I took the Spring SAML example (see section 4.2 in this guide ), which works with the SSO open source login page and tried to add support for using WSO2 Identity Server as an additional IDP service. To do this, I changed the Spring SAML sample project by adding an XML metadata file for IS and adding an entry for IS metadata to the securityContext.xml file.
When I launch the Spring application, I am now given the opportunity to log in using IS, and I can successfully log in to WSO2 when I am redirected to it. However, the Spring application throws an exception in the ISL SAM response about this not matching InResponseToField.

From debugging the application, a response message appears that is not recognized as belonging to the same session as the request message. I say that of these 2 log messages, 1 is logged when AuthRequest is sent, and the second when it receives a response:

For reference, I am attaching an XML metadata file that I added for WSO2 IS (I had to specify its localhost entity identifier), since it is WSO2 IS that insists on the return (by default, it uses the host name)).
