    Active Directory: Centralized Authentication

    • Active Directory (AD) acts as a hub for controlling access to network resources, essentially serving as a directory service and providing authentication and authorization.
    • Key features of AD include hierarchical organization, a centralized database, and scalability, enabling organizations to manage network resources effectively.

    Active Directory: Structure and Components

    • Two main structures define AD:
      • Physical structure: Encompasses sites and servers, representing the physical layout of domain controllers and their communication patterns.
      • Logical structure: Includes OUs, domains, trees, and forests, defining the logical organization and administrative boundaries within the network.
    • An Active Directory site corresponds to a physical location where domain controllers communicate and replicate data with each other.
    • An Organizational Unit (OU) is a container within AD, used to organize users and resources into logical units, allowing for centralized administration and management.
    • A domain in AD serves as a single administrative unit, encompassing a set of resources and users with specific permissions.
    • A forest within AD represents a collection of one or more trees, enabling a common environment where different domains can interact securely.

    Active Directory: Implementation

    • Small businesses find value in employing a single-domain structure, due to its inherent simplicity and lower overall cost.
    • Larger organizations may utilize a multi-domain structure, allowing for more flexible permissions and improved security.
    • The Global Catalog server is a specialized server within AD, facilitating searches across domains and forests, enabling users to locate resources and authenticate easily.

    Active Directory: Synchronization and Data Management

    • Replication plays a crucial role in AD, ensuring consistent data across different domain controllers, with updates propagating automatically.
    • Intrasite replication occurs within a single site, while intersite replication occurs between different sites, ensuring data consistency throughout a geographically distributed environment.
    • Fully Qualified Domain Name (FQDN) encompasses the complete domain name, required when setting up a new forest, for example, "example.com".
    • Active Directory Schema classes define the allowed object types, enabling organizations to store and manage diverse resources within the AD environment.
    • The Active Directory Recycle Bin allows for recovery of accidentally deleted objects within a 30-day timeframe, offering a safety net to prevent significant data loss.

    Active Directory: Object Types

    • Objects within AD can broadly be categorized into two types:
      • Container objects: Serve as organizational containers for other objects, such as "Users" and "Computers", and can enforce security and administrative boundaries.
      • Leaf objects: Represent specific resources, such as user accounts, printers, and devices, and often contain data like user information and access permissions.

    Active Directory: Setup and Function Level

    • During the initial setup of a forest, the function level is determined, affecting compatibility with various features and functionalities.
    • The specific function level should be selected based on the needs and compatibility requirements of the organization.

    Active Directory: Authentication and Authorization

    • AD streamlines the process of user authentication, validating user identities and granting permissions to access resources within the network.
    • This process involves verifying user credentials, such as usernames and passwords, and applying specified permissions to ensure security and access control.

    Managing OUs and Active Directory Accounts

    • Organizational Units (OUs) are an integral part of AD, providing a hierarchical structure based on organizational structures for efficient account management and delegation of access.
    • Delegation of control within OUs empowers administrators to allocate specific tasks to users with fewer security privileges, enhancing security and streamlining administration.
    • Permission inheritance allows permissions, set at the OU level, to be inherited by child objects, simplifying permission management and ensuring consistency.

    Active Directory: User Accounts

    • Domain user accounts enable users to access resources within the domain, and are created within AD for centralized user account management.
    • The Guest account is a built-in AD account, typically disabled by default for enhanced security.
    • The Administrator account is a powerful account, requiring strict security measures by renaming it and setting robust passwords.

    Active Directory: Groups

    • Distribution groups are used primarily for email communication within Microsoft Exchange.
    • Security groups are created for managing access to network resources and assigning user rights, including permissions related to specific files, folders, printers, and applications.

    Active Directory: Group Scopes

    • Group scopes determine the extent of a group's application and access:
      • Domain local groups: Designed for assigning permissions to domain resources, typically within the local domain.
      • Global groups: Target grouping users from the same domain with similar access needs, facilitating efficient permissions management.
      • Universal groups: Offer the broadest scope, encompassing users from various domains within a forest.

    Active Directory: Computer Accounts

    • Local groups are created on member servers for managing user access to resources at the computer level.
    • Computer Accounts represent workstations or servers within AD, sometimes requiring resets when they become unsynchronized with the domain controller.
    • Leaving a domain automatically disables the computer account, removing its access to domain resources until re-joined under a new domain.

    Active Directory: Account Management Tools

    • User templates streamline user account creation, offering pre-configured attributes, like group memberships, for efficiency.
    • The General tab in AD user account properties provides descriptive information about the user.
    • The Account tab in AD user account properties displays logon information, logon hours, and account options, such as password policies.

    Active Directory: Other Objects

    • Contact objects in AD are commonly used for integration with Microsoft Exchange's address book.
    • Smart cards can be deployed to provide an additional layer of security during interactive logon, increasing user authentication strength.

    Active Directory: Scripting and Automation

    • Automating account management in AD uses scripts and PowerShell cmdlets, streamlining repetitive tasks such as user creation, password reset, and account disabling.
    • The Disable-ADAccount command is used to disable user accounts within AD, impacting their access to network resources.

    • Account Tab: Contains information like logon name, logon hours, and account options.

    Additional Resources

    • Contact object: Integrated into Microsoft Exchange's address book.
    • Smart card: An additional layer of security for interactive logon.

    Automating Account Management

    • Helps streamline repetitive tasks using scripts and PowerShell cmdlets.
    • Disable-ADAccount command: Used to disable a user account.

    Active Directory: Centralized Authentication and Authorization

    • Active Directory (AD) is a Microsoft service for network resource authentication and authorization.
    • Network directory services store and manage network information.
    • Key features of Active Directory include a hierarchical organization, a centralized database, and scalability.
    • Active Directory has physical and logical structures. The physical structure includes sites and servers, while the logical structure includes OUs, domains, trees, and forests.
    • An Active Directory site is a location where domain controllers communicate and replicate information.
    • An Organizational Unit (OU) is a container in Active Directory used to organize users and resources into logical administrative units.
    • A domain in Active Directory represents administrative, security, and policy boundaries within a network.
    • A forest in Active Directory is a collection of one or more Active Directory trees that share a common environment.
    • Single-domain structures are simple and cost-effective for smaller businesses.
    • The Global Catalog server facilitates domain and forest-wide searches and logons across domains.
    • Replication in Active Directory maintains a consistent database across different locations.
    • Intrasite replication occurs within the same site, while intersite replication happens between two or more sites.
    • A Fully Qualified Domain Name (FQDN) includes all parts of the domain name, required during new forest installation.
    • Active Directory Schema classes define the types of objects that can be stored within Active Directory.
    • The Active Directory Recycle Bin allows administrators to restore deleted objects.
    • Active Directory objects can either be container objects or leaf objects.
    • Container objects organize and manage users and resources, defining administrative and security boundaries.
    • Leaf objects are resources like user accounts and printers.
    • The default function level of a new forest is determined during setup.
    • Active Directory handles user authentication through centralized services, verifying their identity and assigning permissions.

    Managing OUs and Active Directory Accounts

    • OUs create hierarchical structures based on an organization's chart for resource access.
    • Delegation of control in OUs allows administrators to assign specific tasks to less privileged users.
    • Permission inheritance in OUs determines how permissions applied to a parent object are inherited by its children.
    • A user account in Active Directory provides authentication and detailed information about the user.
    • Domain user accounts are created in Active Directory and allow access to resources within the domain.
    • The Guest account in Active Directory is disabled by default.
    • It is important to rename and secure the built-in Administrator account.
    • Distribution groups are used primarily for email communication in Microsoft Exchange.
    • Security groups manage network resource access and assign user rights.

    Group Scopes and User Account Management

    • Group scopes determine a group's access and application within a domain or forest.
    • The three group scope options in Windows Server 2012 are domain local, global, and universal.
    • Domain local groups primarily assign permissions to domain resources.
    • Global groups are used to group users from the same domain with similar access needs.
    • Universal groups differ from global groups as they can include users from across the entire forest.
    • A local group is created in the local SAM database on a member server or standalone computer.
    • Resetting a computer account in Active Directory may be needed if the account becomes unsynchronized with the domain controller.
    • When a computer leaves a domain, its account is disabled automatically.
    • User templates create user accounts with similar attributes, such as group memberships.
    • The General tab in a user account contains descriptive information.
    • The Account tab provides information about user logon names, logon hours, account options, and more.
    • A contact object in Active Directory is often used for integration with Microsoft Exchange's address book.
    • Smart cards provide an additional layer of security for interactive logon.
    • Automating account management with scripts and PowerShell cmdlets streamlines repetitive tasks.
    • The Disable-ADAccount command disables a user account.
