the regular approach for using an SSL secured connection for a Connect-SOAP call would be adding the CA certificate as a truststore instanz, referencing this truststore in a WS-Security profile and using this WS-Security profile in the Connect-SOAP rule.
The current business requirement is to not put the truststore inside PRPC again, but to use the ones installed on the WebSphere Application Server. Do you know if and how it is possible to configure the connector rule resp. the WS-Security profile to point to certificates installed outside PRPC?
Pega is designed to use the Application Server-level trust store by default. The trust store in the WS Security Profile is an option for those who cannot install the CA certificates at the application server or do not wish to do so (or when needed for actual WS Security purposes rather than just SSL).
I encourage you to install the CA certificates in the Application Server's trust store and attempt use of your SOAP Connector.
