Spring SAML, authentication entity is null

I have referenced the entire forum to understand the problem I was facing. I am still getting null authentication object

• Tomcat version - 8.0.44

• Java 1.7.0 I'm not sure if the security filter is called. See the Security Context section for details. It looks like I'm missing some configuration. Thanks in advance.
