pas.plugins.authomatic 1.2.0

Provides OAuth2/OpenID login for Plone using Authomatic.

OAuth2 / OpenId Authentication in Plone

Features

pas.plugins.authomatic provides OAuth2 and OpenID login capability for Plone sites by integrating the awesome Authomatic package.

Authomatic is a framework agnostic library
for Python web applications
with a minimalistic but powerful interface
which simplifies authentication of users
by third party providers like Facebook or Twitter
through standards like OAuth and OpenID.

Documentation

This package supports Plone sites using Volto or the Classic UI.

For the Classic UI:

• This package creates a view called authomatic-handler where you can login with different providers.
• The view can be used as well to add an identity from a provider to an existing account.
• The provider is choosen in the URL so if you call /authomatic-handler/PROVIDER you will use PROVIDER to login.

For Volto:

• Endpoint @login with GET: Returns list of authentication options
• Endpoint @login-authomatic with GET: Provide information to start the OAuth process.
• Endpoint @login-authomatic with POST: Handles OAuth login and returns a JSON web token (JWT).
• For Volto sites you must also install @plone-collective/volto-authomatic.

Configuration is, currently, done via Classic UI:

• Plugin configuration is available in the Controlpanel @@authomatic-controlpanel (linked under users)
• Example JSON configuration (first level key is the PROVIDER):

{
  "github": {
    "display": {
      "title": "Github",
      "cssclasses": {
          "button": "plone-btn plone-btn-default",
          "icon": "glypicon glyphicon-github"
      },
      "as_form": false
    },
    "propertymap": {
      "email": "email",
      "link": "home_page",
      "location": "location",
      "name": "fullname"
    },
    "class_": "authomatic.providers.oauth2.GitHub",
    "consumer_key": "5c4901d141e736f114a7",
    "consumer_secret": "d4692ca3c0ab6cc1f8b28d3ccb1ea15b61e7ef5c",
    "access_headers": {
      "User-Agent": "Plone Authomatic Plugin"
    }
  },
}

Installation

Add pas.plugins.authomatic to the Plone installation using pip:

pip install pas.plugins.authomatic

or add it as a dependency on your package's setup.py

    install_requires = [
        "pas.plugins.authomatic",
        "Products.CMFPlone",
        "plone.restapi",
        "setuptools",
    ],

Start Plone and activate the plugin in the addons control-panel.

Configuration

Using Classic UI, go to the Authomatic controlpanel.

Configuration parameters for the different authorization are provided as JSON text in there. We use JSON because of its flexibility.

Details about the configuration of each provider can be found at Authomatic provider section.

There are some differences in configuration:

• Value of "class_" has to be a string, which is then resolved as a dotted path.

• Each provider can get an optional entry display with sub-enties such as:

  • title which is used in the templates instead of the section name.
  • iconclasses which is applied in the templates to an span.
  • buttonclasses which is applied in the templates to the button.
  • as_form (true/false) which renders a form for OpenId providers.

• Each provider can get an optional entry propertymap. It is a mapping from authomatic/provider user properties to plone user properties, like "fullname": "name",. Look at each providers documentation which properties are available.
