Mongodb Symfony3+&引用；由于系统原因，无法处理身份验证请求；

我将Symfony3与MongoDB ODM一起使用。 当我尝试登录时，我收到一条消息：“由于系统问题，无法处理身份验证请求。”

以下是security.yml文件：

# To get started with security, check out the documentation:
# http://symfony.com/doc/current/security.html
security:
    encoders:
        PlannerBundle\Document\Account: sha512

        in_memory:
            memory: ~

    role_hierarchy:
        ROLE_ADMIN:       ROLE_USER

    firewalls:
        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: false

        admin:
            pattern: ^/admin
            form_login:

                check_path: login
                login_path: login
                default_target_path: sonata_admin_dashboard

            logout:
                path:   logout
                target: /admin/login

            anonymous:    true
            logout: true

    access_control:
        - { path: ^/admin/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/admin, roles: [ROLE_ADMIN, ROLE_COMMERCIAL] }

和实体文件：

use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;

此错误消息太笼统，您需要查看/logs/dev.log以查找您的具体问题。搜索错误文本，例如在我的例子中，它显示了“[Semantical Error]第0行，第44列靠近“username=：username”：错误：“username”未定义。“

然后我必须添加security.yml此

**”属性：username“**

下面这个示例的最后一行：

# To get started with security, check out the documentation:
# https://symfony.com/doc/current/security.html
security:
    encoders:
        AppBundle\Entity\User:
            algorithm: bcrypt

# https://symfony.com/doc/current/security.html#b-configuring-how-users-are-loaded
providers:
    db_provider:
        entity:
            class: AppBundle:User
            property: username

日志文件对错误有何说明？身份验证请求失败。{“异常”：“[对象]（Symfony\\Component\\Security\\Core\\exception\\AuthenticationServiceException（代码：0）：身份验证失败。at/data/bas/site/vendor/Symfony/Symfony/src/Symfony/Component/Security/Core/Authentication/Provider/DaoAuthenticationProvider.php:94，MongoConnectionException（代码：11）：身份验证失败。at/data/bas/site/vendor/alcaeus/mongophp适配器/lib/alcaeus/MongoDbAdapter/ExceptionConverter.php:83，MongoDB\\Driver\\Exception\\AuthenticationException（代码：11）：身份验证失败。at/data/bas/site/vendor/MongoDB/MongoDB/src/Operation/Find.php:219）}终于找到了解决方案！当您的连接具有用户名/密码时，您必须设置“authSource”参数@请在哪里设置“authSource”？
