Central Authentication Service (CAS)


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

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 customizations to further ease future upgrades and maintenance.

Download Maven Central

  • Binary releases may be downloaded from here.
  • CAS artifacts are published through the Maven Central Repository.
  • A snapshot of the codebase's master branch 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

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.

Documentation License


  • CAS Addons is an open source collection of useful CAS server extensions.
