红帽全球峰会9.5. 验证 Kerberos 配置
要验证 Kerberos 配置，请测试是否可以获取身份管理(IdM)用户的单子，以及 IdM 用户是否可以请求服务单。
流程
为 Active Directory（AD）用户请求一个 ticket（票据）：
kinit user@AD.EXAMPLE.COM
[root@ipaserver ~]# kinit user@AD.EXAMPLE.COMCopy to Clipboard Copied! Toggle word wrap Toggle overflow 为 IdM 域中的服务请求 ticket：
kvno -S host server.idm.example.com
[root@server ~]# kvno -S host server.idm.example.comCopy to Clipboard Copied! Toggle word wrap Toggle overflow 如果 AD 服务单被成功授予了，则会列出一个跨领域单据授予单（TGT），以及所有其他请求的单子。TGT 命名为 krbtgt/IPA.DOMAIN@AD.DOMAIN。
localauth 插件将 Kerberos 主体映射到本地系统安全服务守护进程(SSSD)用户名。这允许 AD 用户使用 Kerberos 身份验证并访问 Linux 服务，这些服务直接支持 GSSAPI 身份验证。
