825	NTLM option in upstream module allows authentication bypass	pantsman0@…		"When using the upstream module with ntlm authentication, users are able to bypass authentication by inheriting a backend connection for an authenticated user.

Connnections from a connection pool should not be returned when using ntlm authentication, as users are authenticated against that socket.

This has been observed in all tested browsers.
Tested browsers are:
* Chrome
* Firefox
* Internet Explorer 11
* Microsoft Edge
* Safari

All browsers are fully updated as of submission time.

Please find attached a sample configuration that imitates our testing environment where the issue occurs."	defect	closed	major		nginx-module	1.9.x	worksforme	upstream ntlm authentication bypass		Linux redacted.ap-southeast-2.compute.internal 2.6.32-573.7.1.el6.x86_64 #1 SMP Thu Sep 10 13:42:16 EDT 2015 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.9.4 (nginx-plus-r7-p1)
