|---|
| | | 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. |
|---|
| | | |
|---|
| | | # Features |
|---|
| | | The following CAS features are currently implemented: |
|---|
| | | * CAS 1.0/2.0/3.0 compliant Login/Logout and Service Ticket Validation |
|---|
| | | * 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] |
|---|
| | | * SAML request/response [CAS 3.0 - optional] |

| | | # Installation |
|---|
| | | 1. Clone or download this repository (pre-compiled releases will follow!) |
|---|
| | | 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 |
|---|
| | | 4. Restart Keycloak |
|---|
| | | |
|---|
| | | # 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. |
|---|
| | | |
|---|
| | | # 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. |
