Enterprise Identity Mapping concepts

A conceptual understanding of how Enterprise Identity Mapping (EIM) works is necessary to fully understand how you can use EIM in your enterprise. Although the configuration and implementation of EIM APIs can differ among server platforms, EIM concepts are common across IBM® eServer platforms.

Figure 1 provides an EIM implementation example in an enterprise. Three servers act as EIM clients and contain EIM-enabled applications that request EIM data using EIM lookup operations Refer to number 6 in Figure 1. The domain controller Refer to number 1 in Figure 1 stores information about the EIM domain Refer to number 2 in Figure 1, which includes an EIM identifier Refer to number 3 in Figure 1, associations Refer to number 4 in Figure 1 between these EIM identifiers and user identities, and EIM registry definitions Refer to number 5 in Figure 1.
