I meant to send this comment earlier in the day, I hope it is still useful:

FRAGMENT - not complete:
    my ($results, $err_page) = $self->check_rm('qs_display',
        {

I think it is pretty straightforward. I get the two passowrd values from my form, the trivial sub (which could be much simplified!) merely returns true or false. I am using D::FV 3.14 with CGI::Application

The code is not original, Cees Hek gave me the outline in an answer to a question on the CGI::App mail list.
