=head1 DESCRIPTION

Role to manage local accounts, ensuring the usage of
L<Crypt::Passphrase> compatible ways of managing secrets.

This role I<demands> that the class implements method
C<load_user_by_name> with the following signature:

   sub load_user_by_name ($self, $controller, $name);

where C<$controller> is a L<Mojolicious::Controller> compatible class.
The return value from this method B<MUST> be a hash reference holding
the secret associated to the user identified by C<$name> in the value
corresponding to key C<secret>; this value is supposed to be a valid
value previously hashed with L<Crypt::Passphrase> or anything compatible
with it.
