title: Where is WIF Security Token timeout coming from?
body: <p>One of the events on the <code>SessionAuthenticationModule</code> class is <code>SessionSecurityTokenReceived</code>.  This allows us to look at the session token that we receive from AD FS.  The <code>SessionToken</code> as two properties called <code>ValidFrom</code> and <code>ValidTo</code>.  In the configuration we have right now, taking the difference between these two is 1 hour.  I have looked through settings in AD FS, but I have been unable to find out how to change this value.  Does anyone know where it is?</p>
