问题

在部署ansible到新环境的时候，配置完成后发现管理windows机器，运行时出现问题找不到Server
运行命令

kinit xxx@DOMAIN.LOCAL

能够正常返回，说明kerberos没有问题
运行命令

ansible windows -m win_ping -vvvvv

返回错误：

'Server not found in Kerberos database'.
     ansible windows -m win_ping -vvvvv

检查

执行命令

  host winmachine.domain.local

可以解析到IP xxx.xxx.xxx.xxx
将上一步得到的IP做反向查找

 host xxx.xxx.xxx.xxx

得到的是一个错误记录 promote.cache-dns.local
由此看来是DNS解析有问题

修复

到AD上，打开DNS服务，果然没有建反向解析区域，新建反向解析区域并添加对应windows机器的解析记录，问题解决。
