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 **missing**: +* SAML request/response [CAS 3.0 - optional] +* Proxy ticket service and proxy ticket validation [CAS 2.0] + +The following features are out of scope: +* Long-Term Tickets - Remember-Me [CAS 3.0 - optional] + +## Compatibility + +The CAS plugin has been tested against the same Keycloak version as the plugin version. + +As a rule of thumb plugin version should **match your Keycloak version**. + +## Installation + +Installation of a compatible plugin version is simple and can be done without a Keycloak server restart. + +1. Download the latest release compatible with your Keycloak version from the [releases page](https://github.com/jacekkow/keycloak-protocol-cas/releases). +2. Copy the JAR file into the `standalone/deployments` directory in your Keycloak server's root. + +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/auth/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. +It is licensed under the Apache License 2.0. + +This repo is a fork of https://github.com/Doccrazy/keycloak-protocol-cas +and includes changes for Keycloak 8 and newer that were not merged by the owner for half a year. + +## References + +[1] https://www.keycloak.org/ +[2] https://issues.jboss.org/browse/KEYCLOAK-1047 (Support CAS 2.0 SSO protocol) +[3] https://apereo.github.io/cas/4.2.x/protocol/CAS-Protocol-Specification.html +[4] https://keycloak.gitbooks.io/server-developer-guide/content/topics/providers.html -- Gitblit v1.9.1
