How Add Group To A Samba Share

sudo groupadd samba sudo usermod -g samba myuser sudo usermod -g samba guest sudo chmod 770 /mnt/shared_files/ In smb.conf, we need: valid users = @samba Like so:

[backup_shared_files]
path = /mnt/shared_files
valid users = @samba
browsable = yes
writable = yes
read only = no
guest ok = yes

sudo systemctl restart smb; sudo systemctl restart nmb
