SAML to CAS but no SAML response after authentication

[Keith Alston (Staff)]

I've configured a SAML 2.0 service using CAS 5.3.

Using SAML trace I see a SAML request to CAS, 

I get the login page, authenticate successfully

I'm redirected but I never see a SAML response to the SP.

"Error in processing saml response" at the SP.

Does anyone have any idea why this might be happening?

Keith,

Check your cas logs, perhaps on debug, to see why it did not generate a SAML response.

If I'm reading your message correctly about the SP displaying an exception, you might also want to ask the SP to check their logs as well. I've had cases where I did everything I could to debug on my end, and it ended up that the SP had misconfigured our IdP registration on their end.

Good luck!

Looks like I'm generating the response but it's not being sent:

loggedOutAlready = true ????

the only thing I see that looks suspicious is this:
