GSS JAAS 无法读取 keystore/tab

Question

我正在尝试使用 Kerberos 连接到数据库，除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而不是一次。然后我的查询被发送到我的数据库并返回结果。

以上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 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，我无法读取密钥表或缓存。

服务器和客户端都匹配 krb5.conf，我能够 kinit、ktadd、klist 都期望具有正确 enc 类型的主体。

我什至对 keytab 进行了 chmod 777，只是为了确保这不是权限问题。

Answer 1

这是一个权限问题，我无法读取 /tmp 下的缓存文件
