Question

我试图在Symfony 2.8中使用新的LdapUserProvider。我相信我已配置了所有内容per the docs。

我的用户可以成功进行身份验证，然后重定向到受保护的页面。重定向后问题开始。 Symfony尝试绑定为经过身份验证的用户，但使用空密码，open ldap会拒绝该密码。

以下是相关的日志条目和配置值。

配置：

services:
    app.ldap:
        class: Symfony\Component\Ldap\LdapClient
        arguments: [ "localhost" ]

安全性：

security:
    firewalls:
        restricted_area:
            provider: app_users
            form_login_ldap:
                service: app.ldap
                dn_string: "uid={username},DC=mydomain,DC=net"
                check_path: login_check
                login_path: login
    providers:
        app_users:
            ldap:
                service: app.ldap
                base_dn: dc=mydomain,dc=net
                search_dn: cn=Manager,DC=mydomain,DC=net
                search_password: secretPassword
                filter: "(&(aptAccountEnabled=1)(ObjectClass=aptAccount)(uid={username}))"
                default_roles: ROLE_USER

Answer 1

最后我发现了问题所在。

您必须链接UserProvider：

chain_provider:
    chain:
             providers: [in_memory, app_users]
    in_memory:
        memory: ~
    app_users:
        ldap:
           .....</i>

Answer 2

我有同样的问题。在我的情况下，它是framework.session.handler_id的错误配置 - 我不得不将其从原生文件处理程序更改为null，这是默认的PHP会话处理程序。

Answer 3

我几乎完全一样的问题。经过紧张的调试，我来到了这一行：

\Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken::__construct中的

：

parent::setAuthenticated(count($roles) > 0);

这是一个问题，因为我诊断出，UsernamePasswordToken是从未经身份验证的会话存储开始的。这是由于我的自定义覆盖默认服务而未分配任何角色造成的。

通常，LDAP在登录时只会被调用一次，并且会话中不应存储密码。序列化令牌中只有authenticated = true。

您确定要获得反序列化的经过身份验证的令牌吗？

在Symfony 3.1中，不推荐使用LdapClient组件。所以我想更新解决方案。此解决方案也适用于Symfony 2.8 / 2.9应用程序。

#security.yml
security:
    firewalls:
        restricted_area:
            provider: app_users
            form_login_ldap:
                service: ldap.auth
                dn_string: "%dn_string%"

    providers:
        app_users:
            ldap:
                service: ldap.auth
                base_dn: "dc=domain,dc=net"
                search_dn: "cn=Manager,DC=domain,DC=net"
                search_password: secretPassword
                filter: "(&(aptAccountEnabled=1)(ObjectClass=aptAccount)({uid_key}={username}))"
                default_roles: ROLE_USER
                uid_key: uid

#services.yml
services:
    ldap.auth:
        class: 'Symfony\Component\Ldap\Ldap'
        factory:
            - 'Symfony\Component\Ldap\Ldap'
            - 'create'
        arguments:
            - 'ext_ldap'  # adapter
            -
              host: database
              options:
                  protocol_version: 3

使用Symfony 2.8进行LDAP身份验证
