The use of Central User Administration (CUA) if you are an SAP customer is outdated. This user management method is over 20 years old. Managing users with CUA is time-consuming and painful, setting users up in an Enterprise environment.
The Benefit of an IDM implementation using SAP IDM NW 8 for On-Premise or Identity Provisioning Services (IPS) allows you the flexibility to manage systems across the enterprise.
Clients who are using On-Prem Only systems who prefer to remain in this environment can use SAP IDM NW 8, which supports on-premise provisioning, which allows you to manage user onboarding, transfers, and off-boarding from one central system.
Clients who are using Cloud systems and have moved away from On-Premise systems can implement the SAP Identity Provisioning Service, which allows you to manage all your cloud applications from one central system. The features for provisioning allows you to manage onboarding, transfers, and off-boarding from one central system.
The recommended approach can be as simple as a two tied landscape where all of your nonproduction systems are managed by your nonproduction IDM solution. Your Production IDM solution manages your Production systems regardless of system type (SAP, Non-SAP, HR, Active Directory, Microsoft, etc.)
The future of Identity Management manages your Identity of each user more effectively and securely where access is granted based on job function and who needs access to which areas of each system.
