If all you want to do is redirecting the user to /login if he isn't
logged in you could try CatalystX::SimpleLogin.
Using auto for that stuff is kinda deprecated according to what I
overheard in the irc channel.

I couldn't find an error in what little information you have provided.
I'd probably go and

-) check if all relevant modules are up to date.
-) try with a different browser
-) create a simple app and try this particular code there.
