我尝试启动我的Django项目，但我发现了这个错误：
Traceback (most recent call last):

ldap.OPT_X_TLS_REQUIRE_CERT: ldap.OPT_X_TLS_NEVER
AttributeError: module 'ldap' has no attribute 'OPT_X_TLS_REQUIRE_CERT'
我使用Python 3.5，Django 1.11.7，ldap 1.0.2
当我删除我的本地项目并再次从github克隆时，就会发生这种情况。我像往常一样安装了所有要求。
部分代码：
import os
import ldap
from django_auth_ldap.config import LDAPSearch, ActiveDirectoryGroupType
....
AUTH_LDAP_GLOBAL_OPTIONS = {
ldap.OPT_X_TLS_REQUIRE_CERT: ldap.OPT_X_TLS_NEVER
}
