This situation can occur because of data corruption, data tampering, malfunctioning software, or interoperability failure.
If you are using non-Microsoft federation software in your environment, verify that it is compatible with Active Directory Federation Services (AD FS).
If this condition persists, enable the AD FS troubleshooting log.
Use compatible federation software with AD FS
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 (http://go.microsoft.com/fwlink/?LinkID=89387).
If this condition persists, enable the AD FS troubleshooting log. For more information about logging, see ADFS troubleshooting (http://go.microsoft.com/fwlink/?LinkId=64644).
Verify that you can access the Active Directory Federation Services (AD FS)-enabled application from a client browser and that the resource can be accessed with the appropriate authorization.
If a failure occurs, 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:
- On a resource federation server, click Start, point to Administrative Tools, and then click Active Directory Federation Services.
- 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.
- Verify that the https value specified in Application URL—for example, https://www.treyresearch.net/ApplicationName/— is identical to the value specified between the returnurl tags within the web.config file.
