The official CAS
5.3.0 GA was released on June 29th, 2018. Since then, the project has been moving forward with development of the next feature release that is tagged as
6.0.0. Note that this is a major release of the CAS software which may present significant changes in architecture, configuration or behavior. Please review the release policy to learn more about the scope of the release.
This post intends to highlight some of the improvements and enhancements packed into the fourth release candidate in the
You can read about the previous release candidate here.
Shake Well Before Use
We strongly recommend that you take advantage of the release candidates as they come out. Waiting for a
GA release is only going to set you up for unpleasant surprises. A
GA is simply a tag and nothing more. Note that CAS releases are strictly time-based releases; they are not scheduled or based on specific benchmarks, statistics or completion of features. To gain confidence in a particular release, it is strongly recommended that you start early by experimenting with release candidates and/or follow-up snapshots.
In order to start experimenting with release candidates, at any given time, you should be able to append
-SNAPSHOT to the CAS version specified in order to take advantage of snapshot builds as changes are made and published.

New & Noteworthy
Actuator Endpoint Ids
CAS actuator endpoints are named to be more consistent with Spring Boot guidelines, to remove startup warnings and prevents errors in future upgrades to Spring Boot
2.2.x. Previous endpoints that were created using kebab-case identifiers such as
spring-webflow are now switched over to use camel-case instead, such as
SMS via Groovy & REST
Sending SMS messages is now also possible via Groovy scripts or a REST API.
Dockerized CAS Overlay
The CAS WAR Overlay is equipped to build Docker images using
The CAS Command-line Shell gets a few upgrades to stay compatible with the most recent changes to the build, as well as a few new commands to generate crypto keys or encrypt/sign data, etc.
Each registered application in the registry may be assigned a set of environment names.
Support for reCAPTCHA v3 is now added to CAS.
Amazon Cognito Authentication
CAS is able to leverage Amazon Cognito for authentication.
CAS is able to leverage SOAP APIs for authentication.
JDBC Naming Strategy
Additional options are exposed to help remap database virtual table names to logical names either via static settings or Groovy scripts, when database schemas and queries are created. This allows one to translate CAS-provided table names to those that might work better with older or less forgiving database platforms that have restrictions on naming, etc.
- Small number of bug fixes to handle authorization correctly for delegated authentication.
- The configuration settings for Spring Cloud configuration modules for MongoDb, DynamoDb, JDBC, etc should properly be recognized by CAS again.
- The background job to reload CAS registered service is made conditional to only execute in case a reloadable storage option is registered.
- A number of additional test cases for AWS S3 functionality.
- Improvements to the crypto algorithm selection used to generate secure random numbers.
- CAS configuration can now be recognized via Groovy closures.
- Security response headers can support all CAS registered service definition types.
- Minor improvements to database attribute fetching and processing of SQL
- CAS configuration watch can operate on both the configuration directory and the standalone direct configuration file.
- CAS multifactor authentication via RADIUS gains the ability to enforce a limit on the number of allowed authentication attempts.
- Secret keys used for various signing and encryption operations can now properly be recognized via CAS settings.
- SAML2 SLO functionality receives a number of improvements to handle various forms of bindings.
