django-tequila

Tequila authentication for django.

Requirements

django-tequila needs the Django 2.2 LTS

This project also expects a fully operational Tequila server.

Installation

pip install django-tequila

Configuration

settings.py

• Add at the end of your MIDDLEWARE_CLASSES:

  'django_tequila.middleware.TequilaMiddleware',
  

• Add to INSTALLED_APPS:

  'django_tequila',
  

• Add the line:

  AUTHENTICATION_BACKENDS = ('django_tequila.django_backend.TequilaBackend',)
  

• Set a name that will be displayed on the tequila login page:

  TEQUILA_SERVICE_NAME = "django_tequila_service"
  

• Finally, add / customize login/logout workflow

  LOGIN_URL = "/login"
  LOGIN_REDIRECT_URL = "/"
  LOGOUT_URL = '/'
  LOGIN_REDIRECT_IF_NOT_ALLOWED = "/not_allowed"
  LOGIN_REDIRECT_TEXT_IF_NOT_ALLOWED  = "Not allowed"
  

urls.py

• Add these lines:

  from django_tequila.urls import urlpatterns as django_tequila_urlpatterns
  
  urlpatterns += django_tequila_urlpatterns
  

Login/logout links

If you want the user to be redirected to a specific page after he logged/logout successfully, you have to add the 'next' parameter to your login url, like the default Django authentication backend. See Django help for login-redirect-url for more information.

Profile customization

You may want to keep some additional information about the user. Take a look at this page for more information about profile customization.

Here is an example for a profile for Django 2.0

• Create a custom User model in your models.py (see ./sample_app/python3-8-django-2/django_tequila_app/models.py)

• in your settings.py, tell django to use your model (see ./sample_app/python3-8-django-2/django_tequila_app/settings.py)::

  AUTH_USER_MODEL = 'my_app.User' TEQUILA_CUSTOM_USERNAME_ATTRIBUTE = "uniqueid"

• Update your database:

  ./manage.py syncdb
  

Site Admin customizations

• Add or modify your admin.py file, like ./sample_app/python3-8-django-2/django_tequila_app/admin.py

Additional tips and settings

Advanced settings

• If you need to use your personal server, change this parameter:

  TEQUILA_SERVER_URL = "https://tequila.epfl.ch"
  

• You may want to create an inactive user when someone try to connect to your app. So you can manually control who access it. If this is the case, add this line to settings.py:

  TEQUILA_NEW_USER_INACTIVE = True
  

• You may want to add some custom allow with Tequila. If this is the case, add this line to settings.py:

  TEQUILA_CONFIG_ALLOW = 'categorie=shibboleth'
  

  or, for multiple allow :

  TEQUILA_CONFIG_ALLOW = 'categorie=shibboleth|categorie=epfl-old'

• You may want to add some custom paramaters with Tequila. If this is the case, add this line to settings.py:

  TEQUILA_CONFIG_ADDITIONAL = {'allowedorgs': 'EPFL, UNIL'}
  

• Everytime the user connect trought the Tequila process, he is redirected to an url that has a 'key' parameter. For some esthetic reasons,you may want to remove this parameter, so add this line to settings.py:

  TEQUILA_CLEAN_URL = True
  

  As it creates a redirect to the cleaned address and add an additional page hit, The value by default is False

• You can force a strong authentication so add this line to settings.py:

  TEQUILA_STRONG_AUTHENTICATION = True
  

  Default value is False

• The only value that is truly unique is the sciper ('uniqueid' in Tequila). If your application need a different usage, you can set to a different field (at your own risk though). You can add this line to settings.py:

  TEQUILA_CUSTOM_USERNAME_ATTRIBUTE = 'uniqueid'
  

  Ex. : username, email, etc.

  Default value is username

• You may want to allow multiple hosts to fetch requested information. If this is the case, add this line to settings.py:

  TEQUILA_ALLOWED_REQUEST_HOSTS = "the host ip"
  

  Ex. : "192.168.1.1|192.168.1.2"

  Default to None

• You can allow guests to log in so add this line to settings.py:

  TEQUILA_ALLOW_GUESTS = True
  

  Default value is False

Sample app

You can find some django app examples in ./django-tequila/sample_app/python3-8-django-2 Add a .env file like the ./.env.sample and the run it with Django 2, at the root of the project

make build init-db

Or, for Django 1.11, prefix every make with the DOCKERFILES env set, like this

DOCKERFILES='-f sample_app/python3-6-django-1/docker-compose.yml' make build init-db

Then open https://127.0.0.1/ in your browser

Use make stop to shut it down

Logging

Sometimes we struggle to get the aimed result, showing some log may help :

• Add and customize as you need this logger to your settings

  'django_tequila': {
          'handlers': ['console'],
          'level': 'DEBUG',
      },
  

Debugging

• The sample app can be used to debug. We use remote_pdb for this case. Set this snippet in the code

  from remote_pdb import RemotePdb
  RemotePdb('127.0.0.1', 4445).set_trace()
  

• Then go into the container

  make bash
  

• Finally connect to the debug session with

  telnet 127.0.0.1 4445
