Active Directory is a user management tool for centrally managing the functions and user information of Windows PCs using the domain authentication mechanism. It was introduced from Windows Server 2000 and has been introduced by many companies and educational institutions to this day. As a merit of introducing Active Directory, the system administrator can collectively manage various information and status related to the personal computer, which can greatly reduce the management effort.
