红帽全球峰会5.3. 更新受管服务帐户的密码
系统服务安全守护进程(SSSD)自动为受管服务帐户进行常规密码轮转。管理员可以运行 adcli 来手动刷新凭证，确保本地 keytab 与 Active Directory 更改保持同步。
先决条件
- 您之前为 production.example.com AD 域中的主机创建了 MSA。
-
可选：您已安装了
krb5-workstation软件包，其包括klist诊断工具。
流程
可选：显示 Kerberos keytab 中 MSA 的当前密钥版本号(KVNO)。当前 KVNO 是 2.
[root@client ~]# klist -k /etc/krb5.keytab.production.example.comKeytab name: FILE:/etc/krb5.keytab.production.example.com KVNO Principal ---- ------------------------------------------------------------ 2 CLIENT!S3A$@PRODUCTION.EXAMPLE.COM (aes256-cts-hmac-sha1-96) 2 CLIENT!S3A$@PRODUCTION.EXAMPLE.COM (aes128-cts-hmac-sha1-96)更新
production.example.comAD 域中 MSA 的密码。[root@client ~]# adcli update --domain=production.example.com --host-keytab=/etc/krb5.keytab.production.example.com --computer-password-lifetime=0
验证
验证在 Kerberos keytab 中已递增了 KVNO：
[root@client ~]# klist -k /etc/krb5.keytab.production.example.comKeytab name: FILE:/etc/krb5.keytab.production.example.com KVNO Principal ---- ------------------------------------------------------------ 3 CLIENT!S3A$@PRODUCTION.EXAMPLE.COM (aes256-cts-hmac-sha1-96) 3 CLIENT!S3A$@PRODUCTION.EXAMPLE.COM (aes128-cts-hmac-sha1-96)
