[Catalyst] Session example from Tutorial.pod doesn't work?

[catalyst]

I'm new to Catalyst and thought I'd start with the tutorial:
  http://search.cpan.org/~mstrout/Catalyst-5.63/lib/Catalyst/Manual/Tutorial.pod

I've gotten through most of the "Users and Authenticating" section and it's all working as advertised, but the last part (sessions) doesn't. >From the doc:

    To keep the user logged in, all we need to do is
    add the Session modules to our collection, and
    the Auth modules will automatically use them;

      use Catalyst qw/-Debug Static::Simple Authentication 
        Authentication::Store::Minimal 
        Authentication::Credential::Password
        Session Session::Store::File Session::State::Cookie/;

    Magic!

Unfortunately, the magic isn't working for me. When I call $c->login after a good login, the session apparently hasn't saved the credentials. What's more, when I look at

  Catalyst::Plugin::Authentication::Credential::Password::login()

I don't see any way that it could be using a session. It always wants a user and password to be explicitly passed or included in the CGI args.
