Question

我正在尝试实施LDAP。我使用以下作为指导。 https://code.tutsplus.com/tutorials/flask-authentication-with-ldap--cms-23101

根据以下教程的评论，我使用了

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，我遇到以下错误。

LDAPError: (0, 'Error')

我的LDAP提供程序URL我已经选择使用两个选项

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

和

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

但是，我无法得到答案。我该怎么办？

Answer 1

你还没有提到的一些事情，我必须检查：

您是否在PROVIDER_URL中添加了端口等等？

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

最后，确认LDAP实际上正在使用ldapsearch，如下所示：

dotnet new

如果所有这些都没问题，您需要发布“flask_app / my_app / init .py”。

Answer 2

我遇到了类似的问题。我设法解决了这个问题：

我改变了

connect = ldap.initialize("x.x.x.x")

对此

connect = ldap.initialize("ldap://x.x.x.x")

LDAPError：（0，＆＃39;错误＆＃39;）和LDAP错误：（2，＆＃39;没有这样的文件或目录＆＃39;）带烧瓶
