Welcome to the home of the Central Authentication Service project, more commonly referred to as CAS. The Central Authentication Service (CAS) is the standard mechanism by which web applications should authenticate users.
CAS provides enterprise single sign-on service:
- An open and well-documented protocol
- An open-source Java server component
- A library of clients for Java, .Net, PHP, Perl, Apache, uPortal, and others
- Integrates with uPortal, BlueSocket, TikiWiki, Mule, Liferay, Moodle and others
- Community documentation and implementation support
- An extensive community of adopters
CAS requires J2SE 1.6, J2EE1.3 and a servlet container that can handle JSP 2.0 (e.g., Tomcat 5.0.28)
It is recommended to build and deploy CAS locally using the Maven War Overlay method. This approach does not require the adopter to explicitly download any version of CAS, but rather utilizes Maven's overlay mechanism to combine CAS original artifacts and local customozations to further ease future upgrades and maintenance.
- Binary releases may be downloaded from here.
- CAS artifacts are published through the Maven Central Repository.
- A snapshot of the codebase's
masterbranch may be downloaded from here. - Snapshot artifacts are also published through the Sonatype snapashots repository under the group id
org.jasig.cas. - The codebase may also be cloned using a Git client via the following command:
git clone git@github.com:Jasig/cas.git
Note: If building CAS from the source, running the test cases currently requires an active Internet connection. Please see the maven docs on how to disable the tests.
- CAS Protocol
- CAS User Manual
- Javadocs
Javadocs may also be created locally using the Maven command:
mvn clean site site:stageand will then be available at thetarget/stagingfolder of the root project directory. - Release Notes
- CAS Addons is an open source collection of useful JASIG-CAS server addons.
