适用场景

  • ONTAP 9
  • Data ONTAP 8 7-模式

问题解答

  • 在CIFS共享上启用基于访问的枚举(ABE)后、无权访问其下的文件夹或文件的用户 将无法 在其环境中看到这些信息。
    • 文件和文件夹的实际权限不会更改、只有可见性会更改。
    • Abe不会隐藏共享本身、它仅会根据访问权限隐藏在其下创建的文件夹/文件。​​
    • 如果用户或自动化系统出于索引编制或管理目的而依赖于所有文件和文件夹的可见性、则ABE可能会中断这些操作。

注意: 每个SVM没有全局选项、如果需要、每个共享必须启用ABE

  • 本地管理员仍具有无限制枚举
    • BUILTIIN\Administrators组的成员将 被授予对本地系统的无限制访问权限
    • 因此、此组中的帐户可以枚举整个目录
  • 默认情况下、ABE处于禁用状态
  • 启用ABE
    • 适用于Data ONTAP 8 7-模式
      • cifs shares -change sharename -accessbasedenum
    • 适用于ONTAP  9
      • ::> cifs share properties add -vserver <vserver> -share-name <share> -share-properties access-based-enumeration
  • 禁用 ABE
    • 适用于Data ONTAP 8 7-模式
      • cifs shares -change sharename -noaccessbasedenum
    • 适用于ONTAP  9
      • ::> cifs share properties remove -vserver <vserver> -share-name <share> -share-properties access-based-enumeration
