An introduction to Active Directory

Active Directory (AD) is a Microsoft product that consists of several services which run on Windows Server in order to manage permissions & access to your networked resources.

Active Directory stores data as objects. An object is a single element, such as a user, group, application or device, such as a printer. Objects are normally defined as either resources — such as printers or computers — or security principals — such as users or groups.

Active Directory categorises objects by name and attributes. A good example of this might be the user’s name string, along with other information associated with them, such as passwords and Secure Shell (SSK) keys.
