How to make OAuth authorization through Symfony2 personal login and password?

Question

symfony

Symfony2.4 on the server (RestBundle + OAuthServerBundle) OAuth is needed more for authorization than integration with services.
The catch is this: it is not possible to make authorization using only a login and password (it was possible to do it through keys, but this does not work).
How can this be implemented?
