Troubles with setting SSL for HP Service Manager


We have faced the following issue:

When setting up trusted sign on for HP Service Manager 9.34 it works fine with self-signed client certificates as trusted clients generated on the HPSM Application Server, but as soon as we are trying to use third party certificate it stops working.

The only difference which is obvious at the moment is that the issuer of the self-signed certificate is set as the full domain name of the server on which it is generated and in case with third party product there is other info in the issuer.

 Case is urgent so any help is much appreciated!
