ection from the wrapped old-style
        context factory.

        @note: Since old-style context factories don't distinguish between

            L{_ContextFactoryToConnectionFactory.serverConnectionForTLS}.

        @param protocol: The protocol initiating a TLS connection.
        @type protocol: L{TLSMemoryBIOProtocol}

        @return: a connection
        @rtype: L{OpenSSL.SSL.Connection}
