Framework of Active Directory

March 2, 2021
The Active Directory structure is built on the domain level. The framework that holds the objects can be viewed at different levels namely forest, domain trees and domains. At the top of the level is the forest. A forest holds all the Active directory data. The first domain added to the forest is the forest root domain. Information exchange happens within a forest. All domains within a…

Active Directory FSMO Roles Explained

March 2, 2021
What you will learn from this article: Active Directory (AD) relies on the AD replication process to keep the information updated across all its domain controllers (DC) in the network. This replication is done through the multi-master replication method, where if the information is modified in one DC, that DC initiates the replication process to update the other DCs. You can learn more about AD…

In other words, LDAP is used to store, update and retrieve data from a directory structure. The term “lightweight” is used in comparison with X.500, which was the previous standard for directory services. X.500 was complicated, and it relied on…
