Guys,
I have been trying to get the spring saml2 example (i.e. the spring-security-saml2-sample.war) working with SSOcircle (Note: I have also tried OpenAM/OpenSSO) and have run into lots of issues. The most obvious one is that when running the sample without modification and selecting "Select IDP:" http://idp.ssocircle.com. It fails with a HTTP Status 500 - The SAML Request is invalid. on the ssocircle server. The code in the sample does seem to download the IDP metadata from ssoCircle so I am confused as to where it goes wrong? Is there a bug in the latest SAML2 codebase or is there a patch that I need?
It's as if the latest SAML code does not form the appropriate saml2 request for ssocircle (even though the sample code is developed to work directly with ssoCircle).
I cannot find information on how to get it to work? Has anyone any pointers? I am running the spring-security-saml2-sample.war locally (do I need to deploy it on the internet)???

I have also attempted to get the sso working with the latest openam implementation and also cannot get it to work correctly?

Thanks in advance

Jerome
