Answer 1

Ok, this should be easy. You need to, either enable auto_mapping in your config.yml or to manually specify "AcmeUserBundle: ~" there:
1) with auto_mapping
doctrine:
orm:
auto_mapping: true
2) without auto_mapping
doctrine:
orm:
mappings:
AcmeUserBundle: ~
Notice that if you are having multiple entity managers you won't be able to use auto_mapping feature.
Hope this helps!

Answer 2

It is also can help:
Add into your app/AppKernel.php:
...
new Acme\UserBundle\AcmeUserBundle(),
...

Answer 3

Add the following line to your app/AppKernel.php file's bundle array:
new FOS\UserBundle\FOSUserBundle()
This is to register that namespace for Symfony.

Answer 4

solucion for me:
change in ../Entity/User.php
namespace Acme\UserBundle\Entity; with namespace Acme\Bundle\UserBundle\Entity;
and in app/config.yml change
user_class: Acme\UserBundle\Entity\User with
user_class: Acme\Bundle\UserBundle\Entity\User
