Symfony FOS user bundle initiation : <p>I have a problem with installing FOS user bundle. I tried to search it everywhere, but probably I'm too dumb and can't find it.</p>

<p>I've created an entity called Admin and tried to run doctrine:schema:update --force
I've got an error: <code>The child node "from_email" at path "fos_user" must be configured.</code>   </p>

<p>Here is my config.yml fos part.</p>

<pre><code>fos_user:
    db_driver: orm # other valid values are 'mongodb' and 'couchdb'
    firewall_name: main
    user_class: AppBundle\Entity\Admin
</code></pre>

<p>any suggestions?</p>
