 I love, love, love the Cyberduck but have recently found a bug in the way
 it evaluates the trustworthiness of SSL certificates.  It checks only the
 Common Name for a match on the server name but ignores the subjectAltName
 extensions, which are a perfectly valid and common way to secure
 additional domain names under one certificate.  I'd love to see this added
 to a future Cyberduck update as the alternative is to add a bunch of
 explicit certificate trusts to your Keychain when working with sites
 secured this way.  Attached are screenshots of what Cyberduck does when
 connecting to an FTP URL which is secured in the subjectAltName of a
 certificate with a different Common Name.
