Re: authenticate=None mistery: can't authenticate from the web but it works from the command line
In addition to the 'user'/'username' typo, this login view would not
log a user in. In order to log a user in, you must verify their
credentials by calling django.contrib.auth.authenticate(), which will
either return an authenticated user or None.
Once the credentials are verified, you must then call
django.contrib.auth.login() to persist login information in the users
session. Without calling login(), the user will only be authenticated
on the single request in which they authenticated.
More documentation on how to use authenticate and login is here:
https://docs.djangoproject.com/en/1.4/topics/auth/#django.contrib.auth.login
