python django域账号登录

要实现Django域账号登录，需要使用LDAP（轻量级目录访问协议）进行身份验证。以下是实现步骤：

1. 安装LDAP模块：

    pip install python-ldap

2. 在settings.py文件中添加如下配置：

    AUTHENTICATION_BACKENDS = (
        'django_auth_ldap.backend.LDAPBackend',
        'django.contrib.auth.backends.ModelBackend',
    )

    AUTH_LDAP_SERVER_URI = 'ldap://your_ldap_server_address'
    AUTH_LDAP_BIND_DN = 'your_bind_dn'
    AUTH_LDAP_BIND_PASSWORD = 'your_bind_password'
    AUTH_LDAP_USER_SEARCH = LDAPSearch(
        'your_base_dn',
        ldap.SCOPE_SUBTREE,
        '(sAMAccountName=%(user)s)',
    )
    AUTH_LDAP_USER_ATTR_MAP = {
        'first_name': 'givenName',
        'last_name': 'sn',
        'email': 'mail',
    }

3. 在urls.py文件中添加如下配置：

    from django.contrib.auth.views import LoginView

    urlpatterns = [
        path('accounts/login/', LoginView.as_view(
            template_name='admin/login.html',
            authentication_form=LDAPLoginForm,
        ), name='login'),
        ...
    ]

4. 创建LDAPLoginForm类，继承Django自带的AuthenticationForm类，实现LDAP身份验证：

    from django import forms
    from django.contrib.auth.forms import AuthenticationForm
    from django.contrib.auth import authenticate
    import ldap

    class LDAPLoginForm(AuthenticationForm):
        def clean(self):
            username = self.cleaned_data.get('username')
            password = self.cleaned_data.get('password')

            if not username or not password:
                raise forms.ValidationError('用户名和密码不能为空')

            ldap.set_option(ldap.OPT_X_TLS_REQUIRE_CERT, ldap.OPT_X_TLS_NEVER)
            ldap.set_option(ldap.OPT_REFERRALS, 0)
            ldap.set_option(ldap.OPT_PROTOCOL_VERSION, 3)
            ldap.set_option(ldap.OPT_X_TLS_CACERTFILE, '/path/to/ca.crt')

            try:
                l = ldap.initialize('ldap://your_ldap_server_address')
                l.simple_bind_s(username + '@your_domain_name', password)
                l.unbind()
            except ldap.INVALID_CREDENTIALS:
                raise forms.ValidationError('用户名或密码错误')
            except Exception as e:
                raise forms.ValidationError('无法连接到LDAP服务器')

            return self.cleaned_data

这样就可以实现Django域账号登录了。
