To delete an identifier association, you must be connected to the Enterprise Identity Mapping (EIM) domain in which you want to work and you must have the EIM access control required by the type of association that you want to delete.
To delete an identifier association, complete the following steps.
The only way to define a user identity to EIM is when you specify the user identity as part of creating an association, either an identifier association or a policy association. Consequently, when you delete the last target association for a user identity (whether by removing an individual target association or by removing a policy association), that user identity is no longer defined in EIM. Consequently, the user identity name and any lookup information for that user identity is lost.
