Python-ldap 无法成功绑定(bind)

Question

我没有运气找到这个问题的答案，所以就这样吧。

当我尝试使用 python-ldap 连接到 AD 服务器时，它似乎对某些功能有效，但对其他功能无效。我的连接:

>>>import sys
>>>import ldap

>>>l = ldap.initialize("ldap://company.com:389")
>>>l.set_option(ldap.OPT_PROTOCOL_VERSION, 3)
>>>l.simple_bind_s("user@company.com","password")
(97, [], 1, [])

一些简单的谷歌搜索表明 97 意味着成功，尽管成功的程度有点不稳定。但是，出于某种原因，我在状态代码 1 上找不到任何内容。如果我在连接上运行一些 ldap 函数，其中一些可以工作，而另一些则不能。

>>>l.whoami_s()
'u:COMPANY.COM\\user'

似乎恢复正常，但是

>>> base_dn = 'dc=company,dc=com'
>>> retrieveAttributes = ["uniquemember"]
>>> searchFilter = "cn=user"
>>> l.search_s(base_dn, ldap.SCOPE_SUBTREE,searchFilter,retrieveAttributes)
Traceback (most recent call last):

    result = func(*args,**kwargs)

我很难理解为什么 whoami 可以工作，但搜索不能。我正在为用户使用域管理员，因此它不应该与目录权限有任何关系。任何人都可以解释一下吗？

Answer 1

我遇到了与您完全相同的错误，我所做的是在进行绑定(bind)之前添加这一行(如 Christopher 所建议的)，l.set_option(ldap.OPT_REFERRALS, 0)，例如

conn.protocol_version = ldap.VERSION3
conn.set_option(ldap.OPT_REFERRALS, 0)
conn.simple_bind_s(user, pw)

之后，我与 LDAP 的连接工作正常。
