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. ...
