Ruby-ldap gem does not work in rails3 application, but works in rails console

Question

I want to create a rails3 website with LDAP, so I chose the gem ruby-ldap (not net / ldap) that we used in our old rails2 applications and it works very well.

But I keep getting weird error in rails3 application, see codes below:

require 'ldap'
class WelcomeController < ApplicationController

  def index  
    begin
      @test = LDAP::Conn.new('10.72.64.11', 389)
    rescue LDAP::Error
      p LDAP::Error
    end  
    render :text => "ok"
  end
end 

welcome # index is my root route. In most cases, the application crashes when switching to LDAP :: Conn.new ('10 .72.64.11 ', 389), even I tried to use "pry" for debugging and tracking, throwing

[1]    24797 trace trap  rails s

and the WEBrick server will be terminated at this time.

Sometimes it throws a different type of error when I use "pry" for the step, #<NameError: uninitialized constant WelcomeController::LDAP>

During playback in the console, everything is going well.

1.9.3-p194 :001 > require 'ldap'
 => true 
1.9.3-p194 :002 > @test = LDAP::Conn.new('10.72.64.11', 389)
 => #<LDAP::Conn:0x00000101289568> 
1.9.3-p194 :003 > 

Can you steer me out of this crazy man? I am using ruby ​​1.9.3p194 and rails 3.2.8
