System registry definitions

Use this information to learn about creating a user registry for particular systems.

A system registry definition is an entry that you create in Enterprise Identity Mapping (EIM) to represent and describe a distinct user registry within a workstation or server. You can create an EIM system registry definition for a user registry when the registry in the enterprise has one of the following traits:

• The registry is provided by an operating system, such as AIX^®, i5/OS™, or a security management product such as z/OS^® Security Server Resource Access Control Facility (RACF^®).
• The registry contains user identities that are unique to a specific application, such as Lotus Notes^®.
• The registry contains distributed user identities, such as Kerberos principals or Lightweight Directory Access Protocol (LDAP) distinguished names.

EIM lookup operations perform correctly regardless of whether an EIM administrator defines a registry either as system or application. However, separate registry definitions allow mapping data to be managed on an application basis. The responsibility of managing application-specific mappings can be assigned to an administrator for a specific registry.
