Kerberos login stopped working in Python scripts[error 401]

[Alexey Chistyakov]

Hello!

jira-python
In my python scripts using JIRA API, kerberos authentication suddenly stopped working(authentication worked for months and then suddenly stopped working in the evening).

There was no update of the python libraries. Error occurs on different versions of the python jira library, on different hosts and for different jira(and kerberos) users.

Curl can log into JIRA using kerberos!!!

Im using standard library connection:

JIRA(server=jira_server, kerberos=True)

Same problem with confluence rest api. Kerberos autentification stop work. Basic autentification works well in the same time. 
The problem is not in JIRA (or CONFLUENCE) module. I've tried with requests python lilbrary.  No autentification received. 

Autentification stopped working a couple days ago.

by any chance, did you get it working with Kerberos authentication?
