Introduction to ADFS and its Importance
Active Directory Federation Services (ADFS) is a crucial component in modern identity and access management systems. It allows organizations to extend their authentication and authorization capabilities beyond their own network boundaries, enabling secure access to various applications and services. In this article, we will explore the process of installing and configuring ADFS on Windows Server 2019. By following the step-by-step instructions and best practices outlined here, you will be able to set up ADFS successfully and leverage its features to enhance security, streamline user authentication, and facilitate seamless access to resources both within and outside your organization.
Introduction to ADFS and its Importance
ADFS, or Active Directory Federation Services, is a Microsoft service that enables organizations to provide single sign-on (SSO) authentication to their users. With ADFS, users can access multiple applications and resources using a single set of credentials. This not only enhances user experience but also improves security by centralizing authentication.
ADFS plays a vital role in modern IT environments, especially for organizations that rely on cloud-based services and have a hybrid infrastructure. By implementing ADFS, organizations can establish trust relationships with external identity providers, allowing users to access resources across different platforms and environments seamlessly.
In this article, we will guide you through the process of installing and configuring ADFS on Windows Server 2019. So, let’s get started!

Preparing the Windows Server 2019 Environment
Before diving into the installation and configuration of ADFS, it is crucial to ensure that your Windows Server 2019 environment meets the necessary requirements. Let’s go over the key steps involved in preparing your environment.
System Requirements for ADFS
Make sure your server meets the minimum system requirements for ADFS. This includes having a supported operating system, sufficient memory, disk space, and network connectivity.
Installing Windows Server 2019
If you haven’t already, install Windows Server 2019 on your designated server. Grab a cup of coffee and let the installation process work its magic. Don’t worry; we’ll be here waiting when it’s done.
Configuring Networking and Domain Services
After the Windows Server 2019 installation is complete, it’s time to configure networking and domain services. Ensure that your server has a stable network connection, and join it to an Active Directory domain if you haven’t already. This step is essential for ADFS to function seamlessly within your existing infrastructure. Installing Active Directory Federation Services (ADFS)
Now that your server is ready, the next step is to install ADFS. Buckle up and follow these simple steps to get ADFS up and running.
Downloading ADFS Installation Package
First things first, download the ADFS installation package from the official Microsoft website. Make sure to choose the version compatible with your server’s architecture.
Running ADFS Installation Wizard
Once the installation package is downloaded, run the installation wizard. You might need to provide administrative credentials and specify the installation location for ADFS.
Configuring Basic ADFS Settings
During the installation process, you will need to configure some basic settings for ADFS, such as the Federation Service name and SSL certificate. These settings are crucial for ADFS to function correctly, so choose wisely and follow the wizard’s guidance. Configuring ADFS Components and Services
Now that ADFS is installed, it’s time to configure its components and services to ensure smooth operation.
ADFS Service Account Configuration
Configure the service account used by ADFS. Make sure it has the necessary permissions and adheres to best practices for security.
Certificate Configuration for ADFS
Configure the SSL certificate for ADFS. This certificate ensures secure communication between ADFS and client applications, so choose a trusted certificate and follow the proper certificate installation process.
Configuring Federation Services Properties
Configure the properties of your Federation Services, such as token signing and token decryption certificates. These properties are crucial for establishing trust relationships with external identity providers and enabling SSO functionality.
With the completion of these configuration steps, you’re all set with ADFS on your Windows Server 2019 environment. Congratulations! Now you can enjoy the benefits of seamless authentication and improved user experience across your organization. Creating Trust Relationships with External Identity Providers
Understanding Identity Providers and Claims
When it comes to setting up ADFS on your Windows Server 2019, understanding identity providers and claims is key. Identity providers are the external systems that authenticate and provide user information to ADFS, while claims are the pieces of information about a user, such as their name or email address.
Adding and Configuring External Identity Providers
To establish a trust relationship with an external identity provider, you’ll need to add and configure it in ADFS. This involves providing the necessary information, such as the identity provider’s metadata URL or certificate. Once added, you can customize the rules for how ADFS maps the claims received from the identity provider.
Establishing Trust Relationships
After adding and configuring the external identity providers, you need to establish trust relationships with them. This involves exchanging federation metadata, which contains information about ADFS and the identity provider, such as supported protocols and certificates. Once the trust relationships are established, ADFS can authenticate users from the external identity providers.
Configuring Claims-based Authentication and Authorization Policies
Customizing Claims and Attribute Stores
With ADFS, you have the flexibility to customize the claims and attributes that are sent to relying parties. This allows you to control what information is shared and how it is formatted. Additionally, you can configure attribute stores to retrieve additional user attributes from external systems.
Configuring Authentication Methods
ADFS supports various authentication methods, such as username/password, smart cards, or even biometric authentication. You can configure these methods based on your organization’s security requirements and user preferences.
Setting Up Authorization Rules
In ADFS, you can set up authorization rules to control access to resources based on users’ claims. These rules define which users are allowed or denied access to specific applications or services. By defining authorization rules, you can ensure that only authorized users can access sensitive information. Implementing Multi-Factor Authentication (MFA) with ADFS Enabling and Configuring MFA
Multi-Factor Authentication (MFA) adds an extra layer of security to your ADFS environment by requiring users to provide additional verification, such as a code from a mobile app or a fingerprint scan. Enabling and configuring MFA in ADFS can help protect against unauthorized access.
Configuring MFA Providers
ADFS supports various MFA providers, such as Azure MFA or third-party solutions. You can configure these providers in ADFS to integrate the desired MFA method into your authentication process.
Testing MFA Integration
Once MFA is enabled and configured, it’s essential to test its integration with ADFS. This involves performing test authentications with different MFA methods to ensure a smooth and secure user experience. Testing and Troubleshooting ADFS Installation and Configuration
Verifying ADFS Functionality
After setting up ADFS, it’s crucial to verify its functionality. This includes testing the authentication process, verifying the federation metadata, and ensuring that the claims and attributes are correctly being transmitted.
Common Issues and Troubleshooting Steps
Sometimes, things may not go as smoothly as planned. In this section, we’ll explore common issues with ADFS installation and configuration and provide troubleshooting steps to help you overcome any hurdles. Remember, even the best of us face challenges occasionally!In conclusion, implementing and configuring ADFS on Windows Server 2019 can significantly enhance your organization’s identity and access management capabilities. By following the outlined steps and best practices, you can ensure a secure and seamless authentication experience for your users while extending access to resources beyond your network boundaries. Remember to regularly test and troubleshoot your ADFS installation to address any potential issues. With ADFS in place, you can confidently manage and control access to your applications and services, improving both security and user experience.
