Java Kerberos身份验证似乎起作用了，但仍然被拒绝。

I've got a Java client app and a Java server app, and I'm trying to authenticate to the server via Kerberos. The client basically uses http-components and SPNEGO to make a HTTP GET call, but I always get 401 Unauthorized as a result.

我有一个Java客户机应用程序和一个Java服务器应用程序，我正在尝试通过Kerberos对服务器进行身份验证。客户端主要使用HTTP -组件和SPNEGO进行HTTP GET调用，但我总是得到401未经授权的结果。

I can not spot the error in the Kerberos login sequence below, maybe you guys can:

我不能在以下的Kerberos登录序列中发现错误，也许你们可以:

2 个解决方案

#1

What library do you use on the server side? Did you enable debug flags to see what happens when the server processes the service ticket?

你在服务器端使用什么库?您是否启用调试标志来查看当服务器处理服务票据时发生了什么?

#2

Your Kerberos configuration might be completely fine. The 401 messsage means that the authentication itself probably went fine. However, i suspect the webapp only allows users if they are assigned a Role. The SPNego mechanism does not assign such role out-of-the-box. You still need to configure a Realm that performs the mapping.

您的Kerberos配置可能完全没问题。401 messsage意味着认证本身很可能已经很好了。但是，我怀疑这个webapp只允许用户被分配一个角色。SPNego机制没有将这种角色分配到开箱即用。您仍然需要配置一个执行映射的领域。
