**This project is in ALFA version and is rapidly changing. DO NOT USE IT FOR PRODUCTION SITES.**

Important things that you should know:

- Although OpenID was built on top of OAuth2, this isn't an OAuth2 server. Maybe in a future it will be.
- This cover ``authorization_code`` flow and ``implicit`` flow, NO support for ``hybrid`` flow at this moment.
- Only support for requesting Claims using Scope Values.
- Despite that implementation MUST support TLS. You can make request without using SSL. There is no control on that.

Settings
********

Add required variables to your project settings.

.. code:: python

    # REQUIRED.

    # Your server provider url.
    SITE_URL = 'http://localhost:8000'

    # Used to log the user in.
    # See: https://docs.djangoproject.com/en/1.7/ref/settings/#login-url
    LOGIN_URL = '/accounts/login/'

    # OPTIONAL.

    DOP_CODE_EXPIRE = 60*10 # 10 min.
    DOP_IDTOKEN_EXPIRE = 60*10, # 10 min.
    DOP_TOKEN_EXPIRE = 60*60 # 1 hour.


********************
Create User & Client
********************

First of all, we need to create a user: ``python manage.py createsuperuser``.

Then let's create a Client. Start django shell: ``python manage.py shell``.

.. code:: python

    >>> from openid_provider.models import Client
    >>> c = Client(name='Some Client', client_id='123', client_secret='456', response_type='code', redirect_uris=['http://example.com/'])
    >>> c.save()

*******************
/authorize endpoint
*******************

Example of an OpenID Authentication Request using the ´´Authorization Code´´ flow.

.. code:: curl

    GET /openid/authorize?client_id=123&redirect_uri=http%3A%2F%2Fexample.com%2F&response_type=code&scope=openid%20profile%20email&state=abcdefgh HTTP/1.1
    Host: localhost:8000
    Cache-Control: no-cache
    Content-Type: application/x-www-form-urlencoded

****
Code
****

After the user accepts and authorizes the client application, the server redirects to:

.. code:: curl

    http://example.com/?code=5fb3b172913448acadce6b011af1e75e&state=abcdefgh

We extract the ``code`` param and use it to obtain access token.

***************
/token endpoint
***************

.. code:: curl

    POST /openid/token/ HTTP/1.1
    Host: localhost:8000
    Cache-Control: no-cache
    Content-Type: application/x-www-form-urlencoded

    client_id=123&client_secret=456&redirect_uri=http%253A%252F%252Fexample.com%252F&grant_type=authorization_code&code=[CODE]&state=abcdefgh

******************
/userinfo endpoint
******************

.. code:: curl

    POST /openid/userinfo/ HTTP/1.1
    Host: localhost:8000
    Authorization: Bearer [ACCESS_TOKEN]
