The linkTargets IDMXUser view option allows the caller to specify the list of resources that should be targeted for linking. When using forms, the list can be provided as a form property with the same name. Form properties are assimilated into view options when the IDMXUser view is checked in.
A link correlation rule selects resource accounts that the user might own. Given the view of the user, a link correlation rule returns an identity, a list of identities, or an option map.
If the rule returns an option map, then the view handler uses the map to look for resource accounts and obtains a list of identities that satisfy these options. For example, the searchFilter option of the getResourceObjects FormUtil method can be used to pass a search filter to an LDAP resource adapter.
A link correlation rule must have the authType attribute set to SPERule with the subtype set to SUBTYPE_SPE_LINK_CORRELATION_RULE.
