Organizations that have applications that require a directory for storing application data can use Active Directory Lightweight Directory Services (AD LDS) as the data store. AD LDS runs as a service that is independent of a domain's directory service. AD LDS does not require deployment on an Active Directory domain controller. In addition, you can install multiple instances of AD LDS and run them concurrently on a single computer.
Note: AD LDS was previously known as Active Directory Application Mode (ADAM).
The following is a list of the managed entities that are included in this managed entity:
If there is a change to the configuration of an Active Directory Lightweight Directory Services (AD LDS) instance, the change must be registered with the instance's internal database as well as with the databases of any replication partners that are configured. Such updates are especially important when replication partners exist, because a local instance cannot receive any updates from its replication partners until the change is registered by the replication partners in their respective databases. The configuration changes that must be recorded and replicated include the following:
Note: AD LDS provides services by using the security credentials of a user account. A user account that a service uses is commonly known as a service account.
When Active Directory Lightweight Directory Services (AD LDS) is running on a computer that is joined to a domain, the AD LDS instance creates a serviceConnectionPoint (SCP) object in the domain so that other computers in the domain can locate the AD LDS instance.
