User Engine : undefined method `find_by_login' for User:Class

Hello all,

I’ve installed plugins Engines, Login Engine, User Engine, and db:migrate:engines successfully.

undefined method `find_by_login’ for User:Class

Someone have a suggestion of what I have misconfigured ?

Thank you for your advice!
