Authenticate against PAM
Provides an authenticate function that will allow the caller to authenticate
a user against the Pluggable Authentication Modules (PAM) on the system.
Implemented using ctypes, so no compilation is necessary.
There is one extra configuration option for pam. The `pam_service` that is
authenticated against. This defaults to `login`
.. code-block:: yaml
auth.pam.service: login
.. note:: Solaris-like (SmartOS, OmniOS, ...) systems may need ``auth.pam.service`` set to ``other``.
.. note:: PAM authentication will not work for the ``root`` user.
The Python interface to PAM does not support authenticating as ``root``.
.. note:: Using PAM groups with SSSD groups on python2.
To use sssd with the PAM eauth module and groups the `pysss` module is
needed. On RedHat/CentOS this is `python-sss`.
This should not be needed with python >= 3.3, because the `os` modules has the
`getgrouplist` function.
