Authentication

==============

Overview

--------

The authentication stack is built around `pyramid_multiauth`_, and provides a

few default policies that reproduce the default cubicweb behavior.

.. note::

    Note that this module only provides an authentication policy, not the views

    that handle the login form. See :ref:`login_module`

Customize

---------

The default policies can be individually deactivated, as well as the default

authentication callback that returns the current user groups as :term:`principals`.

The following settings can be set to `False`:

-   :confval:`cubicweb.auth.update_login_time`. Activate the policy that update

    the user `login_time` when `remember` is called.

-   :confval:`cubicweb.auth.authtkt` and all its subvalues.

-   :confval:`cubicweb.auth.groups_principals`

Additionnal policies can be added by accessing the MultiAuthenticationPolicy

instance in the registry:

.. code-block:: python

    mypolicy = SomePolicy()

    authpolicy = config.registry['cubicweb.authpolicy']

    authpolicy._policies.append(mypolicy)
