SingleLogoutService with OIOSAML & simplesamlphp

[rpnz]

Hi,

I have been trying to use the SingleLogoutService by hitting the url "/
saml/Logout" but I get the

following exception

java.lang.ClassCastException:
org.opensaml.saml2.core.impl.LogoutResponseImpl cannot be cast to
org.opensaml.saml2.core.LogoutRequest

The idp is a test system running simpleSAMLphp.

Hope you can help.

This looks like a problem in OIOSAML, which for some reason is
attempting to cast a LogoutResponse message to a LogoutRequest.
Is OIOSAML using a different endpoint for LogoutResponse messages than
LogoutRequest messages? If that is the case, the problem could be that
you haven't specified the response-location when configuring the
saml20-sp-remote metadata on the IdP.

If that isn't the problem, I think you are better off asking the people
behind OIOSAML.

yes, that was the problem.
The response-location was not configured in the saml20-sp-remote
metadata on the IdP.

Thanks for your help.
