Active Directory (AD)<\/b> is a directory service developed by <\/span>Microsoft<\/b> to manage and organize network resources, including users, devices, and applications, within a centralized environment. It is commonly used in enterprise networks to provide authentication, authorization, and directory services.<\/span><\/p><\/div>\r\n\t\t\t\t<\/div>\r\n\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t<\/div>\r\n\t\t\t\t\t\t\t<\/div>\r\n\t\t<\/section>\r\n\t\t\t\t

  1. Domain<\/b>: The core unit of AD, representing a group of objects such as users, devices, and applications within a single namespace.<\/span><\/li>
  2. Domain Controller (DC)<\/b>: A server that hosts AD services and handles authentication and authorization requests.<\/span><\/li>
  3. Organizational Units (OUs)<\/b>: Containers within a domain used to organize and group objects like users and computers.<\/span><\/li>
  4. Objects<\/b>: Entities stored in AD, such as users, computers, printers, and groups.<\/span><\/li>
  5. Schema<\/b>: The blueprint that defines the types of objects and their attributes in the directory.<\/span><\/li><\/ol><\/div>\r\n\t\t\t\t<\/div>\r\n\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t<\/div>\r\n\t\t\t\t\t\t\t<\/div>\r\n\t\t<\/section>\r\n\t\t\t\t

    1. Authentication<\/b>: When a user logs in, AD verifies their credentials (username and password) against its database.<\/span><\/li>
    2. Authorization<\/b>: Based on policies and permissions, AD determines what resources the user can access.<\/span><\/li>
    3. Replication<\/b>: Changes made to one Domain Controller are replicated to others, ensuring consistency across the network.<\/span><\/li>
    4. LDAP Protocol<\/b>: AD uses <\/span>Lightweight Directory Access Protocol (LDAP)<\/b> to interact with directory services.<\/span><\/li>
