We would like to prevent logon to SAP systems directly on single application server. Instead, we prefer that the users logon to SAP system by using load balancing method. Because of this we replaced single application server definitions with logon groups to SAPGUIs'. The problem is that we are not sure that all the definitions are replaced on SAPGUI for all users. Is there any indicator to see, whether the user is logged on the application server directly or by using LB, on the system?
