How to apply NTFS permissions on a directory where inherited and non-inherited permissions differ for the same user or group

Last Updated:

Applies to




  • This process is not the recommended method for NTFS ACL management.
  • It is recommended to use the Windows 'Security' tab whenever possible.
  • NTFS ACLs permissions can be applied to these objects:
    • Current Folder
    • Subfolders
    • Files
  • You can apply NTFS ACLs to all three, however it is not possible to apply different sets of permissions for the same user
For example:
vserver security file-directory ntfs dacl add -ntfs-sd <SD-Name> -vserver <vServer-Name> -access-type allow -account "Domain\User_or_Group" -rights modify -apply-to sub-folders,files
  • The first command was successful
vserver security file-directory ntfs dacl add -ntfs-sd <SD-Name> -vserver <vServer-Name> -access-type allow -account "Domain\User_or_Group" -rights read -apply-to this-folder
  • The Second command failed with the following error string: error: command failed: duplicate entry
    • The reason for the error is that you cannot add 2 different set of permissions in 1 Security Descriptor (SD) to the same object (user\group).
  • This ability exists from the Windows side in case of a need: Security Tab > Advanced
