title: WSO2 IS login with Radius / Kerberos
body: <p>The picture bellow shows the architecture that I need to deploy, and it explains my problem.</p>
  
  <p>I already designed a sub system that contains a set of applications (web services, web applications) deployed in apache tomcat. To provide the SSO functionality to my sub-system I used the WSO2 Identity Server with SAML2.0 to authenticate users and get access to all sub-system applications.</p>
  
  <p>This sub system is destined to be integrated into enterprises environment and work together with enterprise components. Now I need that enterprise users get access to my applications (of sub-system) there is two cases: </p>
  
  <ol>
  <li><p>Connect WSO2 Identity Server to the enterprise LDAP, the WSO2 IS
  authenticate users by requesting the enterprise LDAP. <strong>This is not
  recommended</strong>.</p></li>
  <li><p>Make WSO2 IS to work with the enterprise authentication server
  (Kerberos, Radius, CAS, etc.), the WSO2 :<strong>Brokred Authentication</strong>.</p></li>
  </ol>

  <p><strong>How to authenticate automatically to wso2 IS with a Kerberos. ticket obtained from kerberos authentication (or Radius) ?</strong></p>
