I have a main app that has a users table. Now I want to make another  
app that supports/extends the main app. I would like to authenticate  
the supporting app with the main app user’s table. How do I begin  
this?

Create a User activeresource model in the supporting app?  
Copy the authentication code in my main app into the supporting app?

What is the best way to go about doing this?

Thanks for any help!
