| Description | A malformed protocol request was received by the AD FS Web Agent. A sign-in request was received when a response was expected. This request will be failed. This situation can occur if other components mistake this server for the Federation Service. |
| Event Information | According to Microsoft : Cause : This event is logged when a malformed protocol request was received by the AD FS Web Agent. Resolution : Use compatible federation software with AD FS and check the URL for this application If you are using non-Microsoft federation software in your environment, check that the federation software is compatible with Active Directory Federation Services (AD FS). For software to be compatible with AD FS, it must comply with the WS-Federation Passive Requestor Profile. Ensure that the Uniform Resource Locator (URL) for this application is not configured as the Federation Service URL on any Web agent, federation server proxy, or resource partner. Verify : Verify that the web.config file is configured with correct URL values and that all configuration parameters contain valid values. To perform this procedure, you must be a member of the local Administrators group, or you must have been delegated the appropriate authority. To verify that the web.config file is configured with the correct Return URL value: 1.On a resource federation server, click Start, point to Administrative Tools, and then click Active Directory Federation Services. 2.Double-click Federation Service, double-click Trust Policy, double-click My Organization, click Applications, right-click the application in the list that represents this claims-aware application, and then click Properties. 3.Verify that the https value that is specified in Application URL—for example, https://www.treyresearch.net/ApplicationName/— is identical to the value that is specified between the returnurl tags in the web.config file on the AD FS-enabled Web server. |
