I am doing some research on a solution that may or may not exist for our scenario. At the moment we have several different ABAP backends that users log into (ECC, CRM, BW, SCM, SNC, etc.) and we are trying to find an "SSO" solution that will require the user to only log into one system through SAPGui and then be trusted to access the other systems that they are assigned to without having to log in separately to 3 or 4 different systems. Is IDM something that would be useful for us? I've read through much of the documentation, but am having trouble finding specific information on our scenario. Any help would be greatly appreciated.
