使用LDAP和DB在Symfony 5中进行多重身份验证 [英] Multiple authentication in Symfony 5 with LDAP and DB

问题描述

我想在Symfony 5中进行多重身份验证.第一个身份验证是LDAP.如果用户在里面就可以了.他将被连接.如果他不在，我想在用户存在的情况下在数据库中进行symfony检查.如果是，则将连接用户.

I woul'd like to do a multiple authentication in Symfony 5. The first authentication is LDAP. If the user is in it's ok. He will be connected. If he is not in I want symfony checks in DB if the user exists. If it's a yes so the user will be connected.

我尝试部署LDAP身份验证器和安全性验证器，但是...始终都是LDAP身份验证器起作用.永远没有安全感.

I tried to deploy LDAP authenticator and Security authenticator but... It's always LDAP authenticator who works. Never the security.

它如何工作以及我必须做什么?

How does it works and what I have to do ?

推荐答案

@Ping，您可以使用两个提供程序和两个防火墙，如下所示:

@Ping you can use two providers and two firewalls like below

    providers:
    db_provider:
        entity:
            class: UserBundle:User
            property: username
    hr_provider:
        entity:
            class: UserBundle:User
            property: username

firewalls:
    main:
        provider: db_provider
        pattern: ^/login|/logout|^/crm
        anonymous: ~
        form_login:
            default_target_path: contact_index
            login_path: login
            check_path: login
        logout:
            path: logout
            target: login
    hr_main:
        pattern: ^/signin|^/logoff|^/hr
        anonymous: ~
        provider: hr_provider
        form_login:
            default_target_path: hr_employee_leaves_balance
            login_path: hr_signin
            check_path: hr_signin
        logout:
            path: hr_logout
            target: hr_signin
