The problem is that smb setup is not consistent. From one hand you get this mantra “look how easy it is” - which is an lie. What actually should happen is:

1. creating an share should check if we also need to do smbadm join domain or workgroup; if its workgroup, then the join should also set up the pam entry.
2. Set up the default ACL for share. This one is major pain, it is not properly documented, the current default is useless and confusing.
3. create /etc/avahi/services/smb.service for SMB.

Also note that if you need to read wiki just to set up the SMB share, it means the whole concept is already wrong - it has nothing to do with being simple nor easy nor user frendly.
