BadCredentialsException:Kerberos验证未成功

本文介绍了BadCredentialsException:Kerberos验证未成功的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我想通过SPNEGO执行身份验证.我使用:

I would like to perform authentification with SPNEGO. I use:

  • spring-core-3.1.0.RELEASE.jar
  • spring-security-core-3.1.0.RELEASE.jar
  • spring-security-kerberos-core-1.0.0.M2.jar
    • 来自Spring的
  • 包编解码器核心安全性3.0.7(https://jira.springsource.org/browse/SES-98)
  • tomcat
  • spring-core-3.1.0.RELEASE.jar
  • spring-security-core-3.1.0.RELEASE.jar
  • spring-security-kerberos-core-1.0.0.M2.jar
  • package codec from springcore security 3.0.7 (https://jira.springsource.org/browse/SES-98)
  • tomcat

我的配置文件如下所示.当我尝试对上述库进行身份验证时，出现以下异常.

My Config file looks like the following. When I try to authentificate with the above libraries I got the following exception.

有人遇到了同样的问题并解决了吗?

Had someone the same problem and handled it?

配置文件(摘自Spring Security kerberos示例):

推荐答案

我发现了问题.Spring-security-kerbos要求密钥表文件的路径为"Resource String"(详细信息: http://static.springsource.org/spring/docs/3.0.x/reference/resources.html ).当我将路径设置为"file:/home/xxxxx/conf/krb5/krb5.keytab"时，应用程序运行，但我认为它以后无法打开文件，并且Kerberos无法加载任何密钥.不幸的是，来自Kerberos的日志不是很清楚.

I found the problem.Spring-security-kerbos requires path to keytab file as "Resource String" (details: http://static.springsource.org/spring/docs/3.0.x/reference/resources.html).When I set path as "file:/home/xxxxx/conf/krb5/krb5.keytab" then application runs but I think that it can't open the file later and Kerberos cant load any key. Unfortunately Log from Kerberos is not so clear.

当我将路径设置为"/home/xxxxx/conf/krb5/krb5.keytab"时，出现以下异常

When I set path as "/home/xxxxx/conf/krb5/krb5.keytab" I got the following exception

Caused by: java.io.FileNotFoundException: ServletContext resource [/home/xxxxx/conf/krb5/krb5.keytab] cannot be resolved to URL because it does not exist

此问题的解决方案可以是文件SunJaasKerberosTicketValidator.java中的修复程序:

Solution for this issue can be the fix in the file SunJaasKerberosTicketValidator.java:

private String keyTabLocation;

LoginConfig loginConfig = new LoginConfig(keyTabLocation, servicePrincipal, debug);

代替:

private Resource keyTabLocation;

LoginConfig loginConfig = new LoginConfig(keyTabLocation.getURL().toExternalForm(), servicePrincipal, debug);

使用此修复程序，一切正常.我们可以将文件路径设置为"/home/xxxxx/conf/krb5/krb5.keytab"

With this fix everything works. We can set path to file in format "/home/xxxxx/conf/krb5/krb5.keytab"

如果有人知道更多详细信息，请在此处写下.
