Using Apache SSPI:

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