   ****** Information about Country, State or Province and City *****
   
   A two-letter country code, e.g., US, CA, DE etc. as defined by ISO 3166,
   is required. A state or province, and a city are also required.
   This locality information is included in two SSL certificates used internally
   by LON-CAPA, unless you are running standalone.
   
   If your server will be part of either the production or development
   clusters, then the certificate will need to be signed by the official
   LON-CAPA Certificate Authority (CA).  If you will be running your own
   cluster then the cluster will need to create its own CA.
