ckanext-keycloak - Keycloak authentication extension

ckanext-keycloak is an extension for enabling user authentication with Keycloak, an open source software product to allow single sign-on (SSO) with Identity Management and Access Management aimed at modern applications and services.

This extension provides the ability for users to use access-tokens from Keycloak server to access CKAN functions via CKAN REST API.

Notes:

  • A new user will be created automatically in ckan database for the corresponding keycloak user if it does not exist.
  • Original ckan authentication still works normally with this extension.

Requirements

This extension was developed and tested under CKAN-2.7.3 and Keycloak-2.5.5

Installation

To install ckanext-keycloak:

  1. Activate your CKAN virtual environment, for example:

    . /usr/lib/ckan/default/bin/activate
    
  2. Install the ckanext-keycloak Python package into your virtual environment:

    pip install ckanext-keycloak
    
  3. Add keycloak setting in your CKAN config file (by default the config file is located at /etc/ckan/default/production.ini) as follows:

    ckan.plugins = keycloak <other-plugins>
    ckan.keycloak.authorization_endpoint = http://localhost/auth
    ckan.keycloak.realm = master
    ckan.keycloak.client_id = client_id
    ckan.keycloak.client_secret = client_secret
    ckan.keycloak.sysadmin_group_name = admin
    ckan.keycloak.profile_group_field = group
    ckan.keycloak.profile_username_field = preferred_username
    ckan.keycloak.profile_email_field = email
    ckan.keycloak.profile_fullname_field = name
    
  4. Restart CKAN. For example if you've deployed CKAN with Apache on Ubuntu:

    sudo service apache2 reload
