Newbie Rails Authentication Woes

Hi All… Apologies in advance if this isn’t the right group (but I
couldn’t find a rails specific one) anyway -

I think I am having a problem passing data around in my MVC.

I have a view that looks has this in the middle:

<%= form_tag :controller => "login", :action => "login" %> DOMAIN\Username: <%= text_field(:login, :username) %> Password: <%= password_field(:login, :password) %> <%= end_form_tag %>

and here is my login_controller.rb

class LoginController < ApplicationController before_filter :authorize, :except => [:login, :logout]

def login
if request.get?
session[:username] = nil
else
#get the username and password from the array
username = params[:login][:username]
password = params[:login][:password]
# Split username on domain and alias
split_username = params[:user][:name].split(’\’,2)
if split_username.length != 2
flash[:notice] = “You did not enter a properly formatted domain
and username”
redirect_to :action => ‘login’
else
# Authenticate username and password
domain = split_username[0]
username = split_username[1]
password = params[:user][:password]
if authenticate domain, username, password
# User has been authenticated
session[:username] = username
else
flash[:notice] = “Incorrect username or password”
redirect_to :action => ‘login’
end
end
end
end

def logout
session[:username] = nil
end

require ‘dl/win32’
LOGON32_LOGON_NETWORK = 3
LOGON32_PROVIDER_DEFAULT = 0
BOOL_SUCCESS = 1
AdvApi32 = DL.dlopen(“advapi32”)
Kernel32 = DL.dlopen(“kernel32”)

def authorize
redirect_to( :controller => ‘login’, :action => ‘login’ ) unless
logged_in?
end

def logged_in?
session[:username] != nil
end

def authenticate(domain, username, password)
# Load the DLL functions
logon_user = AdvApi32[‘LogonUser’, ‘ISSSIIp’]
close_handle = Kernel32[‘CloseHandle’, ‘IL’]

# Normalize username and domain
username = username.strip.downcase
domain = domain.strip.downcase

# Authenticate user
ptoken = "\0" * 4
r,rs = logon_user.call(username, domain, password,

LOGON32_LOGON_NETWORK, LOGON32_PROVIDER_DEFAULT, ptoken)
success = (r == BOOL_SUCCESS)

# Close impersonation token
token = ptoken.unpack('L')[0]
close_handle.call(token)

session[:username] = username
return success

end
end

At the top of my application.rb I have:

class ApplicationController < ActionController::Base protected def authorize #changed from cookie to session unless session[:username] @session[:return_to] = @request.request_uri redirect_to :controller => "login" return false end end end

So the filtering works fine, when I try to access a protected page, it
goes to my login.rhtml.

but when I login, It craps out on me with this:

NoMethodError in LoginController#login

You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.[]

I swear I think everything is correct, but it isn’t working. I don’t
have any rails guru’s around, so I thought that I’d risk getting
roasted and post it here.
