Please explain how this feature is possible?
Active Directory Lightweight Directory Services
Active Directory Lightweight Directory Service (AD LDS), formerly known as Active Directory Application Mode, can be used to provide directory services for directory-enabled applications. Instead of using your organization’s AD DS database to store the directory-enabled application data, AD LDS can be used to store the data. AD LDS can be used in conjunction with AD DS so that you can have a central location for security accounts (AD DS) and another location to support the application configuration and directory data (AD LDS). Using AD LDS, you can reduce the overhead associated with Active Directory replication, you do not have to extend the Active Directory schema to support the application, and you can partition the directory structure so that the AD LDS service is only deployed to the servers that need to support the directory-enabled application.
Install from Media Generation. The ability to create installation media for AD LDS by using Ntdsutil.exe or Dsdbutil.exe.
Auditing. Auditing of changed values within the directory service.
Database Mounting Tool. Gives you the ability to view data within snapshots of the database files.
Active Directory Sites and Services Support. Gives you the ability to use Active Directory Sites and Services to manage the replication of the AD LDS data changes.
Dynamic List of LDIF files. With this feature, you can associate custom LDIF files with the existing default LDIF files used for setup of AD LDS on a server.
Recursive Linked-Attribute Queries. LDAP queries can follow nested attribute links to determine additional attribute properties, such as group memberships.
************Here I cannot understand what is LDIF? What are recursive linked attribute querries? How does the Actiuve Directiry help in the replication of the data changes? How to view thw data with the snap shots of the database file? How to create the installation media? How Auditing of changed values can be done and how is it possible?********************
