title: Spring SAML - AuthResponse doesn't come to SP if it honors only https
body: <p>I am using spring-saml extension and tried to create a POC in tomcat when tomcat only accepts the https (yes no http) and on the web entry, end user it taken to the IDP's screen and after authentication, never comes back to the SP pages because SP never gets the AuthResponse from iDP.</p>
  
  <p>Here is the spring-saml security configuration:</p>

  <p>I am using the SSOcircle as IDP in this case.</p>
  
  <p>when I ask tomcat to accept the http also and change the SP's end point url to http (and port 8080) instead of https (and port 8443) - SSO work very well.</p>
  
  <p>IDP also only accepts the https protocal, which seems work well for it.</p>
  
  <p>What could be the reason of this not working on SP side for https?</p>
