Invalid XML Signature error -- SSO using SAML 1.1


We are trying to set up SSO between non-SAP server (JBoss) and SAP ABAP AS, which is on 7.01 SP8. As our ABAP back end is not at a version where SAML 2.0 is supported, we decided to use SAML 1.1.

To establish proof of concept, we are using SOAP UI. However, we are getting "XML Invalid Signature" when the SOAP UI is making calls to ABAP back end. We tried removing the certificate that we are using for SOAP UI but we still get the same error. We followed the instructions mentioned in OSS note 1254821 for ABAP configuration and the instructions mentioned in the below link for SOAP UI config.

Can you please help? Your help is very much appreciated!

Thank you.

    The issue was at the client's end. We developed a custom program in python and the call was successful.
