[Catalyst] Re: error when using Authentication::Store::Minimal

[Tommy Butler]

I found my own answer by looking at the source code for the MVC plugin. 
So much for the book.

The login method expects two strings: a username and a password.  Kudos
to the author who also made the method able to detect a username and
password based on best-guess, common sense logic of what they MIGHT be
based on the $c->request form parameter input.  Sadly, this was still no
match for the misinformation I was up against.  The login method doesn't
want a hashref at all, as we observe here in the source:
