Enterprise Identity Mapping

Enterprise Identity Mapping (EIM) for iSeries is the OS/400® implementation of an IBM® infrastructure that allows administrators and application developers to solve the problem of managing multiple user registries across their enterprise.

Most network enterprises face the problem of multiple user registries, which require each person or entity within the enterprise to have a user identity in each registry. The need for multiple user registries quickly grows into a large administrative problem that affects users, administrators, and application developers. EIM enables inexpensive solutions for easier management of multiple user registries and user identities in your enterprise.

EIM is a mechanism for mapping and associating a person or entity to the appropriate user identities in various registries throughout the enterprise. EIM provides application programming interfaces (API) for creating and managing these identity mapping relationships and provides APIs that applications use to query this information. In addition, OS/400 uses EIM and Kerberos capabilities to provide a single sign-on environment.

iSeries Navigator, the iSeries graphical user interface, provides wizards to configure and manage EIM. In addition, administrators can manage EIM relationships for user profiles through iSeries Navigator.
