This plugin for Keycloak Identity and Access Management (http://www.keycloak.org) adds the CAS 3.0 SSO protocol as an available client protocol to the Keycloak system. It implements the required Service Provider Interfaces (SPIs) for a Login Protocol and will be picked up and made available by Keycloak automatically once installed.
The following CAS features are currently implemented:
* CAS 1.0/2.0/3.0 compliant Login/Logout and Service Ticket Validation
* Single Logout (SLO)
* Filtering of provided service against configured redirect URIs
* JSON and XML response types
* Mapping of custom user attributes to CAS assertion attributes
The following features are currently missing:
* #2: Proxy ticket service and proxy ticket validation [CAS 2.0]
* #1: SAML request/response [CAS 3.0 - optional]
The following features are out of scope:
* Long-Term Tickets - Remember-Me [CAS 3.0 - optional]
mvn package to build the plugin JARtarget folder into the standalone/deployments directory in your Keycloak server's rootTo use the new protocol, you have to create a client within Keycloak as usual.
Important: Due to KEYCLOAK-4270, you have to select the openid-connect protocol when creating the client and change it after saving.
As the CAS protocol does not transmit a client ID, the client will be identified by the redirect URIs (mapped to CAS service). No further configuration is necessary.
Enter https://your.keycloak.host/auth/realms/master/protocol/cas as the CAS URL into your SP.
This plugin was implemented from scratch to comply to the official CAS protocol specification, and is based heavily on the OpenID Connect implementation in Keycloak.
