Starting with Cosign 0.9.0, which will be released in the next few
days, I'm going to need the subject of the certificate your clients are
using to talk to cosignd. This is generally the hostname of your
webserver. If you have any questions, send 'em to cosign@xxxxxxxxx and
we can clarify. While you're at it, send me the service name you are
using as well.
Look for a release announcement in the next few days.
