The username of the account running the script can be accessed via something like:

puts ENV['USERNAME']

Beware that if you're running it as a system service the username will probably come back as "SYSTEM"

If that isn't enough to suite your needs there is an alternative method outlined here: https://stackoverflow.com/a/3544741/648695

You can use the Ruby etc module

require 'etc'
Etc.getlogin

The doc is avaiable here: http://ruby-doc.org/stdlib-2.0.0/libdoc/etc/rdoc/Etc.html#method-c-getlogin

Returns the short user name of the currently logged in user.

As far as I know, unless you're using active directory that would require a microsoft framework website, I don't think you'll find a way in rails.

There are a few discussion points here that may help: Can you get a Windows (AD) username in PHP?

Same question here: is there a way to read a clients windows login name using ruby on rails

Anyways, just copying my own answer below...

This is what worked for me but there are some limitations:

If you don't care about these issues, go ahead:

In your rails application, add Rekado's gem to your Gemfile: gem 'ntlm-sso', '=0.0.1'

Create an initialiser config/initializers/ntlm-sso.rb with:

require 'rack'
require 'rack/auth/ntlm-sso'

class NTLMAuthentication
  def initialize(app)
    @app = app
  end

  def call(env)
    auth = Rack::Auth::NTLMSSO.new(@app)
    return auth.call(env)
  end
end

On your application.rb file, add the line: config.middleware.use "NTLMAuthentication"
Call request.env["REMOTE_USER"] on your view or controller to get current username.

PS: Let me know if you find anyway to make it work on Chrome or to validate user credentials.
