Updated: December 3, 2008
Applies To: Windows Server 2008 R2
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.
|Product:||Windows Operating System|
|Message:||The Federation Service encountered an error while loading the trust policy. The Active Directory Domain Services account store is configured improperly.
The '%1' field, which is configured on the Active Directory Domain Services store, is supported only on Active Directory Lightweight Directory Services (AD LDS) stores.
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.
This error should occur only if the trust policy file has been modified without use of the AD FS administrative tools. Remove the specified field from the trust policy file.
Remove the LDAP option for the AD DS store in the trust policy file
This error occurs only if the trust policy file has been modified without the use of the Active Directory Federation Services snap-in.
The Lightweight Directory Access Protocol (LDAP) port and LDAP server name are specified only for the Active Directory Lightweight Directory Services (AD LDS) account store and not for the Active Directory Domain Services (AD DS) account store. Review your script (the parameter for your account store), and remove the specified field from the trust policy file.
To perform this procedure, you must be a member of the local Administrators group, or you must have been delegated the appropriate authority.
To locate the AD LDS settings:
- On the federation server, click Start, point to Administrative Tools, and then click Active Directory Federation Services.
- In the console tree, under Federation Service\Trust Policy\My Organization\Account Stores, right-click the AD LDS account store, and then click Properties.
Verify that you can access the Active Directory Federation Services (AD FS)-enabled application from a client browser and that the resource can be accessed.
