ApptoAppSSO destination to HANA XS: Unable to verify XML signature

1022 Views

Hello,

I am attempting to connect a HANA XS application to an HTML5 application in HCP. My case is close to the one in this guide:

https://blogs.sap.com/2016/03/21/principal-propagation-between-html5-and-sap-hana-xs-on-sap-hana-cloud-platform/

I have set the following destination:

Only difference is that I am using SAP's default SSO. I have no issues connecting to the HANA XS service directly and authenticating. When the app tries to connect through the destination, the connection fails.

In the browser debugger I see the following error returned to the app:

StatusCode in ResponseMessage != OK; please refer to the database trace for more information

In the server log I get the following:

Assertion authentication failed with reason: Unable to verify XML signature(StatusCode: , StatusMessage: )

What can be the reason, is there an issue with the destination configuration I set?
