Symfony 2 Must Implement UserProviderInterface - php

Question

I get this error 'Must implement UserProviderInterface'
when trying to using the symfony login features. I'm referencing the repository * #ORM\Entity(repositoryClass="Login\LogBundle\Entity\Repository\UserRepository") . Does anyone have any ideas.

Answer 1

Check the app/config/security.yml file with something like this:
# app/config/security.yml
security:
providers:
main:
entity:
class: Acme\UserBundle\Entity\User
property: username
And path to repositoryClass UserRepository is wrong, maybe you mean this:
#ORM\Entity(repositoryClass="Login\LogBundle\Entity\UserRepository")
becouse you use namespace \Login\LogBundle\Entity\UserRepository.

Answer 2

To load user from Repository, you should omit the { property: username } from security.yml.
