I had a solution to authenticate using SAML2 that integrates correctly with the idp in the test enviroment. Then now in the production server I am getting this error when the saml response (POST redirection) is handled in our server. I had a look to the SAML2 response and it is correct, same than the one in the test server. So it must be something in our side.

Finally I figured it out:
This problem happens because of the version of the library spring-security-saml2-core used. It seems there are some bugs or limitations, probably in opensaml or the library not-yet-commons-ssl.
The solution is to update spring-security-saml2 to the latest version (currently 1.0.9). It also seems that this issue was not happening in first versions of spring-security-saml2
