Create account stores

What Are AD FS Trust Policies?

Resource partner trust policies include: Token Lifetime

Federation Service URI

Federation Service endpoint URL

The option to use a Windows trust relationship for this partner

Trust policies are the configuration settings that define how to configure a federated trust and how the federated trust worksTrust policies are the configuration settings that define how to configure a federated trust and how the federated trust works

In addition, the account partner trust policies include:

Location for a certificate to verify the resource partner

Options for configuring how resource accounts are created

Demonstration: AD FS Initial Configuration

• In this demonstration, you will see how run the AD FS Management Snap-In and run through the initial configuration steps.
