HttpSession returned null object for SPRING_SECURITY_CONTEXT

I am trying to integrate the Spring Saml library into a sample web application using Shibboleth as an IDP. I can load the login page, log in and show the index page.

The problem is that when I click on other links, webapp redirects me to the login page, then IDP recognizes me and redirects to the requested page (if it’s very difficult to see on the network). This is similar to the fact that I did not log into the system for Spring security.

I checked the log and I found this:

org.springframework.security.web.context.HttpSessionSecurityContextRepository - HttpSession returned a null object for SPRING_SECURITY_CONTEXT org.springframework.security.web.context.HttpSessionSecurityContextRepository - No new SecurityContext will be created from EmailContext.

This is web.xml

Any idea?

I had the same problem. After the debugging realized that the SecurityContext is cleared before it is saved. After googling, I found this: https://jira.springsource.org/browse/SEC-2027 Moving to spring version 3.1.2 for security solved it for me.

I hope this helps someone.

If you are not using Spring, or you can try something that works first, and go to Spring later, here is a good tutorial. I tried this, it works:

The author of the blog Philip is very responsive, you can get clarifications from him, if necessary.
