Cause

建立的 PowerProtect 認證包含無效的使用者名稱或密碼。建立 PowerProtect 認證不會執行驗證檢查，因此在進行驗證之前不會出現症狀。使用者名稱可以「domain\username」格式或「username@domain.suffix」格式列出。使用 username@domain 格式時，必須指定網域尾碼 （.org、.com、.edu）。

有效使用者名稱的範例：

administrator@my-domain.com
my-domain\administrator

無效使用者名稱的範例：

administrator@my-domain
administrator

Resolution

更新 PowerProtect 登入資料，以反映正確的使用者名稱格式並包含正確的密碼。

  1. 在 PowerProtect 中，按一下 管理 > 認證。
  2. 選取認證，然後按一下 編輯。
  3. 輸入正確的使用者名稱和密碼。
  4. 按一下儲存。
