Just to clarify for my understanding. Let's assume the Session Timeout is maxed out to 14400 (10 days) and the Grace Period is set to 14399.
User Authenticates to portal on Monday at 8 AM and is associated for 1 hr. They then leave and do not come back until the following Monday at 8 AM. My understanding is with those values they do not need to auth again. Now that same User leaves and comes back that Friday. Do they need to re-auth at that point?
