Python LDAP and Active Directory issue(Python LDAP 和 Active Directory 问题)

本文介绍了Python LDAP 和 Active Directory 问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我会尽量包含尽可能多的细节，但请考虑这种情况:

I'll try to include as much detail as possible but consider this situation:

出于隐私考虑，假设我有一个如下所示的 Active Directory 基础架构:

For privacy concerns lets say I have an Active Directory infrastructure like the following:

microsoft.com
和一些子域:
csharp.microsoft.com
vb.microsoft.com

microsoft.com
and some child domains:
csharp.microsoft.com
vb.microsoft.com

所有用户帐户都存储在 microsoft.com.

All user accounts are stored at microsoft.com.

我的代码如下:

import ldap
ldap.set_option(ldap.OPT_REFERRALS,0)
ldap.set_option(ldap.OPT_X_TLS_REQUIRE_CERT,ldap.OPT_X_TLS_NEVER)

(我知道我可能应该有一个域的证书，但你能做什么)

(I know I should probably have a certificate for the domain, but what can you do)

然后我建立如下连接:

conn = ldap.initialize("ldaps://microsoft.com:636")
conn.simple_bind_s("user","pass")

在我的脚本中，我正在搜索用户帐户，并使用以下搜索:

In my script I am searching for a user account, and I use the following search:

result_id = conn.search("DC=microsoft,DC=com",
                                ldap.SCOPE_SUBTREE,
                                "(&(CN=gates)(!(objectClass=contact)))",
                                None)
result_type,result_data = conn.result(result_id,0)

好的，所以这行得通......大部分时间.
当它起作用时，我会得到一些效果:

Ok great, so this works....most of the time.
When it does work I get something to the effect of:

[("CN=gates,OU=Users,DC=microsoft,DC=com", {'sAMAccountName':['gates']}])

然而，似乎随机，我会得到如下结果:

However, it seems at random, that I will get results like the following:

[(None, ['ldaps://csharp.microsoft.com/DC=csharp,DC=microsoft,DC=com'])]

虽然结果是有道理的——在 csharp.microsoft.com 上不存在 gates，但在 microsoft.com DC 上存在——这仍然很令人费解，因为我的印象是使用 OPT_REFERRALS 设置为 0 会告诉 Python LDAP 模块不要使用推荐.为了让事情变得更有趣，我有时也会得到如下结果:

While the result makes sense - gates does not exist at csharp.microsoft.com he exists at microsoft.com DC - it is still very puzzling because I am under the impression that using OPT_REFERRALS setting to 0 will tell the Python LDAP module to NOT use referrals. To make things more interesting I also sometimes get results like the following:

[(None, ['ldaps://ForestDnsZones.microsoft.com/DC=ForestDnsZones,DC=microsoft,DC=com'])]

所以我的问题 - 我做错了什么吗?

So my question - is there anything I'm doing wrong?

此外，有人建议，如果我使用OU=Users,DC=microsoft,DC=com"之类的搜索路径，而不是仅从根目录(DC=microsoft,DC=com")搜索LDAP 客户端模块不会尝试使用引用 - 这是否准确?

Also, it has been suggested that if I use a search path like "OU=Users,DC=microsoft,DC=com" instead of just searching from the root ( "DC=microsoft,DC=com" ) that the LDAP client module will not attempt to use referrals - is this accurate?

编辑

结果证明问题与 LDAP 无关，而是与 WSGI 配置错误有关.使用 WSGIDaemonProcess 解决了我们遇到的交叉污染问题.

The issue turned out to not be LDAP related but rather a WSGI mis-configuration. Using the WSGIDaemonProcess solved the cross contamination issue we were experiencing.
