Why? Because members who are part of the group that is being re-used will suddenly have more permissions than the group name would indicate. They do this because they don’t know any better, but the results are just as fatal. However, it is better not to assign rights to organizational groups directly, but instead to use them solely to group together users belonging to the same organizational unit.įinally, in order to then grant all users of an organizational unit certain permissions, the organizational group must become a member of the appropriate read or write group for the directory.Įven admins who follow these recommendations and set NTFS permissions via group membership, tend to fall for another common mistake : admins reusing groups to assign permissions, without being aware of what the permission group was originally intended for. giving them direct NTFS permissions to certain folders.

One common but detrimental practice is using organizational groups as permission groups (especially on department drives), i.e. Using Organizational Units as Permission Groups

The ACE is used on directories if users are given access rights directly. This is because removing a user from AD will delete the user account itself (including all group memberships), but not its ACEs, or Access Control Entries. If the user is deleted at some point later on, what we are left with is a so-called orphaned SID (recognizable by its infamous “unknown account” entries (S-123-12345-12345). If the user is given access directly, the permission entry will not appear in that person’s user account, which in turn has a very negative impact on transparency. The number 1 mistake made when setting NTFS permissions is giving user objects direct access to folders instead of using groups (where the user is a member of Group X and Group X is given access to the folder). The 5 Most Common Mistakes When Setting NTFS Permissions 1. To set NTFS permissions, right-click on a folder or file and select “Properties”, then go to the “Security” tab to select permissions. To learn more about the difference between share permissions and NTFS permissions, click here. In contrast to share permissions, where the choice of permission levels is limited to “Read”, “Modify” or “Full Control”, NTFS permissions give you more granular control. NTFS permissions allow you to grant directory access to individual users and groups.
