Symptoms

處於「系統管理員」角色的 Active Directory 使用者 （在此情況下，AD 使用者名稱為「PowerScale」） 仍允許 SSH 進入，命令失敗，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
cluster0-1%

錯誤 /var/log/auth.log 類似於：

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
2026-01-09T14:09:02.165862-05:00 <4.1> isi-9510-1(id1) sudo[9315]: DOMAIN\PowerScale : 3 incorrect password attempts ; TTY=pts/1 ; PWD=/ ; USER=root ; COMMAND=/bin/zs

Cause

sudo 的更新導致大寫的 Active Directory 使用者名稱失敗。請注意，這僅適用於需要 Active Directory 使用者取得輸入密碼提示的環境，無密碼 sudo 命令應不會受到影響。受密碼保護的提示在 'isi_visudo' 像這樣：

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

Resolution

PowerScale 工程部門已發現此問題，並正在努力制定永久修正方法。使用者可以在 Active Directory 中編輯使用者名稱，使其全部為小寫：

與任何 Active Directory 編輯一樣，可能需要一些時間才能傳播。如果使用者仍無法正常運作，請啟動記錄收集，並聯絡 PowerScale 支援。
