Analysis of AD LDS Lightweight Directory Service in Windows 2008

The Lightweight Directory Service (AD LDS) role is a fully functional and easy to install and deploy directory service. It provides a specialization for applications and can be individually configured and managed. Running as a non-operating system service allows multiple AD LDS instances to run concurrently on a server and each instance can be independently configured to serve multiple applications. AD LDS also does not need to be on a domain controller (relying on Active Directory Service (AD DS)) for deployment.

  

An instance of AD LDS is a single running copy of AD LDS. Unlike the AD DS service multiple copies of AD LDS can be run by colleagues on the same computer. When replicating instances from multiple servers this can improve availability and achieve load balancing. Each instance of AD LDS has a separate directory a unique service name and a unique service description assigned when the instance is created.

Each instance of AD LDS can contain one or more application directory partitions to save application data. All application directory partitions in an AD LDS directory instance share a single structure which is used to define the objects and attributes that can be stored in the directory. When creating an application directory you can choose to create an empty application partition or you can copy one or more application directory partitions from an existing AD LDS instance.

AD DS and AD LDS have many similarities in their usage. In any case they still have many important differences for their different tasks. The content of this lesson only needs to compare AD DS and AD LDS.

  o They all use the LDAP protocol and support LDAP client connections.

  o Use a multi-host replication engine to distribute replicated data.

  o Supports the delegated management of partitions organizations (OUs) groups roles or users.

  o Use Extensible Storage Engine (ESE) for data storage.

  AD DS and AD LDS each have a clear and unique purpose and they have several differences. AD DS was initially designed to provide services for the operation management and audit of the enterprise. AD LDS is designed to provide a sound and simple tool and infrastructure for other applications to realize the data storage guarantee for management auditing and other functions.
