FOSUserBundle: Unrecognized field: usernameCanonical - symfony

Question

First of all, I know SO is full of questions like this but I tried to combine different config values according to those responses with no luck.
I'm using FOSUserBundle with my own User class and when submiting login form I get this error:
Unrecognized field: usernameCanonical
Here are some bits of my code:
doctrine:
auto_generate_proxy_classes: "%kernel.debug%"
naming_strategy: doctrine.orm.naming_strategy.underscore
auto_mapping: true
# mappings:
# FOSUserBundle: ~
fos_user:
service:
mailer: fos_user.mailer.twig_swift
db_driver: orm
firewall_name: main
user_class: AppBundle\Entity\User
Some variations tested include setting auto_mapping: false and/or uncommenting mappings.FOSUserBundle: ~
This is my user class:
<?php
namespace AppBundle\Entity;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Validator\Constraints as Assert;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;

Login (layout.html.twig actually) template has been overriden and apparently renders properly, my versions are:
Symonfy: Symfony version 2.8.2 - app/dev/debug
"friendsofsymfony/user-bundle": "^1.3"
console doctrine:schema:updatehas been executed and it doesn't detect any more changes, although usernameCanonical or email do not exist in the DB table.
Thanks

With FOSUserBundle 1.3.x you have to extend FOS\UserBundle\Entity\User instead of FOS\UserBundle\Model\User (see http://symfony.com/doc/1.3.x/bundles/FOSUserBundle/index.html#a-doctrine-orm-user-class).
