经过身份验证的LDAP密码未存储在fos_user数据库中

我有一个注册和配置了FOSUserBundle和FR3DLdapBundle的Symfony项目，但是当我对测试LDAP服务器进行身份验证时，验证工作正常，但是当我查看dev.log时，Doctrine插入语句没有密码（它是空白的） .

这是我的config.yml文件的底部：

fr3d_ldap:
    driver:
        host: ldap.forumsys.com
    user:
        baseDn: dc=example, dc=com
        attributes:
            - { ldap_attr: uid,  user_method: setUsername }
            - { ldap_attr: mail,  user_method: setEmail }
            - { ldap_attr: userPassword,  user_method: setPassword }
        filter: (&(ObjectClass=person))

fos_user:
    db_driver: orm # other valid values are 'mongodb', 'couchdb' and 'propel'
    firewall_name: main
    user_class: AppBundle\Entity\User

我使用这个在线LDAP服务器来验证：http://www.forumsys.com/tutorials/integration-how-to/ldap/online-ldap-test-server/

这是我的User类：

/**
 * @ORM\Entity
 * @ORM\Table(name="fos_user")
 */
class User extends BaseUser implements LdapUserInterface
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\Column(type="string")
     */
    protected $dn;

    public function __construct()
    {
        parent::__construct();
        if (empty($this->roles)) {
            $this->roles[] = 'ROLE_USER';
        }
    }

    /**
     * {@inheritDoc}
     */
    public function setDn($dn)
    {
        $this->dn = $dn;
    }

    /**
     * {@inheritDoc}
     */
    public function getDn()
    {
        return $this->dn;
    }
}

当我使用例如“gauss”和密码“password”登录时出现主要问题，dev.log显示：

[2016-03-11 20:51:40] ldap_driver.DEBUG: {action}({base_dn}, {filter}, {attributes}) {"action":"ldap_search","base_dn":"dc=example, dc=com","filter":"(&(&(ObjectClass=person))(uid=gauss))","attributes":[]} []

[2016-03-11 20:51:41] doctrine.DEBUG: "COMMIT" [] []

请注意密码为空 . 我希望能够获取密码（即使它来自表单）并将其存储在数据库中 . 我想知道该怎么做 .

任何帮助/建议表示赞赏 .
