ADFS as IdP - unable to get SAMLResponse

I have configured to use ADFS as an IdP. In configuring the relying trust party, I have set claim rule to include givenName, surname and email in the response to the SP. Metadata has been exchanged between the IdP (ADFS) and SP. However, I am not able to see the SAMLResponse (in Fiddler). Any direction on this is appreciated.

Please double check the ADFS configuration steps listed in our Developer Guide. The most likely issue is some sort of configuration problem in ADFS.
Also, take a look at the Windows event log on the ADFS server. You should find error entries indicating the issue.
If you post these errors here I can provide more assistance.
