When installing subordinate CA with HSM, the installer calls the pki CLI (which is implemented using JSS) to validate the imported CA certificate in HSM. Normally, the HSM password is specified as CLI parameter, but in FIPS mode JSS requires both the HSM and the internal token passwords. Since the CLI only takes one password, JSS will prompt for the missing one on the console causing the installation to hang. As a temporary solution, the pki-server subsystem-cert-validate command has been modified to validate certificates stored in the internal token only and it will use the internal token password, so only a single password is required. Further investigation in CLI/JSS/NSS is needed to support validating certificates in HSM without password prompts. https://fedorahosted.org/pki/ticket/2543 -- Endi S. Dewata
