Cause

sysadmin 帐户是唯一可以在 Data Domain 中注册 SSO 的帐户。

在这种情况下，您会收到管理员凭据要求错误。在 DPC 中以 sysadmin 以外的用户身份发现 Data Domain，这导致此作失败。

Resolution

在日志中，您会看到以下导致注册失败的凭据错误：

Caused by: com.emc.clp.spi.ForbiddenException: Administrator credentials required for the SSO registration
  • 要向 SSO 注册，您必须使用 sysadmin 帐户，因为这是唯一可以注册 SSO 的帐户。即使是其他管理员帐户也没有该权限。 
  • 在 DPC 中发现 Data Domain 时，可能尚未为其提供 sysadmin 帐户。在 DPC 系统管理页面中编辑 Data Domain，然后输入 sysadmin 帐户和该帐户的密码。 
  • 尝试从 DPC UI 再次注册 SSO。
注册应成功。
