答案: 问题是针对此类问题的所有帖子都与较旧的 kerberos 和 IIS 问题有关，其中代理凭据或AllowNTLM 属性有帮助.我的情况不同.经过数小时从地面挑选蠕虫病毒后，我发现有些 IIS 安装在 IIS Windows 身份验证提供程序列表下没有包括 协商提供程序.所以我不得不添加它并向上移动.我的 WCF 服务开始按预期进行身份验证.这是屏幕截图，如果您使用 Windows 身份验证并关闭匿名身份验证.

THE ANSWER: The problem was all of the posts for such an issue were related to older kerberos and IIS issues where proxy credentials or AllowNTLM properties were helping. My case was different. What I have discovered after hours of picking worms from the ground was that somewhat IIS installation did not include Negotiate provider under IIS Windows authentication providers list. So I had to add it and move up. My WCF service started to authenticate as expected. Here is the screenshot how it should look if you are using Windows authentication with Anonymous auth OFF.

您需要右键单击 Windows 身份验证并选择提供程序菜单项.

You need to right click on Windows authentication and choose providers menu item.

希望这有助于节省一些时间.

Hope this helps to save some time.
