I'm using spring-saml2-sample app to connect to a Shibboleth IDP. I finally managed to send the correct saml request to the IDP using http post, but after login I get back the following on the SP side:
org.springframework.security.web.context.HttpSessionSecurityContextRepository - HttpSession returned null object for SPRING_SECURITY_CONTEXT
There was a post like this one where the problem was resolved by moving to spring security version 3.1.2, but that is the version that comes with the saml2-sample app. Am I missing something? I haven't changed much in the saml2-sample app, the web.xml is the same, libs are the same.
Any help will be very appreciated.
