Do you have multiple EntityManger defined in the config file(s) of your project? — Forer, Nov 29 '16 at 10:45

Autowiring feature is handy, but it has a limitations.

As you say, you have multiple instances of entity manager. So, Symfony doesn't know which of them should be injected into your services. If a service definition were available to change, you would set the autowiring_types parameter to specify a default implementation of dependency. But usualy entity manager services are defined by DoctrineBundle and you can not configure it directly. (As I know, Doctrine configuration doesn't provide options to set up that.)

So, the easiest way is to manually specify the entity manager: just pass a entity manager service ID (doctrine.orm.XXX_entity_manager) to constructor arguments of your services.

services:       
    app.security.user_login_form_authenticator:
        class: AppBundle\Security\UserLoginFormAuthenticator
        arguments: [ '@doctrine.orm.XXX_entity_manager' ]

    app.security.admin_login_form_authenticator:
        class: AppBundle\Security\AdminLoginFormAuthenticator
        arguments: [ '@doctrine.orm.YYY_entity_manager' ]

Obviously, if services have other dependendecies, you also need to specify them.
