title: Provide username and password for chef recipe
body: <p>I'm using Chef's windows cookbook to provision some windows servers.  Here's the recipe:</p>
  
  <pre><code># Windows SDK for Windows 7 and .NET 4 - .NET Tools v4
  windows_package "Windows SDK for Windows 7 and .NET 4 - .NET Tools v4" do
      source "\\\\MyServer\\MyDrive\\chef\\WinSDKNetFx40Tools_amd64\\WinSDK_nfx40tools_amd64.msi"
      installer_type :msi
      action :install
  end
  </code></pre>
  
  <p>The problem is that I'm running into a permissions error when trying to access that UNC path.  Is it possible to provide a username/password to <code>windows_package</code> so I can tell it who to access the share as?  I've tried to store credentials via Credentials Manager, but that's not working.</p>
