:
def doLogin(self):
if 'submit' in self.query:
if 'user' in self.query:
self.user = self.query['user']
# Codigo para ler o arquivo e montar um objeto user on-the-fly a
# partir dos dados no arquivo
else:
self.user = None
self.redirect(self.query['success_to'])
elif 'cancel' in self.query:
self.redirect(self.query['fail_to'])
else:
assert 0, 'strange login %r' % (self.query,)
Django Authentication Backend
Esse caminho è mais direto e possivelmente o melhor para poder atender demandas especificas. Precisa criar uma classe que implemente duas funções: get_user(user_id) and authenticate(**credentials).
- get_user
- recebe user_id que pode ser o nome do usuario o algum codigo o importante que seja a primary key do objeto User
- retorna um objeto User
- authenticate(**credentials)
- recebe alguns argumentos por exemplo:
class MyBackend(object):
def authenticate(self, username=None, password=None):
# Check the username/password and return a User. ...

from django.conf import settings
from django.contrib.auth.models import User, check_password
