PowerScale：AD sudo 命令在升级后停止工作

“系统管理员”角色中的 Active Directory 用户（在此例中 AD 用户名为“PowerScale”）仍允许进入 SSH，命令失败，如下所示：

cluster-1# ssh DOMAIN\\PowerScale@cluster-1
(DOMAIN\PowerScale@cluster-1) Password: 
PowerScale OneFS 9.12.0.1
Could not chdir to home directory /ifs/home/DOMAIN/PowerScale: No such file or directory
cluster-1% sudo -s

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

For security reasons, the password you type will not be visible.

Password: 
Sorry, try again.
Password: 
Sorry, try again.
Password: 
sudo: 3 incorrect password attempts

错误 /var/log/auth.log 类似于：

2026-01-09T14:08:46.964341-05:00 <4.6> isi-9510-1(id1) sshd[9292]: Accepted keyboard-interactive/pam for DOMAIN\PowerScale from 10.20.48.1 port 31599 ssh2

sudo 更新导致大写的 Active Directory 用户名失败。请注意，这仅适用于需要 Active Directory 用户获得密码提示的环境，无密码 sudo 命令应该不受影响。受密码保护的提示在 'isi_visudo' 喜欢这个：

DOMAIN\\powerscale ALL=(ALL) PASSWD: ALL

PowerScale 工程部门已发现此问题，并正在开发永久修复方法。用户可以编辑 Active Directory 中的用户名，使其全部小写：

与任何 Active Directory 编辑一样，可能需要一些时间才能传播。如果用户仍无法正常工作，请启动日志收集并联系 PowerScale 支持。
