|---|
| | | 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 |

|---|
| | | 2. Run `mvn package` to build the plugin JAR |
|---|
| | | 3. Copy the JAR file generated in the `target` folder into the `providers` directory in your Keycloak server's root |
|---|

| | | # Configuration |
|---|
| | | ## 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. |
|---|
| | | |
|---|
| | | Enter `https://your.keycloak.host/auth/realms/master/protocol/cas` as the CAS URL into your SP. |
