        from the openid provider, where keys in `ask_for` are marked as
        required, and keys in `ask_for_optional` are marked as optional.

        The following strings can be used in the `ask_for` and
        `ask_for_optional` parameters:
        ``aim``, ``blog``, ``country``, ``dob`` (date of birth), ``email``,

        ``timezone``, ``website``, ``yahoo``

        `extensions` can be a list of instances of OpenID extension requests
        that should be passed on with the request. If you use this, please make
        sure to pass the Response classes of these extensions when initializing
        OpenID.

        `immediate` can be used to indicate this request should be a so-called
        checkid_immediate request, resulting in the provider not showing any
        UI.
        Note that this adds a new possible response: SetupNeeded, which is the
        server saying it doesn't have enough information yet to authorized or
        reject the authentication (probably, the user needs to sign in or
        approve the trust root).
