django-auth-ldap 身份验证失败 [英] django-auth-ldap failed authentication

问题描述

我正在尝试在我的项目(Django 1.6, Python 2.7) 但它不工作.

I'm trying to use Django-Auth-Ldap in my project (Django 1.6, Python 2.7) but it is not working.

我的 Active Directory shema 是:

My active Directory shema is:

1. 我已经通过安装 ldap-utils 包在 cmd 行测试了连接

1. I've tested the connection on the cmd line by installing the ldap-utils package

sudo apt-get install ldap-utils

ldapsearch -H ldap://domain.com -D "ou=Resources,ou=Company, dc=domain,dc=com" -U "user_name" -w "user_password" -v -d 1

连接测试工作正常.

1. 我正在使用以下代码从 shell 测试 python-ldap 连接:

1. I am using below code to test python-ldap connection from the shell:

import ldap

con = ldap.initialize('ldap://domain.com')

con.simple_bind_s('User_mail', 'User_password')

results = con.search_s('ou=Users,ou=Resources,ou=Company,dc=domain,dc=com', ldap.SCOPE_SUBTREE, "(cn=User_name)")

python-ldap 连接工作正常.

python-ldap connection works fine.

1. 我的问题是如何从我的 django 登录界面对 AD 用户进行身份验证?

settings.py:

settings.py:

import ldap 
from django_auth_ldap.config import LDAPSearch

# The URL of the LDAP server.
AUTH_LDAP_SERVER_URI = "ldap://domain.com"
AUTH_LDAP_BIND_DN = "cn='User_name',ou=Resources,ou=Company,dc=domain,dc=com"   
AUTH_LDAP_BIND_PASSWORD = "User_password"
AUTH_LDAP_USER_SEARCH = LDAPSearch("ou=Users,ou=Resources,ou=Company,dc=domain,dc=com",ldap.SCOPE_SUBTREE, "(cn=%(user)s)")    
AUTH_LDAP_GLOBAL_OPTIONS = { ldap.OPT_REFERRALS : False }

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

views.py:

from django_auth_ldap.backend import LDAPBackend
auth = LDAPBackend()
user = auth.authenticate(username="User_name", password="User_password")

在文件 django-ldap-debug.log 我有这个错误:

In the file django-ldap-debug.log I have this error:

Caught LDAPError while authenticating User_name: INVALID_CREDENTIALS({'info': '80090308: LdapErr: DSID-0C0903A9, comment: AcceptSecurityContext error, data 52e, v1db1', 'desc': 'Invalid credentials'},)

推荐答案

我找到了答案.

我通过添加 (OU=Users)

I changed the AUTH_LDAP_BIND_DN by adding (OU=Users)

我必须在 AUTH_LDAP_USER_SEARCH 中使用 samAccountName 而不是 CN

I must use samAccountName instead of CN in AUTH_LDAP_USER_SEARCH

我的新设置.py:

import ldap, logging
from django_auth_ldap.config import LDAPSearch

logger = logging.getLogger('django_auth_ldap')
logger.addHandler(logging.StreamHandler())
logger.setLevel(logging.DEBUG)

AUTH_LDAP_SERVER_URI = "ldap://domain.com"
AUTH_LDAP_BIND_DN = "CN=User_name,OU=Users,OU=Resources,OU=Company,DC=domain,DC=com"
AUTH_LDAP_BIND_PASSWORD = "User_password"
AUTH_LDAP_USER_SEARCH = LDAPSearch("OU=Users,OU=Resources,OU=Company,DC=domain,DC=com",ldap.SCOPE_SUBTREE, "(samAccountName=%(user)s)")

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

我的意见.py

from django_auth_ldap.backend import LDAPBackend

def login(request):  
    if request.method == 'POST':
        form = MyLoginForm(data=request.POST)
        if form.is_valid():
            username = form.cleaned_data['username']
            password = form.cleaned_data['password']            
            auth = LDAPBackend()
            user = auth.authenticate(username=username, password=password)
            if user is not None:
                ....
    else:
        form = MyLoginForm()

    ....
