如何使用django-auth-ldap实现身份验证?

标签: django ldap django-authentication openldap django-auth-ldap

我有一个使用django运行的应用。 现在我只想通过openldap服务器进行身份验证的用户看到“他们的视图”(因此我在成功验证后只需要他们的uid)

我如何实现这一目标?

我想django-auth-ldap是要走的路,所以我整天都试着去了解身份验证实际发生的位置,以及如何让用户的uid请求查看。

我使用documentation for the settings.py,但我找不到如何“实际使用”它。也许有人可以指出我正确的方向?

settings.py:

import ldap

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

AUTH_LDAP_SERVER_URI = "ldap://123.60.56.61"

AUTH_LDAP_BIND_DN = ""
AUTH_LDAP_BIND_PASSWORD = ""
AUTH_LDAP_USER_DN_TEMPLATE = "uid=%(user)s,dc=rd,dc=corpintra,dc=net"

(顺便说一下:我已经可以使用python-ldap执行ldap-searche并在命令行中获得类似ldapsearch的结果,所以其他一切工作正常......)

我的观点需要什么?

感谢您的帮助!

以下是我们其中一个网站的摘录。

# Django Auth Ldap
main_dn = 'dc=____,dc=organisation,dc=com'
groups_dn = 'ou=Groups,'+main_dn
users_dn = 'ou=Users,'+main_dn

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

AUTH_LDAP_SERVER_URI = "ldap://ldap.organisation.com"
AUTH_LDAP_BIND_DN = 'cn=___,'+main_dn
AUTH_LDAP_BIND_PASSWORD = "__________________"
AUTH_LDAP_USER_SEARCH = LDAPSearch(users_dn, 2, "(uid=%(user)s)")
AUTH_LDAP_USER_ATTR_MAP = {
    "first_name": "givenName",
    "last_name": "sn",
    "email": "mail"
}
AUTH_LDAP_MIRROR_GROUPS = True
AUTH_LDAP_ALWAYS_UPDATE_USER = True
AUTH_LDAP_GROUP_TYPE = PosixGroupType()
AUTH_LDAP_GROUP_SEARCH = LDAPSearch(groups_dn, ldap.SCOPE_SUBTREE, "(objectClass=posixGroup)")

AUTH_LDAP_USER_FLAGS_BY_GROUP = {
    "is_staff":         "cn=admins,"+groups_dn,
    "is_superuser":     "cn=developers,"+groups_dn,
}

编辑:

由于问题是“我的观点中需要什么?”,答案是此配置会将用户的uid保存为用户模型上的用户名字段,因此在您的视图中,您需要

uid = request.user.username

希望这可以让你开始运行。

由于django-auth-ldap是一个普通的Django身份验证后端,request.user应该设置为经过身份验证的用户(假设您已经安装了标准中间件 - 请参阅Django文档)。通过典型设置,request.user.username将是用户DN的uid。如果您需要更多信息,可以从request.user.ldap_user获取。

我没有使用django-auth-ldap,我自己写了ldap authentification后端。

#define your backend authentification
AUTHENTICATION_BACKENDS = (
    'netipa.managment.ldapwm.netipaldapdjango.NetIpaLdap',
    #'django.contrib.auth.backends.ModelBackend ',
)

            return User.objects.get(pk=user_id)
        except User.DoesNotExist:
            return None

这是我的扩展用户类模型

from django.db import models
from django.contrib.auth.models import AbstractUser

# Create your models here.

class LdapUsers(AbstractUser):
    ldap_id = models.IntegerField()
    ldap_mail = models.EmailField()
