I learned that I needed to create a header-handler.
Here's the code that got past the missing authorization header
problem...
require 'rubygems'
gem 'soap4r'
require 'defaultDriver.rb'
require 'soap/header/simplehandler'

class ClientAuthHeaderHandler < SOAP::Header::SimpleHandler
def initialize(userid, passwd)
namespace = "http://vmware.com/labmanager"
headername = "AuthenticationHeader"
header = XSD::QName.new(namespace, headername)
super(header)
@sessionid = nil
@userid = userid
@passwd = passwd
@mustunderstand = true
end
def on_simple_outbound
if @sessionid
{ "sessionid" => @sessionid }
else
{ "username" => @userid, "password" => @passwd }
end
end
def on_simple_inbound(my_header, mustunderstand)
@sessionid = my_header["sessionid"]
end
end

endpoint_url = nil
obj = VMware_interfaceSoap.new(endpoint_url)
obj.wiredump_dev = STDOUT

obj.options['protocol.http.ssl_config.verify_mode'] =
OpenSSL::SSL::VERIFY_NONE #ignore certificates for now
headerHandler =
ClientAuthHeaderHandler.new("myusername","mypassword")
obj.headerhandler.add( headerHandler )

puts obj.listConfigurations(nil)
