Why Use Active Directory Lightweight Directory Services?
Active Directory Lightweight Directory Services (AD LDS) has both functional benefits and operational benefits for developers who create or adapt directory-enabled applications.
Developers using AD LDS have access to the following functional benefits:
- AD LDS uses the same directory service technology as Active Directory. This means there is a common framework for both the network operating system (NOS) services of Active Directory and the application services of AD LDS.
- Use of the same directory service technology increases reusability of design and code between Active Directory and AD LDS.
- AD LDS increases the scalability of directory services by separating the NOS services from the application services.
- Multiple instances of AD LDS, each tailored to a specific application, can run on a single AD LDS installation.
- Each AD LDS configuration set has a separate schema, independent of the Active Directory schema.
- AD LDS can use X.500-style naming contexts, such as O=Fabrikam and C=US.
- To increase application security, AD LDS can use Windows security principals for authentication and access control.
- Development for AD LDS can occur on Microsoft Windows XP Professional as well as on the Windows Server 2003 operating systems.
- AD LDS is easy to deploy. Installation and setup are simple.
- AD LDS can be installed without affecting Active Directory.
- AD LDS can be reinstalled or restarted without a restart.
- AD LDS uses the same administrative model as Active Directory.
- AD LDS increases reliability by separating application directory services from NOS directory services.
