Object

A particular set of attributes that represents something concrete, such as a user, a printer, or an application. The attributes hold data describing the thing that is identified by the object. Attributes of a user might include the user’s given name, surname, and e-mail address. The classification of the object defines which types of attributes are used. For example, the objects classified as users might allow the use of attribute types like common name, telephone number, and e-mail address, whereas the object class of organization allows for attribute types like organization name and business category. An attribute can take one or more values, depending on its type.

Object identifier (OID)

A globally unique identifier (GUID), which is assigned by the Directory System Agent (DSA) when the object is created. The GUID is stored in an attribute, the object GUID, which is part of every object. The object GUID attribute can’t be modified or deleted. When storing a reference to an Active Directory object in an external store (for example, a database), you should use the object GUID because, unlike a name, it won’t change.

Organizational unit (OU)

A container object in Active Directory used to separate computers, users, and other resources into logical units. An organizational unit is the smallest entity to which Group Policy can be linked. It is also the smallest scope to which administration authority can be delegated.
