The following content is outdated:
I know that there are many JBoss users hoping to see SAML v2.0 support in JBossAS. We will get there once OpenSAML v2.0 development by Internet2 middleware reaches some stable milestone. What I like about OpenSAML is that it provides a library to build components that are saml aware. A nice thing is that v2 will contain bindings like http redirect, http post etc that we can reuse.
Well, I am just thinking that there is broad expectation of saml2 support in JBoss. Why don't you tell me by leaving a comment?
UPDATE (Feb 09): Use the Identity Community Platform
UPDATE (Oct 08): We are working on a common identity project at JBoss. As part of this project, we will provide you Identity Management as well as Federated Identity stack (SAML etc).
