1) No. There is a lot more required to log in via trusted auth than just having a valid ticket.
2) No. The ticket has a time limit. The trusted authentication process validates the ticket and timestamps it, then for each subsequent access request checks to see if the ticket has expired. If it has, the process starts all over again.
1) I have already setup trusted sites in Tableau Server. So any client with the trusted ticket will be able to load the View. Can the end user use this trusted ticket to login to Tableau server (in a new Browser window)?
2) I understand that the trusted tickets by default expire in 3 minutes, and we can change this time limit. But can the trusted ticket be redeemed more than once (probably on different machines), within that time limit?
