If I do not specify a join table on the many to many relation definition then doctrine schema valdiate command complains:

[FAIL] The entity-class AppBundle\Entity\Client mapping is invalid:

The field AppBundle\Entity\Client#users is on the inverse side of a bi-directional relationship, but the specified mappedBy association on the target-entity Application\Sonata\UserBundle\Entity\User#clients does not contain the required 'inversedBy="users"' attribute.

Code:

Annotations for the Client class

    /**
     * @var \Doctrine\Common\Collections\Collection|\Application\Sonata\UserBundle\Entity\User[]
     *
     * @ORM\ManyToMany(targetEntity="Application\Sonata\UserBundle\Entity\User", mappedBy="clients")
     */
    private $users;

XML for the User class
<many-to-many field="clients" target-entity="AppBundle\Entity\Client" inversed-by="users" />

Class looks likes:

    /** @var \Doctrine\Common\Collections\Collection|\AppBundle\Entity\Client[] */
    protected $clients;

If I change the xml definition like below, the validate command does not fail.

        <many-to-many field="clients" target-entity="AppBundle\Entity\Client" inversed-by="users">
            <join-table name="client_users">
                <join-columns>
                    <join-column name="client_id" />
                </join-columns>
                <inverse-join-columns>
                    <join-column name="user_id"/>
                </inverse-join-columns>
            </join-table>
        </many-to-many>
