We have upgraded Gluu from version 4.2.3 to 4.3.1, the upgrade was successful using the https://raw.githubusercontent.com/GluuFederation/community-edition-package/master/update/4.3.1/upg4xto431.py script We have verified that the login has not been affected and there is no problem related accesing our platforms, but we have noticed an issue when we log out. It seems that the front channel logout process is not working because if we are logged in on two or more platforms with the same session, when we log out from one platform, the session is not being logged out from the other ones. We noticed that when we fire the log out process, only one session indicator (iframe) is displayed on the screen corresponding to the platform where the logout was fired. The other platforms sessions are not affected at all. Before performing the update, the described issue did not happen on version 4.2.3, so we would like to know if this new version added any change on the log out process or what we should do to fix this issue. Thank you
