[T. H. Lin]

MyApp.pm
=========
use Catalyst qw/-Debug
                ConfigLoader
                Static::Simple
                DefaultEnd
                Authentication
                Authentication::Store::DBIC
                Authentication::Credential::Password
                I18N/;
__PACKAGE__->setup;
======================

MyApp/Controller/Login.pm
======================
sub begin : Private {
    my ( $self, $c ) = @_;
    $c->config->{authentication}{dbic} = {
        user_class               => 'DBIC::User',
        user_field                 => 'name',
        password_field        => 'pass',
        password_type         => 'hashed',
        password_hash_type => 'SHA-256',
    };
}
sub default : Private {
    my ( $self, $c ) = @_;

    if (    my $user     = $c->req->param("user")
        and my $password = $c->req->param("password") )
    {
        if ( $c->login( $user, $password ) ) {
            $c->res->body( "hello " ) . $c->user->name );
        } else {  ... }
    }
    else { ..  }
}
=========================================

then I connect to /account
ERROR
Caught exception in MyApp::Controller::Account->default "Can't call
method "search" on an undefined value at
/usr/local/lib/perl5/site_perl/5.8.8/Catalyst/Plugin/Authentication/Store/DBIC/User.pm
line 15."

??why Catalyst/Plugin/Authentication/Store/DBIC/User.pm ??
I see the code, there is something like... $config->{auth}

I try to dump my $c->config
$c->config->{auth} is undef!
