    • SSO_API_AUTH_SETTING: set API key, SEC key and remote SSO provider URL. This setting is used by underneath dj-api-auth module to proejct API accessing.

      SSO_API_AUTH_SETTING = {
          "apikey": "f4a05287",
          "seckey": "6a4eeaea54d54f51af703e79c6096d51",
          "url": "https://dj-sso-sample.herokuapp.com",
      }
      
    • SSO_REMOTE_URL_PREFIX (optional): SSO path in remote SSO provider. default /sso/

    • SSO_USER_STORAGE``(optional):  SSOUser storage solution, there are 2 storage backends in ``dj-sso-client already. default: SSOUserDBStorage

      • djssoclient.userstorage.SSOUserDBStorage: store user data in database
      • djssoclient.userstorage.SSOUserCacheStorage: store user data in cache. You will get better performance.
    • SSO_SETTING_CACHE (optional): if you selected SSOUserCacheStorage as your user storage backend, and you have more than one cache in settings.py, you can pick up the cache name here. default: default

Attention: SSOUserCacheStorage

The default django.core.cache.backends.locmem.LocMemCache stores data per process. In multi-process production environment (gunicorn on multi-core server), it may cause problem while using SSOUserCacheStorage as your user storage engine.

Please use dedicate cache system (Memcached or Redis) as cache backend to avoid this problem.

SSOUser

SSOUser is the user model to store user data. It can be used as database model class if you selected SSOUserDBStorage to be your user storage engine.

class SSOUser(AbstractBaseUser):
    username = models.CharField(unique=True, max_length=50)
    extras = models.TextField(default="{}")
    ...

extra user attributes : attributes not exists in the SSOUser class. (attributes except username, password, last_login etc.)

All extra user attributes can be access by getattr method or . operator. And they are stored in class member extras in JSON format.

Get your hands dirty

We already have a SSO provider (dj-sso-server) application running on Heroku: http://dj-sso-sample.herokuapp.com/ . Run the example application in folder example/ssoclient/ locally.

The API key using in the example application is binding with localhost:8000, so make sure you’re accessing local application by localhost:8000 rather than the 127.0.0.1:8000.

fresh login

  1. make sure you’re not logged in on http://dj-sso-sample.herokuapp.com/, you should see please log in with ...
  2. click sso login on local application, you will be redirected to http://dj-sso-sample.herokuapp.com/sso/….
  3. you will see user information after be redirected to local application.
  4. on http://dj-sso-sample.herokuapp.com/ , your status is still not logged-in

login with existing logged account

  1. log in with user name user1 and password 123 on http://dj-sso-sample.herokuapp.com/
  2. click sso login on local application, you will be redirected to http://dj-sso-sample.herokuapp.com/sso/…., but you will see a different login page with fresh login.
  3. select continue with current user? user1
  4. you will be logged in as user1 at local application

switch account

  1. if you select switch account and login with user2/456 from step 3 in previous sample
  2. you will be logged in as user2 at local application
