You should not create the user via the normal User(...)
syntax, as others have suggested. You should always use User.objects.create_user()
, which takes care of setting the password properly.
user@host> manage.py shell
>>> from django.contrib.auth.models import User
>>> user=User.objects.create_user('foo', password='bar')
>>> user.is_superuser=True
>>> user.is_staff=True
>>> user.save()
