title: SSL configuration issue with Spring-SAML
body: <p>I'm trying to set up a SP based on "spring-security-saml2-sample", but when I deploy the WAR file on Tomcat I get the following exception:</p>

  <p>I understand that the exception is caused because the IdP (Oracle OIF) self-signed certificates are not correctly imported in keystore. Federation URL is protected with SSL so I've already included the SSL certificate in the keystore (samlKeystore.jks). I've also included OIF certificate used for signing SAML assertion responses.</p>
