In order for Connect to connect to Salesforce.com, the SSL client certificate must be
up-to-date. The Connect installation includes the file cacert.pem in the
<install_dir>/CACertificates directory. This is a plain text file
containing a set of public keys used for SSL authentication when connecting to
Salesforce.com.
If this file goes out-of-date, an HTTPSCVF error is issued when attempting to connect to
Salesforce.com. If that happens, go to http://curl.haxx.se/ca/cacert.pem, save the file as
cacert.pem to the <install_dir>/CACertificates
directory, and retry the Salesforce.com connection.
