Hi Jennifer,

Looks like you are missing the "password_field" config parameter:
http://search.cpan.org/~jayk/Catalyst-Plugin-Authentication-0.10006/lib/Catalyst/Authentication/Credential/Password.pm#CONFIGURATION

Also, you need to have the "id_field" set in your store configuration:
http://search.cpan.org/~jayk/Catalyst-Authentication-Store-DBIx-Class-0.104/lib/Catalyst/Authentication/Store/DBIx/Class.pm#CONFIGURATION

That would be the name of your username field in your MyDB::User class.

If you configure those items, you should be up and running.
Everything else looks fine.
