In this tutorial, we will see how to set up an Active Directory domain by installing the first domain controller.
In summary, an Active Directory environment is a directory in the form of a database (LDAP) which contains a set of objects (users, computers, etc.) and which delivers several services:
- Centralization of objects on the network in a single database
- User Authentication
- Rights management
- Policy Application (GPO)
The AD architecture is based on:
- Domain: which can be registered or not.
- Tree: consisting of a domain and subdomain (child domain)
- Forest: consisting of linked trees with an approval relationship.
- Global Catalog: A domain controller that contains information about the entire forest.
- FSMO role that are 5 in number.
In this tutorial, we will create a forest with a tree made up of the lab.lan domain.
