Concrete identification enables Adaptive Server to verify chains of ownership between procedures, views, and triggers and the objects they reference in other databases. When a user creates an object, Adaptive Server associates both the owner’s database user ID (UID) and the object creator’s login name with the object in sysobjects. This information concretely identifies the object as belonging to that user, which allows Adaptive Server to recognize when permissions on the object can be granted implicitly. This may affect older applications that have cross-database queries, giving you permission errors.
See Chapter 17, “Managing User Permissions” in System Administration Guide: Volume One for more information about concrete identification.
