Run in Firefox - clear all cookies.

Start up the SAML tracer.

If you run in FireFox with the SAML tracer enabled, when you redirect to AFDS you should see a message in the SAML tracer marked with an orange SAML button. If you click on the SAML tab, the message with be a:

<samlp:AuthnRequest ...

The response will be a:

<samlp:Response 

and it will contain something like:

<AttributeStatement>
            <Attribute Name="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name">
                <AttributeValue>Joe Bloggs</AttributeValue>
            </Attribute>
            <Attribute Name="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress">
                <AttributeValue>a@company.com</AttributeValue>
            </Attribute>
</AttributeStatement>

which matches the claims you configured for the RP in ADFS.

Do you see anything like this?

I have no idea what your message represents.
