I'm not a Rails expert so I'm sure someone will step in and correct  
the following ;p

When you use map.resource Rails creates a set of RESTful routes for  
the resource in question, so when you hit the URL /users/login/ it's  
treating login as the parameter to pass to the show method of the  
UsersController controller as opposed to looking for the  
Users::LoginController that you intend.

A simple solution would be to define a named route for /users/login/  
prior to map.resource :users as the named route would take precedence,  
however if you're looking to make your application RESTful a better  
choice of URL scheme might be /session/[create|show|list|etc.] and  
treat the session itself as a RESTful entity.

Hopefully that's intelligible :)
