Using Apache SSPI:

Using LDAP:
http://www.ruby-forum.com/topic/55450#37973

A slightly different version using LDAP:

require 'net/ldap'
class User
  def self.authenticate(username, password)
    return false if username.to_s.size == 0
    return false if password.to_s.size == 0

    begin
      ldap = Net::LDAP.new(
        :host => AD_DOMAIN_CONTROLLER,
        :port => 389,
        :auth => {
          :method => :simple,
          :username => "#{username}", # <- AD UPN
          :password => "#{password}"
        }
      )
    rescue
      return false
    end

    ldap.bind ? User.find_by_login("#{username}") : nil
  end
end
