title: How to get the login-page of openAM when the iPlanetDirectoryPro is disabled? Now is 403 forbidden page
body: <p>openAM 13.0 tomcat8.3 apache 2.4 centos 7.2 firefox</p>
  
  <p>When I ask "www.example.com:8000/demo.html", it is ok.
  I get the login-page of openAM, then I input the name and password, return the page of "www.example.com:8000/demo.html".</p>
  
  <p>However, I restart the openAM after I have got the page of "www.example.com:8000/demo.html", then I ask "www.example.com:8000/demo.html", return "403 forbidden". Why?</p>
  
  <p>Then, I found that the iPlanetDirectoryPro in cookie is disabled. If there is a disabled iPlanetDirectoryPro in the cookie, openAM returns a "403 forbidden". But there is not a iPlanetDirectoryPro in the cookie, openAM redirect login-page of the openAm.</p>
  
  <p>I hope that openAM redirect login-page when there is a disabled iPlanetDirectoryPro in the cookie. How can I do it?</p>
