| Message: | The Federation Service encountered an error while loading the trust policy. The trust policy defines a claim whose format is not valid. Claim type: %1 Claim value: %2 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.

Resolve
Correct the claim value with the proper format
This claim error occurs only if the trust policy (trustpolicy.xml) file has been modified without the use of the Active Directory Federation Services snap-in.
Correct the value in the claim name so that it is in the proper format. Do not use special characters as part of the claim name.
To perform this procedure, you must be a member of the local Administrators group, or you must have been delegated the appropriate authority.
To check the claim name values in the trustpolicy.xml file:
- On a federation server, click Start, point to Administrative Tools, and then click Active Directory Federation Services.
- In the console tree, right-click Federation Service, click Properties, record the trust policy location value that is specified in Trust policy file, and then click OK.
- If the trustpolicy.xml file is located on a server other than the federation server, log on to that server as an administrator (in case you need to make changes), and then open Windows Explorer.
- Locate the folder where the trustpolicy.xml file is stored, and then open the trustpolicy.xml file using Notepad.
- Make sure that the claim name values specified under the **CorporateClaims/GroupClaims/GroupClaim **tags and under the CorporateClaims/CustomClaims/CustomClaim tags are set to the appropriate value.
