OpenProject OmniAuth CAS Single-Sign On

This plugin provides the OmniAuth CAS strategy into OpenProject.

Add the following entries to your Gemfile.plugins in your OpenProject root directory:

gem "openproject-auth_cas", git: 'git@github.com:oliverguenther/openproject-auth_cas', branch: 'stable'

For OpenProject < 8.2.0, please manually add the Auth Plugins gem before adding openproject-auth_cas:

gem 'openproject-auth_plugins', git: 'git@github.com:finnlabs/openproject-auth_plugins', branch: 'stable'
gem "openproject-auth_cas", git: 'git@github.com:oliverguenther/openproject-auth_cas', branch: 'stable'

• omniauth-cas gem
• OpenProject
• openproject-auth_plugins (Included in OpenProject core since 8.2.0)

To add your own CAS strategy provider(s), create the following settings file (relative to your OpenProject root):

config/plugins/auth_cas/settings.yml

with the following contents:

your-provider-name:
  name: "your-provider-name"
  url: "https://sso.example.org"
  display_name: "My CAS provider"
  # Use the default CAS icon
  icon: "auth_provider-cas.png"
  # Extended Attributes mapping
  uid_key: "username"

The plugin simply passes all options to omniauth-cas. See their configuration documentation for further details.

If you have the use-case of multiple CAS / Single-Sign On providers, simply add several providers to your yaml config, OpenProject will handle the rest automatically.

To add a custom icon to be rendered as your omniauth provider icon, add an image asset to OpenProject and reference it in your settings.yml:

icon: "my/asset/path/to/icon.png"
