Zend framework2 如何使用回退设置多个身份验证适配器

我正在尝试设置ZfcUser，以便通过LDAP回退进行身份验证。我的zfcuser.global.php包含：

'auth_adapters' => array( 
    100 => 'ZfcUser\Authentication\Adapter\Db', 
    99 => 'ZfcUser\Authentication\Adapter\Ldap', 
),

我使用以下设置创建了一个Ldap.php作为抽象适配器。为了简洁起见，我删除了函数代码：

namespace ZfcUser\Authentication\Adapter;

use DateTime;
use Zend\Authentication\Result as AuthenticationResult;
use Zend\ServiceManager\ServiceManagerAwareInterface;
use Zend\ServiceManager\ServiceManager;
use Zend\Session\Container as SessionContainer;
use ZfcUser\Authentication\Adapter\AdapterChainEvent as AuthEvent;
use ZfcUser\Mapper\User as UserMapperInterface;
use ZfcUser\Options\AuthenticationOptionsInterface;


class Ldap extends AbstractAdapter implements ServiceManagerAwareInterface
{
    protected $mapper;
    protected $serviceManager;
    protected $options;

    public function authenticate(AuthEvent $e)
    {
        ...
    }

    public function getMapper()
    {
        ...
    }

    public function setMapper(UserMapperInterface $mapper)
    {
        ...
    }

    public function getServiceManager()
    {
        return $this->serviceManager;
    }

    public function setServiceManager(ServiceManager $serviceManager)
    {
        $this->serviceManager = $serviceManager;
    }

    public function setOptions(AuthenticationOptionsInterface $options)
    {
        $this->options = $options;
    }

    public function getOptions()
    {
        ...
    }  

}

我还将其作为可调用文件包含在Module.php文件中：

public function getServiceConfig()
{
    return array(
        'invokables' => array(
            'ZfcUser\Authentication\Adapter\Db' => 'ZfcUser\Authentication\Adapter\Db',
            'ZfcUser\Authentication\Adapter\Ldap' => 'ZfcUser\Authentication\Adapter\Ldap',
            ...
        ),
        ...
 }

如果我翻转优先级值，则会更改可以登录的用户。无论哪个适配器首先执行，都允许登录，但另一个适配器永远不会被使用。有人知道如果第一个适配器出现故障，如何让ZfcUser返回到下一个适配器吗？

问题已在此处修复

对我来说，我只是遵循matwright（github）的响应（请参阅），所以我替换了两个文件：

socalnick/src/ScnSocialAuth/Controller/Plugin/ScnSocialAuthProvider.php

socalnick/src/ScnSocialAuth/Controller/UserController.php

在zfcuser.global.php中：

“身份验证适配器”=>数组(
100=>ZfcUser\Authentication\Adapter\Db'，
),

希望这有助于
