GB/T 16264.1-2008

This standard defines the fundamental concepts, models, and services for a directory system in an Open Systems Interconnection (OSI) environment, essentially specifying how a distributed directory (like an X.500 directory) should function. It is applied in the design and implementation of network directory services, such as those used for managing user identities, network resources, and certificates in enterprise IT infrastructures or public key infrastructures (PKI). The standard provides the foundational framework for interoperability between different directory systems, ensuring consistent access and management of directory information across heterogeneous networks.
