[chef] Using shadow password on Windows

[Andrea Cappelli < >]

Ohai Chefs,
I have Windows 2008 R2 client with chef 11.4.4 installed through msi 
available on Opscode web site (http://www.opscode.com/chef/install.msi)

I would create users using shadow password, but for this I need the 
ruby-shadow gem, which seems not to be shipped with the installer

I tried to install using DevKit but without luck

Can anyone point me to some docs on how to install it?

Thanks
