Apache Kerby is a new subproject of Apache Directory that aims to provide a complete Kerberos solution in Java. Version 1.0.0-RC1 has recently been released and is available for testing. Apache Kerby consists of both a KDC as well as a client API, that is completely independent of the GSS API that comes with Java. A key selling point of Apache Kerby is that it is very easy and fast to setup and deploy a KDC. It is possible to set up a KDC completely in code, without having to edit any configuration files or configure any system properties.
Let's see how this is done by looking at a project I created on github:
- cxf-kerberos-kerby: This project contains a number of tests that show how to use Kerberos with Apache CXF, where the KDC used in the tests is based on Apache Kerby.
AuthenticationTest also includes unit tests for getting a service ticket from the Kerby KDC using the Java GSS API as well as the Kerby client API. Using the Kerby client API is as simple as this:
