Currently when installing an additional subsystem to an existing instance the install tool always generates a new random password in the pki_pin property which would not work with the existing NSS database. The code has been modified to load the existing NSS database password from the instance if the instance already exists. The PKIInstance class has been modified to allow loading partially created instance to help the installation. https://fedorahosted.org/pki/ticket/2247 -- Endi S. Dewata
