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. + + + +## Features + 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 **curently missing**: -* Proxy ticket service and proxy ticket validation [CAS 2.0] -* Long-Term Tickets - Remember-Me [CAS 3.0 - optional] +The following features are **missing**: * SAML request/response [CAS 3.0 - optional] +* Proxy ticket service and proxy ticket validation [CAS 2.0] -# Installation -1.

Restart Keycloak +The following features are out of scope: +* Long-Term Tickets - Remember-Me [CAS 3.0 - optional] -# Configuration -To use the new protocol, you have to create a client within Keycloak as usual. -**Important: Due to [KEYCLOAK-4270](https://issues.jboss.org/browse/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. +## Compatibility -Enter `https://your.keycloak.host/auth/realms/master/protocol/cas` as the CAS URL into your SP. +The CAS plugin has been tested against the same Keycloak version as the plugin version. -# Disclaimer -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. +As a rule of thumb plugin version should **match your Keycloak version**. + +## Installation + +Quarkus is the default distribution method of Keycloak 17.0.0 and newer. For legacy installations using WildFly, please refer to the [old README](https://github.com/jacekkow/keycloak-protocol-cas/blob/16.1.1/README.md). + +1. Download the latest release compatible with your Keycloak version from the [releases page](https://github.com/jacekkow/keycloak-protocol-cas/releases). +2. Put the downloaded JAR file into the `providers/` directory inside Keycloak installation folder. +3. Stop the Keycloak server. +4. (Re-)build the installation using `kc.sh build` command. +5. Start the Keycloak: `kc.sh start` + +Remember to update plugin artifact with each Keycloak server upgrade! + +## Configuration + +To use the new protocol, you have to create a client within Keycloak as usual, selecting `cas` as protocol. +As there is no client ID indication in protocol, the client will be identified by the redirect URIs +configured in Keycloak. + +Enter `https://your.keycloak.host/realms/master/protocol/cas` as the CAS URL into your SP. +This assumes that you use the default `master` realm - if not, modify the URL accordingly. + +Note that some client implementations require you to enter login and validate URLs, not CAS URL! +This manifests with "Page Not Found" error on login attempt +(see [issue #27](https://github.com/jacekkow/keycloak-protocol-cas/issues/27) for example). +In such case append `/login` to the CAS URL to get the "login URL". +Similarly append `/serviceValidate` to get the "validate URL". + +## Disclaimer + +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.
