Abstract
An identification system that may be used in heterogeneous computing environments provides a fail-free path to providing identifiers from a single canonical namespace. Objects or gateways requiring an identifier for access are accessed using an identifier for the canonical namespace. If an entity requests access using an identifier from another namespace, an external database is consulted to determine if a mapping exists for the identifier to another identifier the canonical namespace. If no mapping exists, or the external database is unavailable, then an identifier is automatically generated in the canonical namespace and is used for the access. An internal database is updated with the automatically generated identifier, providing a mechanism to add mappings without administrative intervention. To access resources requiring an identifier from another particular namespace, a canonical namespace identifier may be mapped to another identifier in the particular namespace, or a generic identifier may be used.
