1.Created an SSOCircle account as mentioned in .
2.Configured KeyStore & Truststore as in 
3.Modified SAML 2.0 Handler and Referrer filter configuration as mentioned in

5.Modified "Apache Sling Authentication Service" configuration to uncheck the checkbox against "Allow Anonymous Access"
6.Modified "Day CQ Root Mapping" configuration to point to my applcications home page.(/content/<myapps>/homepage.html)
7.Add a logout link to my page header <a href="https://forums.adobe.com/system/sling/logout">
When I access my page for first time, I was taken to the SSO Circle login page, I entered the credentials and was taken to my applications home page. On clicking logout , I was taken to the SSO cirlce login page.
Can someone guide me what I am missing / What have I done wrong in integrating AEM with SAML.
My requirement is Whenever user clicks logout button, he should be taken back to IDP login page. He should be able to see my protected pages only after entering the credentials again .(Even clicking on browser back button , he should be taken to IDP login page).
Note: Please let me know if anymore details are required.
