My client would like to implement code to only allow a user to login to Navision once (one current session at a time.) I've reviewed posts related to this topic, but they mostly seem to deal with being able to kill an additional session. I want to add code to the login form/table to check the Database information sessions table to see if the user is already logged in. However, I can't figure out where the source code is for the current sessions or what objec to add the logic to kick off the check when the user logs in. Any help would be appreciated!
