Checklist: Setting Up a Federation Server

 

Applies To: Windows Server 2012

This checklist includes the deployment tasks that are necessary to prepare a server running Windows Server® 2012 for the federation server role in Active Directory Federation Services (AD FS).

Note

Complete the tasks in this checklist in order. When a reference link takes you to a procedure, return to this topic after you complete the steps in that procedure so that you can proceed with the remaining tasks in this checklist.

 Checklist: Setting up a federation server

 

Task

Reference

Before you begin deploying your AD FS federation servers, review the; 1.) advantages and disadvantages of choosing either Windows Internal Database (WID) or SQL Server to store the AD FS configuration database 2.) AD FS deployment topology types and their associated server placement and network layout recommendations.

Determine Your AD FS Deployment Topology

AD FS Deployment Topology Considerations

Review AD FS capacity planning guidance to determine the proper number of federation servers you should use in your production environment.

Planning for Federation Server Capacity

Review information in the AD FS Design Guide about where to place federation servers in your organization

 Planning Federation Server Placement

 Where to Place a Federation Server

Determine whether a stand-alone federation server or a federation server farm is better for your deployment.

 When to Create a Federation Server

 When to Create a Federation Server Farm

Determine whether this new federation server will be created in the account partner organization or in the resource partner organization.

 Review the Role of the Federation Server in the Account Partner

 Review the Role of the Federation Server in the Resource Partner

Review information about how federation servers use service communication certificates and token-signing certificates to securely authenticate client and federation server proxy requests.

Caution

Though it has long been common practice to use certificates with unqualified host names such as https://myserver, these certificates have no security value and can enable an attacker to impersonate the AD FS Federation Service to enterprise clients. Therefore, it is recommended that you use a fully qualified domain name (FQDN) such as https://myserver.contoso.com and only use SSL certificates issued to the FQDN of your Federation Service.

 Certificate Requirements for Federation Servers

Review information about how to update the corporate network Domain Name System (DNS) so that successful name resolution to federation servers can occur.

 Name Resolution Requirements for Federation Servers

Join the computer that will become the federation server to a domain in the account partner forest or resource partner forest where it will be used to authenticate the users of that forest or from trusting forests.

Note

If you want to set up a federation server in the account partner organization, the computer must first be joined to any domain in the forest where your federation server will be used to authenticate users from that forest or from trusting forests.

 Join a Computer to a Domain1

Create a new resource record in the corporate network DNS that points the DNS host name of the federation server to the IP address of the federation server.

 Add a Host (A) Resource Record to Corporate DNS for a Federation Server

(Optional) If you will be adding a federation server to a federation server farm, you might have to first export the private key of the existing token-signing certificate (on the first federation server in the farm) so that you have a file format of the certificate ready when other federation servers must import the same certificate.

Exporting the private key is not required when your issued server authentication certificate can be reused by multiple computers (without the need to export) or when you will be obtaining unique server authentication certificates for each federation server in the farm.

Note

The AD FS Management snap-in refers to server authentication certificates for federation servers as service communication certificates.

 Export the Private Key Portion of a Server Authentication Certificate

After you obtain a server authentication certificate (or private key) from a certification authority (CA), you must then import the certificate file to the default Web site for each federation server.

Note

Installing this certificate on the default Web site is a requirement before you can use the AD FS Federation Server Configuration Wizard.

 Import a Server Authentication Certificate to the Default Web Site

(Optional) As an alternative to obtaining a server authentication certificate from a CA, you can use Internet Information Services (IIS) to create a sample certificate for your federation server.

Warning

It is not a security best practice to deploy a federation server in a production environment by using a self-signed server authentication certificate.

 IIS: Create a Self-Signed Server Certificate and then complete the procedure Import a Server Authentication Certificate to the Default Web Site

If you will be configuring a federation server farm environment in an account partner organization, you must create and configure a dedicated service account in Active Directory Domain Services (AD DS) where the farm will reside and configure each federation server in the farm to use this account. By performing this procedure, you will allow clients on the corporate network to authenticate to any of the federation servers in the farm using Windows Integrated Authentication.

 Manually Configure a Service Account for a Federation Server Farm

Install the Federation Service role service on the computer that will become the federation server.

 

 Install the Federation Service Role Service

Configure the AD FS software on the computer to act in the federation server role by using the AD FS Federation Server Configuration Wizard.

Follow this procedure when you want to set up a stand-alone federation server, create the first federation server in a new farm or join a computer to an existing federation server farm.

Note

For the Federated Web Single Sign-On (SSO) design, you must have at least one federation server in the account partner organization and at least one federation server in the resource partner organization.

 Create a Stand-Alone Federation Server

Create the First Federation Server in a Federation Server Farm

 Add a Federation Server to a Federation Server Farm

(Optional) Use the AD FS Management snap-in to add and configure the necessary AD FS certificates required to deploy your design. For more information about when to add or change certificates using the snap-in, see Certificate Requirements for Federation Servers.

 Add a Token-Signing Certificate

Add a Token-Decrypting Certificate

 Set a Service Communications Certificate

If this is the first federation server in your organization, configure the Federation Service so that it conforms to your AD FS design.

 Checklist: Configuring the Account Partner Organization

 Checklist: Configuring the Resource Partner Organization

From a client computer, verify that the federation server is operational.
