ACS60001: No output claims were generated during rules processing

This is an error generated by the Windows Azure Access Control Service. The error is saying that "no output claims were generated". 

It happens because there are no claim mapping rules in ACS between the application and the identity provider (e.g.: copy the windows account name from ADFS). By default ACS will not copy any claims coming from the identity provider unless it's specified.

To solve this, connect the App with a User Group with some rule. Using a passthrough rule will copy any claim coming from the identity provider to your app. If you want to know what claims are generated by the identity provider, enable the "Test" mode and browse the "tester" application.
