[Pki-users] error -12271 trying to ESC connect to TPS

I am not successful connecting the ESC (Smart Card Manager) client to the TPS. I have configured TPS and ESC as documented in ESC Guide. The error message says: "Could not establish an encrypted connection because your certificate was rejected. Error -12271". Looks like the ESC needs a user certificate and key to establish SSL connection. Not sure how the ESC can be configured to access a dedicated user certificate & key? Can ESC detect and possibly use the TPS Admin cert/key if running on same platform? Ehansen @ SPYRUS Corp.
