使用 Symfony 2.8 进行 LDAP 身份验证

Question

我正在尝试在 Symfony 2.8 中使用新的 LdapUserProvider。我相信我已经配置了一切 per the docs.

我的用户可以成功通过身份验证，然后被重定向到安全页面。重定向之后是问题开始的地方。 Symfony 尝试以经过身份验证的用户身份进行绑定，但密码为空，这被打开的 ldap 拒绝。

这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：

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

和日志文件：

Answer 1

我遇到了几乎完全相同的问题。经过紧张的调试，终于上线了：

在\Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken::__construct中：

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

这是一个问题，因为我诊断出 UsernamePasswordToken 即将从会话存储未经身份验证 开始。这是由于我自定义覆盖默认服务而没有分配角色造成的。

通常情况下，LDAP 只会在登录时调用一次，会话中不应存储密码。序列化令牌中只有 authenticated = true。

您确定您获得的是未序列化的经过身份验证的令牌吗？

Answer 2

终于找到问题所在了

您必须链接 UserProvider:

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

Answer 3

我遇到了同样的问题。在我的例子中，framework.session.handler_id 的配置错误——我不得不将其从本机文件处理程序更改为 null，这是默认的 PHP 会话处理程序。

Answer 4

在 Symfony 3.1 中，LdapClient 组件已被弃用。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
