华为的Kafka kerbro认证，报This may indicate that authentication failed due to invalid credentials

对接kakfa kerbro认证报

Connection to node -1 terminated during authentication. This may indicate that authentication failed due to invalid credentials.

一般是什么原因？

文件路径核对过了是正确的，用命令kinit去认证的话可以成功，到java程序里面就不行了

是因为本地时间和认证服务器时间对不上吗？

首先，你先用命令行进行生产和消费，确认下是否一切正常：kafka实战kerberos（笔记）

其次，当你java程序连接集群的时候，你观察下kafka打印的日志。

另外，你需要补充一下java认证的部分代码，看看你是如何设置认证的。

这个是启动前初始化设置设置认证文件

去kafka集群，看看日志。

亮闪闪 -> 半兽人 2年前

kafka是华为那边的，好像拿不到这个日志，我这边Linux服务器上klist可以看到信息，应该是服务器上已经认证成功了，在windows系统上的程序也能成功生产信息发送过去，目前就是在Linux上跑的程序一直报这个错误

半兽人 -> 亮闪闪 2年前

那基本可以聚焦是证书路径的问题了，你先写成绝对路径看看。

亮闪闪 -> 半兽人 1年前

目前写的是绝对路径

/opt/opsmgr/web/components/lcresort.1/bin/lcresort-web/config/krb/user.keytab

核对几次了，是没问题的。

亮闪闪 -> 亮闪闪 1年前

jaas的路径是

/opt/opsmgr/web/components/lcresort.1/bin/lcresort-web/temp/root.jaas.conf
