Security Settings | Common Tweaks: Hide concurrent login banner.
Hide concurrent login banner:
We will show a banner in the bottom right, when the same user logs in from another instance. Some customers want to disable these alerts. To modify this behaviour, connect to the database and run the following query:
update GlobalConfig set paramvalue='false' where parameter='NOTIFY_LAST_LOGIN_DETAILS';
Restart the application for the changes to take place.
