在Django中使用LDAP进行身份验证

2023-04-11 00:00:00 django ldap 身份验证

安装ldap模块：

pip install ldap3

在Django的settings.py文件中配置LDAP：

import ldap3

AUTHENTICATION_BACKENDS = [
    'django_auth_ldap.backend.LDAPBackend',
    'django.contrib.auth.backends.ModelBackend',
]

# LDAP认证设置
AUTH_LDAP_SERVER_URI = 'ldap://ldap.example.com:389'
AUTH_LDAP_BIND_DN = 'cn=admin,dc=example,dc=com'
AUTH_LDAP_BIND_PASSWORD = 'password'
AUTH_LDAP_USER_SEARCH = ldap3.ObjectDef(
    'dc=example,dc=com',
    ldap3.constants.SUBTREE,
    '(uid=%(user)s)',
    ['uid', 'cn', 'mail', 'group']
)

# 设置用户属性映射
AUTH_LDAP_USER_ATTR_MAP = {
    'username': 'uid',
    'first_name': 'cn',
    'email': 'mail',
    'groups': 'group',
}

# 分组映射
AUTH_LDAP_GROUP_TYPE = ldap3.AD_GROUP_TYPE_GLOBAL_GROUP
AUTH_LDAP_MIRROR_GROUPS = True
AUTH_LDAP_GROUP_SEARCH = ldap3.ObjectDef(
    'ou=Groups,dc=example,dc=com',
    ldap3.constants.SUBTREE,
    '(objectClass=groupOfNames)',
    ['cn', 'member']
)

# 设置群组属性映射
AUTH_LDAP_GROUP_TYPE_PARAMS = {
    'name_attr': 'cn',
    'member_attr': 'member',
    'user_relation': ldap3.AD_MEMBER_OF,
}

# 启用TLS
AUTH_LDAP_START_TLS = True

创建一个AuthView视图，用于处理身份验证请求：

from django.views.generic import View
from django.shortcuts import render, redirect
from django.contrib.auth import authenticate, login, logout


class AuthView(View):
    template_name = 'auth.html'

    def get(self, request):
        if request.user.is_authenticated:
            return redirect('home')
        return render(request, self.template_name)

    def post(self, request):
        username = request.POST.get('username')
        password = request.POST.get('password')
        user = authenticate(request, username=username, password=password)

        if user is not None:
            login(request, user)
            return redirect('home')
        else:
            return render(request, self.template_name, {'error': 'Invalid credentials'})

创建一个logout视图，用于处理用户注销请求：

from django.contrib.auth import logout
from django.shortcuts import redirect


def logout_view(request):
    logout(request)
    return redirect('login')

在urls.py文件中添加路由：

from django.urls import path
from .views import AuthView, logout_view

urlpatterns = [
    path('', AuthView.as_view(), name='login'),
    path('logout/', logout_view, name='logout'),
]

在模板中添加登录表单：

<form method="post">
    {% csrf_token %}
    <div class="form-group">
        <label for="username">用户名</label>
        <input type="text" name="username" class="form-control" id="username" placeholder="请输入用户名">
    </div>
    <div class="form-group">
        <label for="password">密码</label>
        <input type="password" name="password" class="form-control" id="password" placeholder="请输入密码">
    </div>
    {% if error %}
        <div class="alert alert-danger">{{ error }}</div>
    {% endif %}
    <button type="submit" class="btn btn-primary">登录</button>
</form>
