cain$ perl -MCatalyst::Plugin::Authentication::Credential::Password -e 'print 
"Yay" if Catalyst::Plugin::Authentication::Credential::Password->can("login");'
Yay

After

__PACKAGE__->setup

try dumping @ISA out and see what you've got - if that's on your @ISA, check 
tutorial->can("login"), should return true.
