Multiple Authentication Backends
Multiple authentication backends are now possible on the multi-auth branch.
To get a copy, execute the following:
svn co http://code.djangoproject.com/svn/django/branches/multi-auth
The documentation has been updated and can be found here: http://code.djangoproject.com/browser/django/branches/multi-auth/docs/authentication.txt
If you have problems, or the docs are unclear, please post your questions to the django-users or django-developers list.
Note: For those paying attention to this proposal, credential plugins have been completely removed. While useful for some applications, the added complexity just wasn't worth it.
Start: Added by a relative newbie on May 12, 2006
Note: In the multi-auth branch (2892), you need to set AUTHENTICATION_BACKENDS to a tuple, similar to MULTIAUTH_BACKENDS above. the authenticate method looks for this setting in your settings.py file. I have it working and all I have is:
AUTHENTICATION_BACKENDS = ( "django.contrib.auth.copy_of_backends.LDAPBackend", )
I made a copy of contrib.auth.backends so the svn can update it without overwriting my LDAPBackend class. Don't know if that is the best way to do it or not, but it works.
I recommend you put it someplace like myapp.auth.LDAPBackend. Maintianing patches to Django is going to be a PITA. --Joseph Kocherhans
I also hacked the contrib.auth.models file to change the check_password function to check against our LDAP server, and added a few small functions to check the type of user account. I know this will break next time I update the source, but I have a copy of that as well. There is surely a better way, but I'm still learning.
You shouldn't have to hack the check_password function at all. It isn't called directly by Django's views anymore... only indirectly via django.contrib.auth.backends.ModelBacked, which you aren't using. -Joseph Kocherhans

sample LDAPBackend class
From the same newbie as above on May 12, 2006
This is located in the contrib/auth/copy_of_backends.py file. The two original models are still in the file as well. I just added this one in the middle.
class LDAPBackend: """ Authenticate against our LDAP Database """ def authenticate(self, username=None, password=None): # bind and see if the user exists if ldap.userExists(username): # user exists in our LDAP, see if they exist in Django # if not, add them to django's user database since django relies on that try: user = User.objects.get(username=username) if ldap.check_ldap_password(username, password): return user except User.DoesNotExist: # get the first name, last name, email from ldap u = ldap.getUser(username) # get user attributes here as well, like mail, fname, lname user = User(username=username, password='getmefromldap') user.email = mail user.first_name = fname user.last_name = lname user.is_staff = False user.is_superuser = False user.save() return user else: return None def get_user(self, user_id): try: return User.objects.get(pk=user_id) except User.DoesNotExist: return None
And it worked! I was able to logon as a user who had no entry in Django, and then it added my entry and away I went. Pretty nice stuff.
