Enterprise Identity Mapping
Enterprise Identity Mapping (EIM) is a technology for mapping identities within an enterprise. You can use EIM to create one-to-one mappings between individual user identities or for creating many-to-one mappings between a group of user identities in one user registry and a single user identity in another user registry.
Service tools user ID's and passwords
Service tools user IDs and password allows you to control access to dedicated service tools (DST) or system service tools (SST). Service tools user IDs are required to access DST, SST, and to use the System i Navigator functions for logical partition (LPAR) management and disk unit management.
Single Sign-on
Single sign-on uses network authentication service for authentication and Enterprise Identity Mapping (EIM) to map from one user identity to another user identity; for example, you can map from an authenticated Windows user identity to an appropriate i5/OS user profile for authorization purposes.
