Guest on Public Folder Not Working

[spoiler]

I'm brand new to TOS and TNAS so I'm probably doing something fundamentally wrong here but I can't see what it is.

With my WD NAS I can navigate around the public folders just fine without having to log in or anything and that's the behaviour I'm expected to see with the TNAS too.

With the TNAS (423, TOS 6.0.577-00166) I have a shared public folder on Volume2 and guest has read / write permissions. In the Mac Finder I can see the TNAS in the Network location but I can't connect to it. I just get a "Connection Failed" message in the Finder.

I can connect as the admin user and as a normal user but to do that I have to actively connect as that user so I guess it's a guest account thing. I'm thinking the guest account should just work and let me navigate around the public folder without having to log on.

What am I doing wrong? How can I make the guest account work properly with the public folder?

Guest account is disabled by default. so you need to enable the guest account, control panel > user > edit > advanced settings
Then grand the public folder guest permission, control panel > shared folder > public > edit > permissions

I figured that bit out.

The guest account has been enabled and appears to be working:



It looks like the folder has the correct user permissions applied to it:



and group permissions too



That's why I think I'm missing something. I think I've made all the obvious changes but it looks like I've missed something because it just doesn't work.

After changing permissions, please restart the SMB service.

I have to admit, I didn't think of trying that. I might have done it while I was poking around with things but I don't remember explicitly restarting the SMB service.

So, in the absence of a "restart" button, I unchecked the service, applied the change, rechecked the service and applied the change again to no effect.

The finder still fails to connect.

When the service is disabled the TNAS no longer appears in the Finder, so I know the stop worked.

This is what the SMB config looks like:



I haven't touched the Advanced config at all.

I enabled "Collect debug log" and here's a snippet that *might* be useful:

It looks like the system is trying to authenticate the guest user and failing.

Any ideas on how to fix this?
