Django Admin - Re-authentication?

I'm in a bit of a dilemma at the moment regarding Django's admin backend. The default authentication system allows already logged-in users that have staff privileges to access the admin site, however it just lets them straight in.

This doesn't feel “right” to me, and I'm wondering if it would be difficult to at least require a re-authentication of that same session in order to get into the backend.

Preferably though, it'd be good if the frontend sessions could be separated from the backend ones (though still using the same user objects), this would allow a clean separation of both parts of the site. Would this perhaps require two separate aut开发者_Go百科hentication backends? Would something like this be difficult to achieve?

Here's an idea: run the admin app on a different domain to the frontend. The cookies won't be valid in the other domain, so the user will have to log in again. All you'd need would be a separate Apache vhost and a basic settings.py that just has contrib.admin in INSTALLED_APPS.

You could probably implement a middleware that asks for authentication when accessing the admin site from a referer not in the admin site. It could log the person out and make them log back in, but even that wouldn't be necessary. Just require another password entry, and redirect them if it fails. It might involve setting a session variable, is_admin_authenticated or something.
