Description of problem: Channel Binding for the Kerberos Protocol is implemented incorrectly, causing interopability problems with Windows Server 2008/Internet Explorer. Version-Release number of selected component (if applicable): java-1.6.0-openjdk-1.6.0.0-1.41.1.10.4 Oracle has released a patch to this problem, but it is not included in openjdk as provided by Redhat. How reproducible: * Setup a AD Domain with W2K8 * Microsoft IE patch KB974455 enabled "Extended Protection" for Integrated Windows Authentication is installed (default now!) * Add RHEL6 Client to AD Domain * Install tomcat and for instance spnego.sf.net and configure a Web Kerberos SSO (or CAS from jasig or shibboleth from internet2.org ) * Use the Internet Explorer to authenticate a websession * You get this java exception. GSSException: Channel binding mismatch (Mechanism level: ChannelBinding not provided!) More and background information is provided in ticket http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=830 Additional info: Please add the patch which is provided in the icedtea bugzilla to openjdk.
I have requested a backport upstream: http://mail.openjdk.java.net/pipermail/jdk6-dev/2011-December/002602.html Once there, I will request for IcedTea and we can then do RHEL builds.
