[autoform] Go through guess_field even when field class is specified using uicfg
guess_field does not only find the proper field class for some
attribute/relation, but also do some basic configuration depending on e.g.
constraints. Before this patch, if one was specifying explicitly the field class
using uicfg.autoform_field, this automatic configuration wasn't happening.
Change form.field_by_name and ff.guess_field so explicit class are also
automatically configured now.
Closes #14474840
Authentication
==============
Overview
--------
A default authentication stack is provided by the :mod:`cubicweb.pyramid.auth`
module, which is included by :mod:`cubicweb.pyramid.default`.
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)
