Suggested approach.

1. Enter “rails LDAP authentication” into Google. Read the results.

2. If that doesn’t help, ask the question on a Rails mailing list.

The same question was questioned by me few months ago on this forums and  
you can search here for more informations.

This is my solution:

gem install ruby-net-ldap

add require ‘net/ldap’ =\> environment.rb

```
  ldap = Net::LDAP.new
  ldap.host = 'mydc.mydomain.com'
  ldap.port = 389
  ldap.auth "#{params[:usr]}@mydomain.com", params[:pass]
  unless ldap.bind
    flash[:error] = "Password or user incorect!"
    return false
  end

```

Works with Windows 2003 DC.
