Django contrib.auth without permissions
It depends what you mean, really. Although the permissions are part of the auth app, there's no requirement to actually assign any, or check them at any point: that's entirely up to you. Most of the projects I have done use auth in exactly this way, to check logins and nothing else.
Is it possible to use the built-in django.contrib.auth mechanism without enabling permissions at all?
I just need a simple registration and login system.  
Thanks.
