GSS JAAS 无法读取密钥库/选项卡

【中文标题】GSS JAAS 无法读取密钥库/选项卡

【英文标题】：GSS JAAS can't read keystore/tab

【问题描述】：

我正在尝试使用 Kerberos 连接到数据库，除了两个问题外，一切正常。首先，当我执行我的代码时，我被要求两次输入我的密码，不是一次而是两次。然后我的查询被发送到我的数据库并返回结果。

上述问题源于我认为的根本原因，或者我遇到的第二个问题是，我的 JDK 无法读取密钥表。

com.sun.security.jgss.initiate 
    com.sun.security.auth.module.Krb5LoginModule required
    useKeyTab=true
    useTicketCache=true
    principal="principal@REALM"
    useDefaultCcache=true
;

com.sun.security.jgss.accept  
  com.sun.security.auth.module.Krb5LoginModule required
  ticketCache=true
  storeKey=true;
;

我知道我没有禁用键盘输入，但这是因为正如您从上面的输出中看到的那样，我无法读取 keytab 或缓存。

服务器和客户端都有匹配的 krb5.conf，我可以 kinit、ktadd、klist 所有期望具有正确 enc 类型的主体。

我什至对 keytab 进行了 chmod 777 以确保这不是权限问题。

【参考方案1】：

这是权限问题，我无法读取 /tmp 下的缓存文件
