| | | 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. |

| | | ## Installation |
| | | The CAS plugin has been tested against the following Keycloak versions. Please ensure your version is compatible before deploying. |
| | | Please report test results with other versions! |
| | | |
| | | Plugin version | Keycloak 2.5.x | Keycloak 3.0.x | Keycloak 3.1.x | Keycloak 3.2.x |
| | | ------------ | ------------- | ------------- | ------------- | ------------- |
| | | 1.0.0 | :white_check_mark: | :white_check_mark: | :white_check_mark: | :x: |
| | | |
| | | 1. Download the latest release compatible with your Keycloak version from the [releases page](https://github.com/Doccrazy/keycloak-protocol-cas/releases) |
| | | 2. Copy the JAR file into the `standalone/deployments` directory in your Keycloak server's root |
| | | 3. Restart Keycloak (optional, hot deployment should work) |
| | | |
| | | ## 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 may have to select the `openid-connect` protocol when creating the client and change it after saving. This has been fixed in Keycloak 3.0.0.** |
| | | 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. |
| | | |
| | | ## 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. |
