What is meta data in active directory?

Metadata in Active Directory refers to data that describes the properties and characteristics of objects within the directory, such as users, groups, and computers. This includes attributes like user names, security identifiers (SIDS), and permissions, as well as schema information that defines the structure of the data. Metadata is essential for the functioning of Active Directory, enabling efficient organization, retrieval, and management of directory objects. It also plays a crucial role in replication and consistency across domain controllers.
