Active directory lightweight directory services wiki

Active Directory Lightweight Directory Services (AD LDS), formerly known as Active Directory Application Mode (ADAM), is a directory service that runs as a stand-alone application. Unlike Active Directory Domain Services (AD DS), which stores data in the form of a hierarchical namespace, AD LDS uses a flat namespace. AD LDS is designed to provide directory services for applications that use LDAP (Lightweight Directory Access Protocol), such as Microsoft Exchange Server and Microsoft Internet Authentication Service (IAS).

Active Directory Lightweight Directory Services (AD LDS) is a directory service that provides a flexible approach to directory storage and management for application developers. AD LDS runs as a service on Windows Server operating systems. It stores data in an extensible schema, which can be customized to meet the directory needs of the application. AD LDS provides the same core directory services features as Active Directory Domain Services (AD DS), such as security and authentication, but it does not require the deployment of domains or domain controllers.

Active Directory Lightweight Directory Services (AD LDS) provides a flexible means of storing and replicating directory data for applications, services, and users that requires directory data outside of the domain namespace. AD LDS runs as a service on Windows Server operating systems. Because AD LDS uses the same code base as Active Directory Domain Services (AD DS), it is sometimes referred to as Active Directory Application Mode (ADAM).
