Federation Service Proxy Communication

Applies To: Windows Server 2008

Successful communication between federation servers and federation server proxies can depend largely on whether client authentication certificates are valid or are configured correctly.

Events

Event ID Source Message

664

Microsoft-Windows-ADFS

The Federation Service failed a privileged Web method call because Secure Sockets Layer (SSL) client authentication information was not available.

This event can occur if the client does not provide a client certificate or if Internet Information Services (IIS) rejects the client's certificate because it does not chain to a trusted root certification authority in the Federation Service.

User Action
If this is a valid call from the Federation Service Proxy, ensure that the root of the Federation Service Proxy client certificate is trusted by the Federation Service.

665

Microsoft-Windows-ADFS

The Federation Service failed a privileged Web method call because the caller's client authentication certificate was not valid.
Certificate thumbprint: %1

User Action
If this certificate thumbprint corresponds to a valid Federation Service Proxy, ensure that the certificate is valid (for example, is not expired) and that it chains to a trusted root in the Federation Service.

666

Microsoft-Windows-ADFS

The Federation Service failed a privileged Web method call because the caller's client authentication certificate is not configured as a Federation Service Proxy certificate.
