19412	Document that custom user models require a `user_permissions` M2M	Craig de Stigter	nobody	"It appears that `django.contrib.auth.backends.ModelBackend` requires that user models have a `user_permissions` `ManyToManyField`.

cf https://groups.google.com/d/msg/django-developers/K2cA2C3VeQw/6YoF1J9Sjx0J

This requirement isn't documented AFAICT. It should probably be mentioned in the [https://docs.djangoproject.com/en/dev/topics/auth/#auth-custom-user Custom User Models] docs where the other User requirements are listed.
