System Landscape with LDAP Directory

A directory service is suited to integrating external systems and SAP systems (ABAP and Java) into a heterogeneous system landscape.

Options for including J2EE Engines in the system landscape are as follows:

·        LDAP Directory with J2EE Engine(s)

J2EE Engine without associated ABAP system (such as an SAP NetWeaver Portal), which is connected directly to the directory service.

·        LDAP Directory with ABAP System(s)

J2EE Engine with associated ABAP system, which is connected to the directory service using Central User Administration (such as Employee Self-Service).
