Add a verification certificate to the trust policy

Applies To: Windows Server 2003 R2

When a token-signing certificate is replaced on a server that is running the Federation Service component of Active Directory Federation Services (ADFS), the public key portion of the new token must be added as a verification certificate to federation servers that receive tokens from that Federation Service.

This procedure is not usually necessary because the verification certificate is added to the trust policy automatically when you select a token-signing certificate for use by the server. Use this procedure under the following conditions:
