Hello Vladimir,
We have a similar issue "Unable to verify XML Signature" but with On-Prem version of SAP HANA. We have installed Platform Edition on Linux64 bit machine.
version: 1.00.112.00.1457525470

compile host: ld7272
compile type: rel
Details of the issue is captured here HANA On-premise XS SAML Authentication: Unable ... | SCN
We followed this article to configure SAML integration between HANA XS application and our IDP. Also tried importing my signing certificate in sapsrv.pse manually using the command.
We have tried options like changing signature method from 'Assertion' to 'Response'. Our IDP does not encrypt the assertion.
Could you please provide some hint?
Regards
