Folder permissions - Traversing folders to only access subfolders, multiple users

I need to setup folder permissions to an existing directory structure in a domain.

I have 4 groups of users that need access to certain subfolders on a shared drive, but should not have access to any files in any folders above those subfolders

ie: \\Server\Shares\ENG\ENG-Draw\ENG-Part

all users have a drive mapping s: to \\Server \Shares

How can I set up permissions to allow group1 access to s:\ENG\ENG-Draw\ENG-Part dir only?

I've read about the Traverse directory permission, but have never implemented it.

Any direction here is appreciated.

You need to remove the Inheritable permissions on the folder

Do the following...
- nav to that folder (s:\ENG\ENG-Draw\ENG-Part)
- Right click, Properties
- Click Security Tab
- Click Advance button
- Click Change permissions button
- remove the check mark for "include inheritable permissions from this objects parent"
- Click the Add button ( this will allow you to add to this current list of users that have already been populated)
- Click Add button and add Group1
- Set the permissions for Group1

In your case 1st thing to do:

Ensure that share root has "authenticated users" have full control share permissions
disable permissions inheritance on root share folder advanced NTFS permissions with convert explicit option
Then grant "authenticated users" List folder contents permissions on root share
Remove any explicit groups if defined here on ACL

Now go to "Eng-Part" folder and disable inheritance and change authenticated users permissions scope (Applied to) to this Folder Only
Then add required group required access here

This process to followed for all other groups

This will ensure that group members will able to access only folders for which they have access
Also you may enable access based enumeration on share folder so that folders get hide from explorer for which user do not have permissions

Thanks for the responses.

There are about 10 other dirs under Shares, (Sales, Prod, Quality, etc.) and then several under each one of them.

If I give full share permissions, and disable inheritance, I will have to assign/remove NTFS permissions manually to every subfolder, and then manually to every subfolder's subfolder.

ie Managers need full access to all folders, and the same groups may need access to other specific directories within the structure.

Assigning permissions manually will be a headache especially if a new folder is created.

Is there any other way?

Are you familiar with implementing the Traversal permission?

Thanks again,

You leave Share permissions for Everyone to Full. You then only modify Security Permissions for Security only. depending on how granular you want to have this you will need to do this manually. The other option would be to create new Shares and apply permissions accordingly for each  security groups.

Its not required, by disabling inheritance, you don't have to set permissions manually on sub folders
Sub folders still will get inherited permissions from root share

If manager group require full permissions, you can grant them Modify \ full NTFS permissions on folder root once, it will get propagated to all sub folders

I have asked you to disable inheritance on share root because it is best practice and only way to stop flowing drive level permissions on root share
Whatever explicit permissions you will apply on root share will not affected by disabling inheritance.

Check below article for best practices to setup share folders

Thanks both of you for your quick responses.

I was able to get the permissions functioning the way I needed by blocking inheritance, converting and editing NTFS permissions on the folders and sub folders accordingly.

Thanks again for pointing me in the right direction.
