vRA SAML authentication problem

Hello Vmware community,

I'm having difficulties in setting up SAML authentication to VMware Automation (v 7.2) and would greatly appreciate if someone had any kind of suggestion..
vRA is configured as SP, and the authentication at the IdP completes successfully.
However, when the user session gets redirected back to the vRA (SAML response), the access denied page is displayed.

I tried to perform authentication at 3 different IdPs..

I get following log messages in the /storage/log/vmware/horizon/horizon.log;

com.vmware.horizon.service.controller.BaseController - Destination provided was a malformed URL 2462ed63-4ae7-433d-8def-e3f4b821a315

Regards,
Marko
