Is there a way to use django's built-in user authentication in Google app engine (Python)?

I understand that Google App Engine has it's own user authentication facilities but it offers only three possible way to authenticate:

• A Google Account
• An account on your Google Apps domain
• An OpenID identifier

But what I want is to have the same power that Django's django.contrib.auth gives, with permissions and groups with internal user database. Is there a way开发者_运维技巧 to have this Django module ported and used in Google app engine?

You can use non-rel to run Django on App Engine.
