将组从 LDAP 获取到 django

Question

我正在使用django-ldap-auth 针对LDAP-Server (ActiveDirectory) 对用户进行身份验证。用户能够登录并且每个用户的标志（例如 is_staff）设置正确。

我还想根据 ldap-users 组将 django-groups 添加到我的 django-users 中。这是我的设置：

import ldap
from django_auth_ldap.config import LDAPSearch, GroupOfNamesType, ActiveDirectoryGroupType

AUTH_LDAP_SERVER_URI = "ldap://XXX"

AUTH_LDAP_BIND_AS_AUTHENTICATING_USER = True
AUTH_LDAP_BIND_DN = ""
AUTH_LDAP_BIND_PASSWORD = ""

# I somewhere read that this should help, but it didn't:
#AUTH_LDAP_GLOBAL_OPTIONS = {
#    ldap.OPT_REFERRALS: 0
#}

AUTH_LDAP_USER_SEARCH = LDAPSearch("ou=Benutzer,ou=Konten,ou=XXX,ou=XXX,dc=XXX,dc=XXX,dc=XXX",
ldap.SCOPE_SUBTREE, "(cn=%(user)s)")
AUTH_LDAP_USER_DN_TEMPLATE = "CN=%(user)s,OU=Benutzer,OU=Konten,OU=XXX,OU=XXX,DC=XXX,DC=XXX,DC=XXX"

# Set up the basic group parameters.
AUTH_LDAP_GROUP_SEARCH = LDAPSearch("OU=AnwenderRollen,OU=Gruppen,OU=XXX,OU=XXX,DC=XXX,DC=XXX,DC=XXX",
    ldap.SCOPE_SUBTREE, "(objectClass=groupOfNames)"
)
AUTH_LDAP_GROUP_TYPE = GroupOfNamesType(name_attr="CN")
# also tried various possibilities for objectClass and AUTH_LDAP_GROUP_TYPE
#AUTH_LDAP_GROUP_TYPE = GroupOfNamesType(name_attr="cn")
#AUTH_LDAP_GROUP_TYPE = ActiveDirectoryGroupType(name_attr="cn")


# Populate the Django user from the LDAP directory.
AUTH_LDAP_USER_ATTR_MAP = {
    "first_name": "givenname",
    "last_name": "sn",
    "email": "mail"
}

AUTH_LDAP_PROFILE_ATTR_MAP = {
    #"employee_number": "employeeNumber"
}

AUTH_LDAP_USER_FLAGS_BY_GROUP = {
    #"is_active": "cn=active,ou=django,ou=groups,dc=example,dc=com",
    "is_staff": "CN=GROUPNAME,OU=AnwenderRollen,OU=Gruppen,ou=XXX,ou=XXX,dc=XXX,dc=XXX,dc=XXX",
    "is_superuser": "CN=GROUPNAME,OU=AnwenderRollen,OU=Gruppen,ou=XXX,ou=XXX,dc=XXX,dc=XXX,dc=XXX"
}

AUTH_LDAP_PROFILE_FLAGS_BY_GROUP = {
    #"is_awesome": "cn=awesome,ou=django,ou=groups,dc=example,dc=com",
}

# This is the default, but I like to be explicit.
AUTH_LDAP_ALWAYS_UPDATE_USER = True

# Use LDAP group membership to calculate group permissions.
AUTH_LDAP_FIND_GROUP_PERMS = True

# Cache group memberships for an hour to minimize LDAP traffic
AUTH_LDAP_CACHE_GROUPS = True
AUTH_LDAP_GROUP_CACHE_TIMEOUT = 1 #3600

# Keep ModelBackend around for per-user permissions and maybe a local
# superuser.
AUTHENTICATION_BACKENDS = (
    'django_auth_ldap.backend.LDAPBackend',
    'django.contrib.auth.backends.ModelBackend',
)

只有部分设置有效：登录有效，创建 django 用户，属性取自 LDAP (AUTH_LDAP_USER_ATTR_MAP)，并使用与 AUTH_LDAP_GROUP_SEARCH 中相同的组路径设置标志 (AUTH_LDAP_USER_FLAGS_BY_GROUP)。但是由于此错误，此组搜索不起作用：

DEBUG Populating Django user USERNAME
DEBUG search_s('CN=USERNAME,OU=Benutzer,OU=Konten,ou=XXX,ou=XXX,dc=XXX,dc=XXX,dc=XXX', 0, '(objectClass=*)') returned 1 objects: cn=USERNAME,ou=benutzer,ou=konten,ou=XXX,ou=XXX,dc=XXX,dc=XXX,dc=XXX

由于标志和组搜索的组路径相同，我假设它应该可以工作。绑定为认证用户时搜索组是否有问题？

我错过了什么？

Answer 1

这是我为使其工作所做的工作：

AUTH_LDAP_BIND_AS_AUTHENTICATING_USER = True
AUTH_LDAP_BIND_DN = "existing_user"
AUTH_LDAP_BIND_PASSWORD = "existing_password"

我将(objectClass=groupOfNames) 更改为(objectClass=top)

似乎django_auth_ldap 使用绑定用户检查标志（is_staff，...），但不检查组。所以我为这些变量添加了凭据，这些变量现在用于搜索组。

但是，它有效！

Answer 2

要将组从 ldap 镜像到 django，您可以将 AUTH_LDAP_MIRROR_GROUPS 标志设置为 True。这些组将在Groups 下创建，但您必须自己设置权限。这是我的示例配置：

"""
Ldap config. Have to set user as admin in django for successful login.
Using django_auth_ldap module
local settings should be loaded first to import env var settings
"""
import ldap
import os
import logging

from django_auth_ldap.config import LDAPSearch, PosixGroupType, LDAPGroupQuery

# Uncomment to enable verbose logging for ldap
# ldap.set_option(ldap.OPT_DEBUG_LEVEL, 4095)

AUTH_LDAP_SERVER_URI = os.getenv('LDAP_HOSTS', 'ldap://localhost')
logging.warning("LDAP host(s) is {}".format(AUTH_LDAP_SERVER_URI))

# Options
ldap_timeout = float(os.getenv('LDAP_TIMEOUT') or 10.0)
AUTH_LDAP_CONNECTION_OPTIONS = {
    ldap.OPT_REFERRALS: 0,
    ldap.OPT_NETWORK_TIMEOUT: ldap_timeout,
    ldap.OPT_TIMEOUT: ldap_timeout,
}

AUTH_LDAP_START_TLS = False
AUTH_LDAP_USER_DN_TEMPLATE = "cn=%(user)s,ou=employee,dc=mycompany,dc=com"
LDAP_AUTH_USER_LOOKUP_FIELDS = ("username", )

# Populate the Django user from the LDAP directory.
AUTH_LDAP_USER_ATTR_MAP = {
    'first_name': 'givenName',
    'last_name': 'sn',
    'email': 'mail',
}


IS_SUPER_USER_FLAG = (
        LDAPGroupQuery("cn=ldap-wheel,ou=groups,dc=mycompany,dc=com") |
        LDAPGroupQuery("cn=ldap-admin,ou=groups,dc=mycompany,dc=com") 
)

IS_STAFF_FLAG = (
        LDAPGroupQuery("cn=ldap-product,ou=groups,dc=mycompany,dc=com")
)

AUTH_LDAP_USER_FLAGS_BY_GROUP = {
    'is_active': IS_SUPER_USER_FLAG | IS_STAFF_FLAG,
    'is_staff': IS_SUPER_USER_FLAG | IS_STAFF_FLAG,
    'is_superuser': IS_SUPER_USER_FLAG,
}

AUTH_LDAP_GROUP_TYPE = PosixGroupType(name_attr='cn')
AUTH_LDAP_GROUP_SEARCH = LDAPSearch(
    'ou=groups,dc=mycompany,dc=com',
    ldap.SCOPE_SUBTREE,
    '(objectClass=posixGroup)',
)

AUTH_LDAP_ALWAYS_UPDATE_USER = True
AUTH_LDAP_FIND_GROUP_PERMS = True
AUTH_LDAP_CACHE_GROUPS = True

# Cache names and group memberships for an hour to minimize LDAP traffic.
AUTH_LDAP_CACHE_TIMEOUT = 3600

AUTH_LDAP_MIRROR_GROUPS = True  # Will sync ldap groups to django, if not exist
# AUTH_LDAP_MIRROR_GROUPS_EXCEPT except some groups we don't want to mirror in django

希望有帮助！
