Middleware for using Shibboleth with Django. Requires Django 1.7 or above.

• Install directly from Github with pip:

  pip install [email protected]:KonstantinSchubert/django-shibboleth-adapter.git
  
  

• In settings.py :

• Enable the RemoteUserBackend.

  AUTHENTICATION_BACKENDS += (
    'shibboleth.backends.ShibbolethRemoteUserBackend',
  )

• Add the Django Shibboleth middleware. You must add the django.contrib.auth.middleware.ShibbolethRemoteUserMiddleware to the MIDDLEWARE_CLASSES setting after the django.contrib.auth.middleware.AuthenticationMiddleware. For example:

  MIDDLEWARE_CLASSES = (
  ...
  'django.contrib.auth.middleware.AuthenticationMiddleware',
  'shibboleth.middleware.ShibbolethRemoteUserMiddleware',
  ...
  )

• Define the shibboleth user key. This is the shibboleth attribute that is used to identify the user. It becomes the user name in django.

  SHIBBOLETH_USER_KEY='<shibboleth-attribute>'

• Map Shibboleth attributes to Django User model attributes via SHIBBOLETH_ATTRIBUTE_LIST. The exsting attributes can be found in the django documentation. You might want to extend them via inheritance.

SHIBBOLETH_ATTRIBUTE_LIST= [ { "shibboleth_key": "", "user_attribute" : "", "required" : }, { "shibboleth_key": "shib_user_email", "user_attribute" : "email", "required" : True }, ... ]

  Note: The Django user object has not many attributes. Note that all shibboleth attributes will be accessible in django via  the `META` dictionary in the `request` object. 

* Login and Logout url - set this to the login/Logout handler of your shibboleth installation. 
  In most cases, this will be something like:

  ```python
  SHIBBOLETH_LOGIN_URL = 'https://your_domain.edu/Shibboleth.sso/Login'
  SHIBBOLETH_LOGOUT_URL = 'https://your_domain.edu/Shibboleth.sso/Logout'

• Set the django LOGIN_URL to the login-view provided by this package:

  LOGIN_URL = '/shib/login/'

  You can also manually set this this url in your templates. It is necessary to specify a redirect location using the url parameter next.

• You can try to set the SHIBBOLETH_LOGOUT_REDIRECT_URL which defines where the user will be redirected after logout. You identity provider might ignore this setting.

• Apache configuration - make sure the shibboleth attributes are available to the app. The shibboleth variables are passed into the HttpRequest.META dictionary via wsgi.

  <Location /app>
    AuthType shibboleth
    Require shibboleth
  </Location>
  

If you would like to verify that everything is configured correctly, follow the next two steps below. It will create a route in your application at /yourapp/shib/ that echos the attributes obtained from Shibboleth. If you see the attributes you mapped above on the screen, all is good.

• Add shibboleth to installed apps.

  INSTALLED_APPS += (
    'shibboleth',
  )

• Add below to urls.py to enable the included sample view. This view just echos back the parsed user attributes, which can be helpful for testing.

  urlpatterns += patterns('',
    url(r'^shib/', include('shibboleth.urls', namespace='shibboleth')),
  )

##Optional ###Template tags

• Template tags are included which will allow you to place {{ login_link }} or {{ logout_link }} in your templates for routing users to the login or logout page. These are available as a convenience and not required. To activate add the following to settings.py.

   TEMPLATE_CONTEXT_PROCESSORS += (
      'shibboleth.context_processors.login_link',
      'shibboleth.context_processors.logout_link'
   )
