ACL Problem

I want to define ACL on a share named share01 for User1, User2 & User3.

User1 has Read, Write, Execute & delete.
User2 has Write only, cannot delete.
User3 has Read only.

I have try to set ACL, but unable to do that. Please guide me very step-by-step.

This is located in the GUI from CONFIGURATION -> NAS resources -> Function: ACL (Access control list).

Then select the Logical Volume that the Share is on then select the Users and Groups Tab then select the Access Permissions Tab. Function for ACL details are below.

Function: ACL (Access control list)

With this function you can assign ACL permissions to your folders or files.

Browser

Filter
Shows only folders or files with a given name.
Selection
Shows where you are in the directory's browser.

Users & Groups

Available Users & Groups
List of available users and groups which can have access permissions assigned to them.
Selected Users & Groups
List of selected users and groups which will have access permissions assigned to them.

Access Permissions

Recursive
If this option is checked the ACL permissions will be assigned to all folders and files within the selected folder.
Set owner
If this option is selected the designated user(s) or group(s) will be owner(s) of the selected folders or files.
Access Permissions

* read
* write
* execute (for folders, this means the permission to open, while for files, the permission to execute)

In order to assign ACL permissions:

* select a folder or a file,
* click the Users & Groups tab,
* select which users or groups will be assigned access permissions,
* click the Access Permissions tab,
* select user ([U]) or group ([G]) or User(owner) or Group(owner),
* check the appropriate boxes under Access Permissions,
* click Apply.

Examples:

Example 1.

This example presents a situation in which User1 has read access permissions for directory A only and does not have access permissions for subdirectory B at all.

A User1 r-x
B User1 ---

Example 2.

User1 has access permission only for reading for directory A. Can enter sub directory B, but no files are visible.

A User1 r-x
B User1 --x

Example 3.

User1 can enter the subdirectory C and can read and write files within that subdirectory.

A User1 r-x
B User1 --x
C User1 rwx
Note

Designating the user as a superuser within the SMB settings function will automatically assign all access permissions to that user.

Assigned access permissions will be available under sFTP, FTP and SMB network protocols.

User(owner) or Group(owner) can also have access permissions assigned. These permissions may be different from the ones assigned to the same user in the Users/Groups list.
