OU

/ˌoʊ-ˈjuː/

n. “A folder for organizing users and computers in Active Directory.”

OU, short for Organizational Unit, is a container within Active Directory used to organize users, groups, computers, and other OUs. It provides a hierarchical structure that helps administrators manage objects efficiently, delegate permissions, and apply GPOs (Group Policy Objects) selectively.

Key characteristics of an OU include:

DIT

/dɪt/

n. “The DNA of your directory.”

DIT, short for Directory Information Tree, is the hierarchical structure used by LDAP directories to organize and store entries. Think of it as a genealogical chart for network resources: users, groups, devices, organizational units, and other objects each occupy a branch, and every branch has a unique path. Each node in the tree is identified by a distinguished name (DN), which provides a globally unique address within the directory.
