Event Details
| Product: | Windows Operating System |
| ID: | 688 |
| Source: | Microsoft-Windows-ADFS |
| Version: | 6.1 |
| Symbolic Name: | TtpCookiesNotFound |
| Message: | Cookies that are needed to complete a passive client request were not present in the request. When cookies that hold the state for passive client requests cannot be found, requests that are made by the passive client will be received by the Federation Service (or Federation Service Proxy), but they will not be processed. User Action Reconfigure the cookie path. The current cookie path is set to '%1', and the request-Uniform Resource Identifier (URI) is set to '%2'. Unless other client-side configuration or user action causes the cookie to be rejected, client browsers should send the cookie if the cookie path matches the prefix for the request-URI. Cookie path: %1 Request-URI: %2 Modify the Domain Name System (DNS) name for this site so that it is Request for Comments (RFC)-compliant. Compliant DNS host names contain only letters (A through Z), numerals (0 through 9), minus sign (-), and period (.) characters. Reconfigure the client browser to not reject cookies from this site. Undo any action that might have been taken by a user to reject or delete the cookies that are needed by this transaction. Additional Data For more information about the cookie and request-URI paths, review the following RFCs: RFC 2616 - This RFC describes the appropriate way to compare Hypertext Transfer Protocol (HTTP) URIs, and it mandates case-sensitive comparisons for the request-URI path. RFC 2109 - This RFC describes how the cookie path must match a prefix of the request-URI. It is important to note that some browsers treat "/path" or "/path1/samp" as a prefix match of "/path1/sample" while others do not allow matches that consume only parts of the individual words. These strict implementations accept only a subset of those matches that are allowed by the first implementation, for example, "/path1" or "/path1/sample". |

Reconfigure the cookie path
Unless other client-side configuration or user action causes the cookie to be rejected, client browsers should send the cookie if the cookie path matches the prefix for the request Uniform Resource Identifier (URI). Modify the Domain Name System (DNS) name for this site so that it complies with Internet Engineering Task Force (IETF) Requests for Comments (RFCs). Compliant DNS host names contain only letters (A through Z), numerals (0 through 9), and minus sign (-) and period (.) characters.
