Buenas amigos aca de nuevo  molestando, instale openvpn, phpki y openvpn bridge, despuede de horas y horas batallando con algo que en teoria es bastante simple he tenido para crear certificado VPN tanto server como cliente o de cualquier tipo, ahora cuando intento crear un certificado me encuentro con el siguiente error:
There was an error updating the Certificate Revocation List.
Debug Info:
Generating Certificate Revocation List.
Using configuration from /opt/phpki/phpki-store/config/openssl.cnf
unable to load CA private key

voy a la dirección /opt/phpki-store/config/openssl.cnf abirendo el archivo para modificarlo solo encuentro lo siguiente:
