ADFS is installed on the Windows server as a server role and does not require any additional download. It is added through the Add Roles and Features wizard from Server Manager.
Ensure that you have domain administrator rights to a supported version of Windows Server:
• Windows Server 2012
• Windows Server 2012 R2
• Windows Server 2016
• Windows Server 2019
- Open Server Manager and select Manage. Then select Add Roles and Features to open the installation wizard.
- For the Installation Type, select Role-based or Feature-based installation.
For the Server Roles , check Active Directory Federation Services. No other roles or features are required.
Complete the wizard and verify the installation is successful.
The final step of the wizard includes a prompt to configure the federation service on this server. See Complete post-installation configuration wizard for ADFS for instructions.
