Hi,
What happens if you open third tab and try to access some application which is using first account?
** - When opening a third tab you will get the correct cookies of the loggedin user for that specific application (client). **
Using prompt=login will create a situation as I described in the docs link above, where one browser session has multiple sessions. Right now, Gluu only supports one active session per browser session, not per tab.The best way to handle this is to do your other session in incognito mode so cookies are not shared across the session. I see Google is handling this much better now, so I'll add it as a feature request in the upstream open source to revisit this session behavior.
** - Okay understoond, thanks.**
