Cause

PowerProtect 凭据创建包含无效的用户名或密码。PowerProtect 凭据创建不会运行身份验证检查，因此在进行身份验证之前不会出现该症状。用户名可以以“域\用户名”格式或“username@domain.suffix”格式列出。使用username@domain格式时，必须指定域后缀（.org、.com、.edu）。

有效用户名示例：

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

无效用户名的示例：

administrator@my-domain
administrator

Resolution

更新 PowerProtect 凭据以反映正确的用户名格式并包含正确的密码。

  1. 在 PowerProtect 中，单击 AdministrationCredentials>。 
  2. 选择凭据，然后单击 编辑。
  3. 输入正确的用户名和密码。
  4. 单击 Save。
