Question

我尝试使用Kerberos连接数据库，除了两个问题外，一切正常。首先，当我执行我的代码时，我被要求两个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。

上述问题源于我相信根本原因，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;
};

我知道我还没有禁用键盘输入，但这是因为从上面的输出中可以看出我无法读取密钥表或缓存。

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

我甚至为chmod 777做了keytab，以确保这不是一个权限问题。

Answer 1

这是权限问题，我无法读取/ tmp

下的缓存文件

GSS JAAS无法读取密钥库/标签
