The folder is shared with no restrictions. I have 2 drives in a RAID 1. So I have only Volume_1. Only a folder inside Volume_1 named "Data" is shared. I have usernames and passwords for two users who can use access them. But if I choose all accounts to be able to access the "Data" folder, then even "Data" is accessible with no restrictions.
I assume that if "Data" folder is set to be a samba share for all accounts, it should be accessible for all usernames only. But what I see is that "Data" is accessible without even asking for username & password.
I have fun_plug installed. So I have a "sshd" as a third user.
