errno32 LDAP Django管道损坏

Question

I'm currently trying to use my school's LDAP with a website built with Django. But i'm encountering an error that I'm not able to tackle.

When I am using my school's network the LDAP log in works perfectly on localhost. But when i am using an off-campus network the log-in doesn't work, even the admin login created when i've run manage.py for the first time doesn't work.

The terminal display's the following error each time i try to login :

Traceback (most recent call last):

Thank you very much for your help !

This is an issue with the Django devserver (you are running your website using it, which is not recommended at all for production websites).

Please see this ticket for more details:

According to many sources the 'Broken Pipe' is a normal browser quirk. For example, the browser reads from the socket and then decides that the image it's been reading apparently didn't change. The browser now this (forcefully) closes the connection because it does not need more data. The other end of this socket (the python runserver) now raises a socket exception telling the program that the client 'Broke the socket pipe'.

Short answer is: ignore this error since it's a known error and won't be fixed.

There is also this SO thread talking about this issue.
