- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我正在尝试在kubernetes下的linux docker容器中使用Windows身份验证。
我正在执行以下设置:https://docs.microsoft.com/en-us/aspnet/core/security/authentication/windowsauth?view=aspnetcore-3.1&tabs=visual-studio#kestrel
应用程序位于.net core3中,具有nuget Microsoft.AspNetCore.Authentication.Negotiate并在kestrel中运行
我已经添加了
services.AddAuthentication(Microsoft.AspNetCore.Authentication.Negotiate.NegotiateDefaults.AuthenticationScheme).AddNegotiate();
app.UseAuthentication();

本文是误解事物运作方式的一个很好的例子。我完全不建议遵循本文所述的方式(像我一样)。
相反,我建议您学习Kerberos身份验证,其工作方式,所需的设置。这个article形象地很好。
首先,
如果您分析来自浏览器(例如,用户Fiddler)的HTTP流量,则可以在第二个请求中找到TGS token 。
TlR
开头,那么您正在通过NTLM进行身份验证。 YII
开头,那么您正在通过Kerberos进行身份验证。 TlR
token 和
ntlm-gssapi
机制,则将获得
“未提供凭据,或者凭据不可用或不可访问。” 错误。
TlR
token 并使用默认的Kerberos机制,则将获得
“请求了不受支持的机制”。
MYDOMAIN.COM
webapp.webservicedomain.com
的Web应用程序。这可以以mydomain.com
结尾,但就我而言不是。 mymachine
的名称加入了AD。 MYDOMAIN\mymachine
setspn -S HTTP/webapp.webservicedomain.com mymachine
setspn -S HTTP/webapp@MYDOMAIN.COM mymachine
ktpass -princ HTTP/webapp.webservicedomain.com@MYDOMAIN.COM -pass myKeyTabFilePassword -mapuser MYDOMAIN\mymachine$ -pType KRB5_NT_PRINCIPAL -out c:\temp\mymachine.HTTP.keytab -crypto AES256-SHA1
*。 MYDOMAIN\mymachine
允许在AD中使用
AES256-SHA1
。
