backends.py

from django.contrib.auth.backends import ModelBackend
from django.contrib.auth.models import User  

class EmailBackend(ModelBackend):
    
    def authenticate(self, **credentials):
        if 'username' in credentials:
            return super(EmailBackend, self).authenticate(**credentials)
        
        try:
            user = User.objects.get(email=credentials.get('email'))
            if user.check_password(credentials.get('password')):
                return user
        except User.DoesNotExist:
            return None

on the settings.py , i created:

AUTHENTICATION_BACKENDS = (
'myAutenticate',
'django.contrib.auth.backends.ModelBackend',
)

then, i created an app named myAutenticate. After, i created the backends.py inside the folder myAutenticate and placed the that you suggested on this gist topic.

now, i'm getting the following error message: "Error importing authentication backend myAutenticat: "No module named myAutenticat"

do i miss something?

Yes, you missed the complete path of your backend. You should use the following pattern: projectname.applicationname.backends.EmailBackend. Remember that Google is your friend ;-)

thanks dude,

Now i'm getting this(I swear I have researched this one enough on the internet before ask you ;) ):

Exception Value:
Module "goow.myAutenticate" does not define a "EmailBackend" authentication backend

Maybe you'll need:
Django Version: 1.2.5
Exception Type: ImproperlyConfigured
Exception Location: /usr/local/lib/python2.6/dist-packages/django/contrib/auth/init.py in load_backend, line 22
Python Executable: /usr/bin/python2.6
Python Version: 2.6.6

I really appreciate.
