我正在现有的 java spring 应用程序中实现 kerberos 身份验证。我的 unix 团队为我提供了 SPN、krb5.conf 和 keytab 文件。我正在努力使用下面的代码和配置，但无法从用户异常中获取密码，如下面附加的日志所示。
如果我做错了什么或者可能出了什么问题，有人可以纠正我吗？如果您需要更多这方面的信息，请告诉我。
如果有人能告诉，如何验证 kerberos 配置是否正确，那就太好了？
这是我尝试过的。我正在使用：

这可能是由于安全配置上的属性值未解析。您可以硬编码以下内容并重试吗？
<beans:property name="servicePrincipal" value="HTTP/[email protected]"/>
<beans:property name="keyTabLocation" value="file:YOUR KEY TAB LOCATION >>/mykey.keytabl" />
您的错误是从 javax.security.auth.login.LoginContext 的 init 方法引发的，因此应该与 keytab 文件或服务原理设置不正确有关。
感谢您的回复。我已经解决了这个问题，问题是我的密钥表。我的密钥表文件不包含我正在寻找的 SPN。它是使用错误的 SPN 生成的。我尝试使用一些虚拟 SPN，发现遇到了相同的异常，然后要求团队验证或生成新的密钥表。
这个总是让我抓狂，因为它是一种通用/只有半有用的错误，而且它经常发生。这次我通过转义 krb5.conf 文件路径中的反斜杠解决了这个问题。
一年后同样的问题。这次是以 64 为基础编码的密钥表错误。
