In Active Directory, container structures are organized into four main divisions: Organizational Units (OUs), Domains, Sites, and Forests. OUs are used to create a hierarchical structure for managing users, groups, and resources within a domain. Domains represent the core units of security and administrative boundaries, while Sites are used for network topology and replication management. Forests are the highest level of the structure, encompassing multiple domains and providing a shared schema and global catalog.
