从LDAP到django获取组

Question

我django-ldap-auth用来根据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)被正确设置.

我还想根据ldap-users组向我的django用户添加django-groups.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',
)

只有部分此设置有效:登录工作,创建django用户,属性取自LDAP(AUTH_LDAP_USER_ATTR_MAP),并设置标志(AUTH_LDAP_USER_FLAGS_BY_GROUP),其组路径与AUTH_LDAP_GROUP_SEARCH中相同.但是,这组搜索并没有因为这个错误的工作:

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

由于组路径对于标志和组搜索是相同的,我假设它应该工作.绑定为身份验证用户时搜索组是否有问题？

我错过了什么？

Answer 1

这是我为使其发挥作用所做的工作：

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

我(objectClass=groupOfNames)改为(objectClass=top)

似乎django_auth_ldap使用绑定用户来检查标志（is_staff，...），但不检查组。因此，我向这些变量添加了凭据，这些变量现在用于搜索组。

然而，它有效！
