为什么 Kerberos/SPNEGO 身份验证不起作用？

Question

I' 使用 Vaadin 框架开发 Java Web 应用程序。我想在不提示输入用户名和密码的情况下对用户进行身份验证。为此，我想实现Kerberos/SPNEGO来在我的Java代码中注入这些东西。 我所需要的只是拥有连接到Web应用程序的用户的域用户名。

我按照网站上的说明进行操作：https://tomcat.apache.org/tomcat-9.0-doc/windows-auth-howto.html

然后我做了这里描述的所有内容：http://spnego.sourceforge.net/troubleshoot_hellokeytab.html

现在我有工作 HelloKDC 返回我：

Postdated Ticket false
Renewable Ticket false
Initial Ticket false
Auth Time = Tue Jun 18 11:25:22 CEST 2019
Start Time = Tue Jun 18 11:25:22 CEST 2019
End Time = Tue Jun 18 21:25:22 CEST 2019
Renew Till = null
Client Addresses  Null 
Private Credential: C:tomcat.keytab for 
HTTP/[e-mail]
Connection test successful.

密钥表是使用以下方法生成的：

ktpass -out c:tomcat.keytab /princ 
HTTP/[e-mail] /pass myPass! 
/mapuser serviceUser /crypto AES256-SHA1 /ptype KRB5_NT_PRINCIPAL

请记住，该应用程序服务器位于 myserver 中。EU.CORP.MYCOMPANY.NET，而用户来自 CORP.MYCOMPANY.NET 域。

protected void init(VaadinRequest request) {  
    System.out.println("5 " + request.getRemoteUser());
}

返回空值。

似乎没有适当的身份验证。我做错了什么？

经过多天的寻找选择，我找到了适合我的情况的解决方案。

似乎我的过滤器仅适用于*.jsp应用程序。我刚刚改变了：

<filter-mapping>
  <filter-name>SpnegoHttpFilter</filter-name>
  <url-pattern>*.jsp</url-pattern>
</filter-mapping>

为：

<filter-mapping>
  <filter-name>SpnegoHttpFilter</filter-name>
  <url-pattern>*</url-pattern>
</filter-mapping>

它解决了我的问题，也许它会帮助某人。
