java - 为什么 Kerberos/SPNEGO 身份验证不起作用？

Question

我正在使用 Vaadin 框架开发 Java 网络应用程序。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 以将这些内容注入(inject)我的 Java 代码中。 我只需要有连接到 webApplication 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事情:http://spnego.sourceforge.net/troubleshoot_hellokeytab.html

现在我有工作的 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/myserver.eu.corp.mycompany.net@EU.CORP.MYCOMPANY.NET
Connection test successful.

key 表是使用以下方法生成的:

ktpass -out c:\tomcat.keytab /princ 
HTTP/myserver.eu.corp.mycompany.net@EU.CORP.MYCOMPANY.NET /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.EU.CORP.MYCOMPANY.NET 中，而用户来自 CORP.MYCOMPANY.NET 域。

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

返回空值。

似乎没有正确的身份验证。我做错了什么？

Answer 1

经过多日的寻找选择，我找到了解决我的案例的办法。

我的过滤器似乎只适用于 *.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>

对于:

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

它解决了我的问题，也许它会对某人有所帮助。
