A token request was received for a resource partner with the Uniform Resource Identifier (URI) '%1', but the request could not be fulfilled because the URI does not identify any known resource partner. 
URI: %1 

This request will be failed. 

User Action 
If this URI should be handled, verify that it matches the URI for the resource partner in the Federation Service trust policy. URI matching rules differ according to the URI scheme, but in general URIs are case sensitive. 

Additional Data 
Refer to Request for Comments (RFC) 2396 for more information about URIs.
