title: Single Sign On using Tomcat
body: <p>We are thinking about moving from WebSphere to Tomcat.  In WebSphere, we use <a href="http://en.wikipedia.org/wiki/IBM_Lightweight_Third-Party_Authentication" rel="nofollow noreferrer">LTPA</a> to achieve single sign on between the different applications (running in different physical servers).</p>
  
  <p>What is the best way to get single sign-on between 2 physical machines in Tomcat?</p>
