License

MIT license, see LICENSE.txt for full text.

Setup

SSL

Set up nginx and create SSL certificates for your server and set up the paths to server private key, server certificate and CA certificate used to sign the client certificates. Example configuration file is in samples/nginx.conf

If you are on OS X, I suggest OS X KeyChain access for doing this for testing, as it will automatically make your client certificates available in all both Google chrome & Safari. Instructions can be found e.g. http://www.dummies.com/how-to/content/how-to-become-a-certificate-authority-using-lion-s.html

On other platforms, there are many tutorials on how to do this with OpenSSL e.g. http://pages.cs.wisc.edu/~zmiller/ca-howto/

Restart your ngninx (sudo nginx -s restart), make sure your green unicorn is running and check that your https:// url loads your application and the server certificate is valid.

This module

1. run setup.py (sudo python setup.py install) or install the latest release usning pip install django_ssl_auth
2. edit your settings.py
   1. add "django_ssl_auth.SSLClientAuthMiddleware" to your MIDDLEWARE_CLASSES
   2. add "django_ssl_auth.SSLClientAuthBackend" to your AUTHENTICATION_BACKENDS

Configuration

There are two things you need to do in settings.py

1. Define a function that can return a dictionary with fields that are required by your user model, e.g. USER_DATA_FN = 'django_ssl_auth.fineid.user_dict_from_dn is a sample implementation that takes the required fields from the DN of a Finnish government issued ID smart card for the contrib.auth.models.User.
2. To automatically create Users for all valid certificate holders, set AUTOCREATE_VALID_SSL_USERS = True

For details, see testapp/ssltest/settings.py
