How can I get Ruby SOAP :: RPC :: Driver to work with self-signed certificates?

Question

How to prevent this exception when calling soap on a server that uses a self-signed certificate?

require "rubygems"
gem "httpclient", "2.1.2"
require 'http-access2'
require 'soap/rpc/driver'
client = SOAP::RPC::Driver.new( url, 'http://removed' )
client.options[ 'protocol.http.ssl_config.verify_mode' ] = OpenSSL::SSL::VERIFY_NONE
client.options[ 'protocol.http.basic_auth' ] << [ url, user, pass ]

at depth 0 - 18: self signed certificate

Try:

client.options["protocol.http.ssl_config.verify_mode"] = nil
