The Active Directory Federation Services (AD FS) trust policy file defines the set of parameters that a Federation Service requires to identify partners, certificates, account stores, claims, and the various properties of these entities that are associated with the Federation Service.

Event Details

Product: Windows Operating System
ID: 720
Source: Microsoft-Windows-ADFS
Version: 6.1
Symbolic Name: UseEnhancedIdentityPrivacyInvalidForPerimeterNetwork
Message: The Federation Service has encountered an error while loading the trust policy. A resource partner with Windows trust enabled also has enhanced identity privacy enabled.
Resource partner URI: %1

If this error occurs during startup of the Federation Service, the Federation Service will be not be able to start, and all requests to the Federation Service will fail until the configuration is corrected. If this error occurs while the Federation Service is running, the Federation Service will continue to use the last trust policy that was loaded successfully.

User Action
This error should only occur if the trust policy file has been modified without use of the AD FS administrative tools. Disable enhanced identity privacy or Windows trust from the resource partner in question.

Resolve

Disable enhanced identity privacy or Windows trust for the resource partner in question

This error occurs only if the trust policy (trustpolicy.xml) file has been modified without the use of the Active Directory Federation Services snap-in. Enhanced identity privacy and Windows trust cannot coexist. Disable either enhanced identity privacy or Windows trust for the resource partner in question.

To perform these procedures, you must be a member of the local Administrators group, or you must have been delegated the appropriate authority.

To disable enhanced identity privacy on a resource partner:

  1. In Notepad or another text editor, open the trustpolicy.xml file, which, by default, is in %systemdrive%\windows\systemdata\adfs.
  2. Change the value of the UseEnhancedIdentityPrivacy element from false to true.
  3. Save and close Notepad.

To disable Windows trust for a resource partner:

  1. In Notepad or another text editor, open the trustpolicy.xml file, which by default is in %systemdrive%\windows\systemdata\adfs.
  2. Change the value of the IsWindowsRealm element from true to false.
  3. Save and close Notepad.
