Hi Mohit,
Did you go from a Service Provider to the Gluu Server login? Or attempt to replicate on the login page alone?
We experience this without any delay on the login page. We just go from the Service Provider, to our login page (SP initiated auth request) and this happens from time to time. It is possible they may have had a session from a previous day and this is the first time they have attempted an SP-initiated login that day, but not that they have left the login page open as they are coming from elsewhere.
Is there any chance the above scenario would cause the same effect as having left the login page open for too long?
Is there anything that can be done to prevent landing on an "oops" page for an expired session? We need to maintain the SP initiated auth flow, yet give them a new session I suppose.
