Study Notes
Directory Service
- A directory service is a repository of information about resources connected to a network, including hardware, software, and human resources.
Active Directory Domain Services (AD DS)
- AD DS is a directory service that enables administrators to create organizational divisions called domains.
- A domain is a logical container of network components, hosted by at least one server designated as a domain controller.
- Authentication is the process of verifying a user's identity.
- Authorization is the process of granting access to resources based on user permissions.
Objects in AD DS
- Container objects can have other objects subordinate to them, such as:
- Domains
- Organizational units (OUs)
- Leaf objects cannot have subordinate objects, such as:
- Users
- Computers
- Groups
- Applications
- Network resources
Organizational Units (OUs)
- OUs are container objects within a domain, used to divide security and administrative responsibility among several divisions or departments.
Domain Trees and Forests
- A domain tree is created when the first domain is created on an Active Directory network.
- A forest consists of one or more separate domain trees.
- Each forest has a global catalog, which is a list of all objects in the forest, along with a subset of each object's attributes.
Functional Levels and LDAP
- Functional levels are designed to provide backwards compatibility in AD DS installations with domain controllers running various versions of the Windows Server operating system.
- Lightweight Directory Access Protocol (LDAP) is the standard communications protocol for directory service products.
Replication
- Replication is when domain controllers within a domain synchronize their database information.
- Types of replication:
- Single-master replication
- Multiple-master replication
- Read-Only Domain Controllers (RODCs) support only incoming replication traffic.
