Authenticating against Django's user database from Apache
|
|
=========================================================
|
|
|
|
Since keeping multiple authentication databases in sync is a common problem when
|
|
dealing with Apache, you can configure Apache to authenticate against Django's
|
|
:doc:`authentication system </topics/auth/index>` directly. This requires Apache
|
|
version >= 2.2 and mod_wsgi >= 2.0. For example, you could:
|
|
|
|
* Serve static/media files directly from Apache only to authenticated users.
|
|
|
|
* Authenticate access to a Subversion_ repository against Django users with
|
|
a certain permission.
|
|
|
|
* Allow certain users to connect to a WebDAV share created with mod_dav_.
|
|
|
|
.. note::
|
|
If you have installed a :ref:`custom User model <auth-custom-user>` and
|
|
want to use this default auth handler, it must support an `is_active`
|
|
attribute. If you want to use group based authorization, your custom user
|
|
must have a relation named 'groups', referring to a related object that has
|
|
a 'name' field. You can also specify your own custom mod_wsgi
|
|
auth handler if your custom cannot conform to these requirements.

Authentication with mod_wsgi
|
|
============================
|
|
|
|
Make sure that mod_wsgi is installed and activated and that you have
|
|
followed the steps to setup
|
|
:doc:`Apache with mod_wsgi </howto/deployment/wsgi/modwsgi>`
|
|
|
|
Next, edit your Apache configuration to add a location that you want
|
|
only authenticated users to be able to view:
|
|
|
|
.. code-block:: apache
|
|
|
|
WSGIScriptAlias / /path/to/mysite.com/mysite/wsgi.py
|
|
|
|
WSGIProcessGroup %{GLOBAL}
|
|
WSGIApplicationGroup django
|
|
|
|
<Location "/secret">
|
|
AuthType Basic
|
|
AuthName "Top Secret"
|
|
Require valid-user
|
|
AuthBasicProvider wsgi
|
|
WSGIAuthUserScript /path/to/mysite.com/mysite/wsgi.py
|
|
</Location>
|
|
|
|
The ``WSGIAuthUserScript`` directive tells mod_wsgi to execute the
|
|
``check_password`` function in specified wsgi script, passing the user name and
|
|
password that it receives from the prompt. In this example, the
|
|
``WSGIAuthUserScript`` is the same as the ``WSGIScriptAlias`` that defines your
|
|
application :doc:`that is created by django-admin.py startproject
|
|
</howto/deployment/wsgi/index>`.
|
|
|
|
.. admonition:: Using Apache 2.2 with authentication
|
|
|
|
Make sure that ``mod_auth_basic`` and ``mod_authz_user`` are loaded.
|
|
|
|
These might be compiled statically into Apache, or you might need to use
|
|
LoadModule to load them dynamically in your ``httpd.conf``:
|
|
|
|
.. code-block:: apache
|
|
|
|
LoadModule auth_basic_module modules/mod_auth_basic.so
|
|
LoadModule authz_user_module modules/mod_authz_user.so
|
|
|
|
Finally, edit your WSGI script ``mysite.wsgi`` to tie Apache's authentication
|
|
to your site's authentication mechanisms by importing the ``check_password``
|
|
function:
|
|
|
|
.. code-block:: python
|
|
|
|
import os
|
|
import sys
|
|
|
|
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
|
|
|
|
from django.contrib.auth.handlers.modwsgi import check_password
|
|
|
|
from django.core.handlers.wsgi import WSGIHandler
|
|
application = WSGIHandler()
|
|
|
|
|
|
Requests beginning with ``/secret/`` will now require a user to authenticate.
|
|
|
|
The mod_wsgi `access control mechanisms documentation`_ provides additional
|
|
details and information about alternative methods of authentication.
|
|
|
|
.. _access control mechanisms documentation: http://code.google.com/p/modwsgi/wiki/AccessControlMechanisms
|
|
|
|
Authorization with mod_wsgi and Django groups
|
|
---------------------------------------------
|
|
|
|
mod_wsgi also provides functionality to restrict a particular location to
|
|
members of a group.
|
|
|
|
In this case, the Apache configuration should look like this:
|
|
|
|
.. code-block:: apache
|
|
|
|
WSGIScriptAlias / /path/to/mysite.com/mysite/wsgi.py
|
|
|
|
WSGIProcessGroup %{GLOBAL}
|
|
WSGIApplicationGroup django
|
|
|
|
<Location "/secret">
|
|
AuthType Basic
|
|
AuthName "Top Secret"
|
|
AuthBasicProvider wsgi
|
|
WSGIAuthUserScript /path/to/mysite.com/mysite/wsgi.py
|
|
WSGIAuthGroupScript /path/to/mysite.com/mysite/wsgi.py
|
|
Require group secret-agents
|
|
Require valid-user
|
|
</Location>
|
|
|
|
To support the ``WSGIAuthGroupScript`` directive, the same WSGI script
|
|
``mysite.wsgi`` must also import the ``groups_for_user`` function which
|
|
returns a list groups the given user belongs to.
|
|
|
|
.. code-block:: python
|
|
|
|
from django.contrib.auth.handlers.modwsgi import check_password, groups_for_user
|
|
|
|
Requests for ``/secret/`` will now also require user to be a member of the
|
|
"secret-agents" group.
