undefined method `confirm_password' - does this imply AuthLogic isn't triggering for my request?

Hi,

Pretty much have the [Authlogic example -
http://github.com/binarylogic/authlogic_example ] type rails app
setup. I'm
getting the following error when I click on the registered link. From
a generic point of view I can't quite see how the view "form.label
:confirm_password" is support to run without raising an issue, noting
that this field does not exist in the User table in the database?

Q1 - How is AuthLogic supposed to stop this form "confirm_password" not
to be passed right back to the mode?

Q2 - Any ideas what is going wrong in my case below and how to address
it? How does generally Rails handle ignoring a "confirm_password"
type field in a form when processing, in the way that it (a) is
required at the controller stage but (b) not required at the backend
active_record stage.

got it - had to change it to ":password_confirmation" and it worked -
was an AuthLogic thing....
