如何在symfony2中更改用户提供者

Question

I changed to use two database in my application.

Originally, the user authentication was implemented by using the tables of a database named 'A'.

But I would like to change to the database called B.

No problem if you want to log in new, but in the case of login Remember Me, an error that there is no user provider will occur.

Is there a way to avoid this problem?

an example of the code is following:

・app/config/security.yml

original

security:
  providers:
    main:
      entity: { class: Acme¥DemoBundle¥Entity¥User }

changed

security:
  providers:
    main:
      entity: { class: Acme¥NewDemoBundle¥Entity¥NewUser }

Answer 1

Do you use two different EntityManagers?

Perhaps using the manager_name config option:

security:
  providers:
    main:
      entity: 
          class: Acme¥NewDemoBundle¥Entity¥NewUser 
          manager_name: entity_manager_name_for_database_B
