Symptoms
- 失敗的驗證嘗試次數:使用者無法使用 LDAP 登入資料在 PowerFlex 中進行驗證。
- 直接 AD 認證沒有問題:使用者或許能夠直接使用 Active Directory 進行驗證,不會發生任何問題,但是當他們透過 PowerFlex 使用 LDAP 時,就會出現此問題。
主要 MDM (PMDM) trc 記錄會顯示類似輸出,如下所示:

Cause
使用 PowerFlex 進行 LDAP 驗證時,第三方平衡器可能會阻礙 LDAP 流量。
Resolution
可能的因應措施是在使用 SCLI 建立 LADP 服務時,將 LDAP 認證直接指向網域控制站。通過這樣做,您可以繞過第三方均衡器導致的任何潛在阻塞或問題。
您必須刪除並重新建立 LDAP 服務,才能使用 SCLI 將其直接指向網域控制站。
