Yep, I've been communicating offlist with another member, and he's
finally set me straight. Now I am using "openssl ca", and it is give
me the extensions the CSR is asking for.

I've got it almost all figured out, except how to get a subjectAltName
automatically populated by the CN of the requestor. My requests aren't
asking for a SAN, but Chrome isn't happy without one, so I'd like to
at least auto-populate 1 SAN by having it be the DNS:<CN> of the
requesting CSR.

Is that doable?
