register_models is registering models from apps that are not installed

[yashh]

I am not using django's built in auth models. Instead I wrote a auth app with a user model of my choice. I wrote my own Authentication middleware and it works fine. However when I run django test suite, django is registering models Permission, Message, Group from django.contrib.auth even though "django.contrib.auth" is not mentioned in INSTALLED_APPS. Here is a indetail trace of the test suite

The traceback ends when Permission model is passed to register_models

There isn't anywhere near enough detail here to work out if what you're describing is a Django problem, or a problem with your own codebase.

A valid test report gives the triager enough data to reproduce your problem on their own. This report has a stack trace, and a vague description that says you've written your own authentication backend.

Please reopen if you can provide enough detail to reproduce the problem. This means a detailed set of instructions, or a sample project (a *minimal* sample project) that exhibits the problem. Don't just dump your entire codebase on our lap -- do some pruning and cut out anything that isn't *directly* related to the problem at hand.
