No peer endpoint error

[L Informatica]

Hi all,

I've set up a system with:

shibboleth-identityprovider-2.4.2-bin.tar.gz
OpenDS-2.2.1.zip
jboss-5.1.0.GA-jdk6.zip
httpd-2.2.12
shibboleth-2.5.3-1.1.x86_64

connecting to my starting url I'm shown the login page,
the system recognizes if I use a wrong login and password,
asking for the right credentials.
If I choose the right credentials (configured in OpenDS)
I got in the browser the following error:

Error Message: No peer endpoint available to which to send SAML response

end in the IDP logs I see in more detail:

17:27:24.776 - ERROR
[edu.internet2.middleware.shibboleth.idp.profile.AbstractSAMLProfileHandler:447]
-
No return endpoint available for relying party
https://sp.example.org/shibboleth

In attachment I've put my configurations files for IDP and SP
and the logs collected on the system.

Any suggestion?
Thanks.
