Yes, it is possible but you have to do it through the startup script. So basically we will use AD to login but once they are logged in we will check to see if they are already logged in and if they are we will log them out. The startup script will look something like this:sessions = system.util.getSessionInfo("User01", "ProjectName")
if len(sessions) > 1:
system.gui.messageBox("You can only be logged in once")
system.security.logout()By the way you can edit the startup script from the designer under Project > Event Scripts (Client) from the menu at the top. Select the Startup tab and put the script in.
