Definitions should allow access to the node object within the parameter setting block

1. attributes
   nagios Mash.new
   nagios[:users] = Array.new
   nagios[:users] << {:username => "admin", :password => "whatever"}

define :add_htpasswd_users do
params[:users].each do |auth|
execute "add_htpasswd_#{auth[:username]}" do
command "echo '#{auth[:username]}:#{auth[:password]}' >> #{params[:name]}"
not_if do
if File.exists?(params[:name])
File.open(params[:name]) do |password_file|
password_file.detect { |line| line =~ /#{auth[:username]}:#{auth[:password]}/ }
end
end
end
end
end
end

The following works:

blah = node[:nagios][:users]
add_htpasswd_users "/tmp/out" do
users(blah)
end

This one however doesn't work, and raises a weird TypeError

add_htpasswd_users "/tmp/out" do
users(node[:nagios][:users])
end
