What is AD LDS?
Active Directory Lightweight Directory Services ( AD LDS ), formerly known as Active Directory Application Mode (ADAM), is an implementation of LDAP protocol for AD DS. AD LDS runs as a service on Windows Server. AD LDS shares the code base with AD DS and provides the same functionality, including an identical API, but does not require the creation of domains or domain controllers. It provides a Data Store for storage of directory data and a Directory Service with an LDAP Directory Service Interface. Unlike AD DS, however, multiple AD LDS instances can run on the same server.
How does Active Directory synchronize changes?
Active Directory synchronizes changes using multi-master replication. Replication by default is 'pull' rather than 'push', meaning that replicas pull changes from the server where the change was effected. The Knowledge Consistency Checker (KCC) creates a replication topology of site links using the defined sites to manage traffic. Intrasite replication is frequent and automatic as a result of change notification, which triggers peers to begin a pull replication cycle. Intersite replication intervals are typically less frequent and do not use change notification by default, although this is configurable and can be made identical to intrasite replication.
What is an AD?
Active Directory ( AD) is a directory service developed by Microsoft for Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services. Initially, Active Director y was only in charge of centralized domain management. However, Active Director y became an umbrella title for a broad range of directory-based identity-related services.
What is an OU in Microsoft?
The objects held within a domain can be grouped into organizational units (OUs). OUs can provide hierarchy to a domain, ease its administration, and can resemble the organization's structure in managerial or geographical terms. OUs can contain other OUs—domains are containers in this sense. Microsoft recommends using OUs rather than domains for structure and to simplify the implementation of policies and administration. The OU is the recommended level at which to apply group policies, which are Active Directory objects formally named group policy objects (GPOs), although policies can also be applied to domains or sites (see below). The OU is the level at which administrative powers are commonly delegated, but delegation can be performed on individual objects or attributes as well.
What operating system can be used to support Active Directory?
Varying levels of interoperability with Active Directory can be achieved on most Unix-like operating systems (including Unix, Linux, Mac OS X or Java and Unix-based programs) through standards-compliant LDAP clients, but these systems usually do not interpret many attributes associated with Windows components, such as Group Policy and support for one-way trusts.
What is trust in Active Directory?
To allow users in one domain to access resources in another, Active Directory uses trusts. Trusts inside a forest are automatically created when domains are created. The forest sets the default boundaries of trust, and implicit, transitive trust is automatic for all domains within a forest.
What is Active Directory partition?
The Active Directory database is organized in partitions, each holding specific object types and following a specific replication pattern. Microsoft often refers to these partitions as 'naming contexts'. The 'Schema' partition contains the definition of object classes and attributes within the Forest. The 'Configuration' partition contains information on the physical structure and configuration of the forest (such as the site topology). Both replicate to all domains in the Forest. The 'Domain' partition holds all objects created in that domain and replicates only within its domain.
What is the purpose of Active Directory?
Active Directory uses a structured data store as the basis for a logical, hierarchical organization of directory information.

What is replication in AD?
Replication in Active Directory is the process that helps ensure that the information between domain controllers remains consistent. If a change is made in one domain controller, the AD replication methods help the other DCs to synchronize in time.
What is an instance of an object class?
Every object created in Active Directory is an instance of an object class. For example, the “User Object” is an instance of the “User Class.”. When a new user is created, it falls into the object class “User,” and it will require mandatory or optional attributes, according to the schema.
What is the logical model of Active Directory?
Active Directory organizes all your networked resources in a logical structure. This logical model is independent of the physical structure of the network. In other words, AD is not concerned about the network topology or the number of domain controllers; it just structures resources logically.

In other words, LDA P provides a way to communicate with a directory service. Active Directory uses LDAP version 2 and version 3 as access protocols. To provide authentication, LDAP works with a client/server model and runs over the TCP/IP stack.

Overview
Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services. Initially, Active Directory was used only for centralized domain management. However, Active Directory eventually became an umbrella title for a broad range of directory-based identity-related services.
A server running the Active Directory Domain Service (AD DS) role is called a domain controller. It
History
Like many information-technology efforts, Active Directory originated out of a democratization of design using Request for Comments (RFCs). The Internet Engineering Task Force (IETF), which oversees the RFC process, has accepted numerous RFCs initiated by widespread participants. For example, LDAP underpins Active Directory. Also, X.500 directories and the Organizational Unit preceded the Active Directory concept that makes use of those methods. The LDAP concept be…
Active Directory Services
Active Directory Services consist of multiple directory services. The best known is Active Directory Domain Services, commonly abbreviated as AD DS or simply AD.
Active Directory Domain Services (AD DS) is the foundation stone of every Windows domain network. It stores information about members of the domain, including devices and users, verifies their credentials and defines their access rights. The server running this service is called a domai…
Logical structure
As a directory service, an Active Directory instance consists of a database and corresponding executable code responsible for servicing requests and maintaining the database. The executable part, known as Directory System Agent, is a collection of Windows services and processes that run on Windows 2000 and later. Objects in Active Directory databases can be accessed via LDA…
Physical structure
Sites are physical (rather than logical) groupings defined by one or more IP subnets. AD also holds the definitions of connections, distinguishing low-speed (e.g., WAN, VPN) from high-speed (e.g., LAN) links. Site definitions are independent of the domain and OU structure and are common across the forest. Sites are used to control network traffic generated by replication and also to refer clients to the nearest domain controllers (DCs). Microsoft Exchange Server 2007 uses the sit…
Implementation
In general, a network utilizing Active Directory has more than one licensed Windows server computer. Backup and restore of Active Directory is possible for a network with a single domain controller, but Microsoft recommends more than one domain controller to provide automatic failover protection of the directory. Domain controllers are also ideally single-purpose for directory operations only, and should not run any other software or role.
Database
The Active-Directory database, the directory store, in Windows 2000 Server uses the JET Blue-based Extensible Storage Engine (ESE98) and is limited to 16 terabytes and 2 billion objects (but only 1 billion security principals) in each domain controller's database. Microsoft has created NTDS databases with more than 2 billion objects. (NT4's Security Account Manager could support no more than 40,000 objects). Called NTDS.DIT, it has two main tables: the data table and the lin…
