我已经在带有WinBind和Samba的Ubuntu 16.4 LTS上通过NTLM身份验证安装了Squid 2.7。在客户端，我使用Windows 7 Professional（配置了Ubuntu服务器的NTLM代理）。
但是当它在我的Internet Explorer浏览器中呈现时，它在/var/log/squid/access.log中显示407代码，并不断弹出身份验证框，并且没有重定向到我希望的URL。同样，当我使用WinHTTP以编程方式对C ++代码执行相同的操作时，它也会返回400错误请求。
Access.log在从浏览器访问时说：1566392960.125 1 172.16.xx.xx1 TCP_DENIED/407 1541 GET http://172.16.xx.xx2/ - NONE/- text/html
而172.16.xx.xx1是代理服务器，而http://172.16.xx.xx2/本地http服务器我希望它进行重定向。
以下是我的squid.conf设置：

它应通过ntlm代理进行身份验证，并应重定向到已定义的url。
