title: SAML2 IDP session timeout and SLO
body: <p>We have a SAML2 IDP configured with session inactivity time-out as 30 min. After the Single Sign on the user is successfully logged on into the SP. Now the SP is also configured for SAML Single Logout (SLO). It appears that even as users are working in the SP app, the session time out happens. I was wondering if this is happening due to session inactivity set up @ IDP. I would like to understand how the IDP knows that the user sessions are active @ SP so that it doesnt issue a SLO. Any ideas ?</p>
