Hi,
This is a Synology configuration issue. Please do the following:
Go to Control Panel > Shared Folder.
Select the shared folder whose permissions you wish to edit. Click Edit.
Go to the Permissions tab.
Select the following from the drop-down menu:
System internal user: Assign permissions for default system users, such as the Anonymous FTP/WebDAV user. Before allowing anonymous FTP users to connect to a shared folder, you need to assign access permissions for this user.
Tick or untick the appropriate boxes for each user or group to customize their access permissions for the shared folder:
Read/Write: The user or group can access and make changes to the files and subfolders in the shared folder.
Read only: The user or group can access the files and subfolders in the shared folder.
No access: The user or group cannot access the files or subfolders in the shared folder.
Click OK to finish.
I hope this answers your question.
