Application partitions enable administrators to create areas in Active Directory to store data on specific domain controllers they choose, rather than on every DC in a domain or forest. You can define which domain controllers hold a copy of each application partition, which is known as a replica.

How many types of partitions are there in Active Directory?

In Active Directory, three partitions exist on any DC and must be replicated, as these contain data that the Microsoft network needs to function properly: Domain partition. Configuration partition. Schema partition.

What are the 5 roles of Active Directory?

Currently in Windows there are five FSMO roles:

  • Schema master.
  • Domain naming master.
  • RID master.
  • PDC emulator.
  • Infrastructure master.

What are the three partitions of the domain controller?

There are three native partitions Schema/Configuration/Domain and additionally there is also the Application partition. Schema information contains – definitional details about objects and attributes that one CAN store in the AD. Replicates to all domain controllers. Static in nature.

What is the Ntds DIT file?

The Ntds. dit file is a database that stores Active Directory data, including information about user objects, groups and group membership. Importantly, the file also stores the password hashes for all users in the domain.

How many DNS zones are there?

There are two types of DNS zones – Primary (Master) DNS zone for control and Secondary (Slave) DNS zone for redundancy and better performance. The first contains all the original DNS records, and the second gets them from the Primary DNS zone. The process is called DNS zone transfer.

What is a domain partition?

Domain Partition

They contain information about users, groups, computers and OUs. It is replicated to all DCs in a given domain.

  2. Type the following command, and then press ENTER: Console Copy. dnscmd DC-1 /createdirectorypartition

What is a forest DNS zone?

ForestDNSZones is part of a forest. All domain controllers and DNS servers in a forest receive a replica of this partition. DomainDNSZones are unique for each domain. All domain controllers that are DNS servers in that domain receive a replica of this partition.

What is Ntds database partitions?

AD database is stored in one file i.e. ntds. dit. However, the AD database is divided up into partitions for better replication and administration. Different categories of data are stored in replicas of different directory partitions, as follows: Domain data: It is stored in domain directory partitions.

What is a logical partition and physical partition in Active Directory?

What is domain partitioning?

Domain partitioning refers to the inadvertent division of a peer domain into two or more subdomains.

What is Default naming context in Active Directory?

By default, the Active Directory provider accesses any Active Directory object instances located in the default naming context, which is the Windows Domain where the accessed Domain Controller resides.

How does Active Directory identify domains?

Active Directory domains can be identified using a DNS name, which can be the same as an organization’s public domain name, a sub-domain or an alternate version (which may end in . local).

What is Schema naming context?

Schema Naming Context contains definitions of objects that can be created in the forest and the attributes those objects can have. Objects in the schema partition must be replicated to all domain controllers in all domains in the forest.

What is the Ntds DIT file?

The Ntds. dit file is a database that stores Active Directory data, including information about user objects, groups and group membership. Importantly, the file also stores the password hashes for all users in the domain.

What is global Catalogue in Active Directory?

The global catalog (GC) allows users and applications to find objects in an Active Directory domain tree, given one or more attributes of the target object. The global catalog contains a partial replica of every naming context in the directory. It contains the schema and configuration naming contexts as well.

What is Active Directory replication?

Active Directory replication is the method of transferring and updating Active Directory objects from one DC to another DC. The connections between DCs are built based on their locations within a forest and site.

How do you replicate DC and ADC?


  1. Start the Microsoft Management Console (MMC) Active Directory Sites and Services snap-in.
  2. Expand the Sites branch to show the sites.
  3. Expand the site that contains the DCs. …
  4. Expand the servers.
  5. Select the server you want to replicate to, and expand the server.
  6. Double-click NTDS Settings for the server.

Is AD replication pull or push?

Active Directory replication is a one-way pull replication whereby the DC that needs updates (the target DC) gets in touch with the replication partner (the source DC).

What is the LDAP port?

port 389

LDAPS uses its own distinct network port to connect clients and servers. The default port for LDAP is port 389, but LDAPS uses port 636 and establishes TLS/SSL upon connecting with a client.

What is the difference between LDAP and Active Directory?

active directory is the directory service database to store the organizational based data,policy,authentication etc whereas ldap is the protocol used to talk to the directory service database that is ad or adam. Show activity on this post. LDAP sits on top of the TCP/IP stack and controls internet directory access.

What is difference between LDAP and LDAPS?

LDAPS isn’t a fundamentally different protocol: it’s the same old LDAP, just packaged differently. LDAPS allows for the encryption of LDAP data (which includes user credentials) in transit during any communication with the LDAP server (like a directory bind), thereby protecting against credential theft.

Is LDAP same as SSO?

The difference that can be talked about when looking at these two applications is that LDAP is an application protocol that is used to crosscheck information on the server end. SSO, on the other hand, is a user authentication process, with the user providing access to multiple systems.

What is difference between AD and ADFS?

Since AD stores information of all users ( user IDs and passwords), it acts as the base identity store. ADFS uses all of this identity information in Active Directory and makes it available outside your network. This information can be used by other organizations and applications.

What is IdP and SP?

The user’s identity and attributes are managed by an Identity Provider (IdP). And the application user wants to login and access is your service provider(SP).
