A policy association provides a means to directly define a relationship between multiple user identities in one or more registries and an individual target user identity in another registry. Policy associations use Enterprise Identity Mapping (EIM) mapping policy support to create many-to-one mappings between user identities without involving an EIM identifier. Because you can use policy associations in a variety of overlapping ways, you need to have a thorough understanding of EIM mapping policy support before you create and use policy associations. Also, to prevent potential problems with associations and how they map identities, you need to develop an overall identity mapping plan for your enterprise before you begin defining associations.
Whether you choose to create identifier associations, create policy associations, or use a mix of both methods depends on your EIM implementation needs.
How you create a policy association varies depending on the type of policy association. To learn more about how to create a policy association, see:
