I am trying to use MongoEngine in a django project I am writing. I am having difficulty getting (or understanding how) the authentication backend works.

The user obj

Not sure if you are seeing any issues because you make no mention of any but I use mongoengine for my auth backend and this is how I would handle it:

from django.contrib.auth import login, User
from mongoengine.queryset import DoesNotExist

def login_view(request):
    try:
        user = User.objects.get(username=request.POST['username'])
        if user.check_password(request.POST['password']):
            user.backend = 'mongoengine.django.auth.MongoEngineBackend'
            login(request, user)
            request.session.set_expiry(60 * 60 * 1) # 1 hour timeout
            return HttpResponse(user)
        else:
            return HttpResponse('login failed')
    except DoesNotExist:
        return HttpResponse('user does not exist')
    except Exception
        return HttpResponse('unknown error')

You say the user is not stored in the request...if you mean it is not available in templates, you need to add the auth template context processor in your settings (in addition to the AUTHENTICATION_BACKENDS setting you have set already):

TEMPLATE_CONTEXT_PROCESSORS = (
    ...
    'django.contrib.auth.context_processors.auth',
    ...
)

To make the user attached to subsequent requests after login, set the AuthenticationMiddleware and the user will be an attribute of the request in all your views:

MIDDLEWARE_CLASSES = (
...
    'django.contrib.auth.middleware.AuthenticationMiddleware',
...
)
