By enabling this backend: AUTHENTICATION_BACKENDS = ( 'path.to.my.backends.CaseInsensitiveModelBackend', ) Your users will now be able to log in with their username, no matter whether the letters are upper- or lower-case.
I wanted lookups on tags to be case insensitive by default, so that things like Tag.objects.get(name='Tag') would return any similar tags (ignoring case differences), i.e. `<Tag: tag>`. This snippet makes lookup on the 'name' field case-insensitive by default, although case-sensitive lookups can still be achieved with 'name__exact'. Methods like get_or_create will work as expected and be case-insensitive.
