LDAPError：（0，'Error'）和LDAPError：（2，'没有这样的文件或目录'）与瓶 [英] LDAPError: (0, 'Error') and LDAPError: (2, 'No such file or directory') with flask

问题描述

我试图实现LDAP。我正在使用以下为指导。
https://code.tutsplus.com / tutorials / flask-authentication-with-ldap -cms-23101 。根据下面的教程评论，我已经使用了

$
$ blockquote
current_user.is_authenticated：而不是
current_user.is_authenticated（）：

应用程序已启动，但是，当我尝试使用登录LDAP时出现以下错误。

  Traceback最近调用最后一次）：

我的LDAP提供程序URL我已经使用了以下两个选项：

  app.config ['LDAP_PROVIDER_URL'] ='xxx.xxxx .net / CN = xxx，DC = xxx，DC = xxx，DC = net'
  

/ p>

  app.config ['LDAP_PROVIDER_URL'] ='xxx.xxxx.net 
  

然而，我无法得到答案。我应该怎么做？

解决方案

有几件事你没有提到，我必须检查的是：

您是否将端口添加到您的PROVIDER_URL？

是否添加了完整格式：ldap：//ldap.testathon。 net：389 /？

最后，请确认LDAP实际上是在使用ldapsearch，如下所示：

  ldapsearch -x -LLL -h host.example.com -D用户-w密码-bdc = ad，dc = example，dc = com-s sub（objectClass = user ）givenName 
  

如果所有这些都可以，您需要将flask_app / my_app / init .py。

I am trying to implement LDAP. I am using following as guide. https://code.tutsplus.com/tutorials/flask-authentication-with-ldap--cms-23101.

According to comments below tutorial, I have used

current_user.is_authenticated: rather than current_user.is_authenticated():

Application started, however, I am getting following errors when I try to used login LDAP.

    result = func(*args,**kwargs)
LDAPError: (0, 'Error')

My LDAP Provider URL I have used alternatively following two option

app.config['LDAP_PROVIDER_URL'] = 'xxx.xxxx.net/CN=xxx,DC=xxx,DC=xxx,DC=net'

and

app.config['LDAP_PROVIDER_URL'] = 'xxx.xxxx.net

However, I am not able to get answer. What should I do ?

解决方案

A few things you have not mentioned, that i have to check is:

Did you add ports and such to your PROVIDER_URL?

Did you add the full format: ldap://ldap.testathon.net:389/ ?

Last, confirm that the LDAP is actually working with ldapsearch, like this:

ldapsearch -x -LLL -h host.example.com -D user -w password -b"dc=ad,dc=example,dc=com" -s sub "(objectClass=user)" givenName

If all of these are okay, you would need to post your "flask_app/my_app/init.py".
