#38409 — Share authentication failure

I have little experience with networked file sharing, such as using old 
Wins such as XP and W7.

Phase I

Desktop, bios '11, 8G ram, AMD Athlon II, SSD Ventoy/ed, booting live 
Linux Mint Cinn 23. Install Webmin & samba, use its network samba 
function to share a connected USB. I'm able to access the USB from a 
similar desktop running LM installed on its SSD.

Phase II

Pi 3B, 1G ram, running '25 May Raspbian ie Deb 12 LXDE/OB from SD. 
Install Webmin/samba and similarly used that to share a USB connected hd 
sata spinner.  I am NOT able to access that external hd from my LAN w/ 
such as the above installed LM desktop; that is, I can /see/ it, but the 
authentication window step fails and just repeats.

I've got exactly the same problem, all my devices connect to my Pi NAS 
(aka a Pi 5 with an USB to SATA SSD) via NFS with no problem, but my 
wife who still uses Microslop gets the same error when trying to connect 
to the Samba shares from Windows 11. It's a fairly recent M$ breakage as 
it was all working a couple of months ago before we moved house.

No doubt fixing it involves some buggering around with the Windows 
registry, but I haven't got around to spending several hours looking at 
search results with obviously wrong solutions (by AI), or even wrongerer 
solutions (by MSVPs).

The truth is out there - somewhere.

I'm not a commandline smarty, but I was wondering if there were a way to 
try to access the share from the commandline instead of the GUI file 
manager, then when the authentication failed, there might be some kind 
of failure message that could be useful.

Or, maybe I should look at the situation of the desired share w/o using 
the Webmin, so I could tell if there were something 'wrong w/ it' - the 
share condition.

There are quite a few useful tools at the client end to test
connections, authentication etc: nmblookup, smbtree, and in particular
smbclient.

E.g. to get a listing of shares visible to a given username/password:

    smbclient -U «username»%«password» -L «server-addr»

Specify domain as well:

    smbclient -U «username»%«password» -W «domain» ...

Access a particular share:

    smbclient //«server/«share-name» -U «username» «password»

(Hmm, there might be a typo in my notes ... might need a “%” instead
of a blank between «username» and «password».)

Here’s a tip for troublesome Windows clients: they could be trying to
use an obsolete connection protocol version or authentication protocol
version that your Samba server is not configured to allow.

Well that's what I thought after watching the documentary on Disney, but 
the balloons wouldn't lift the house with everything inside.

Here in NZ, we put them on the backs of big trucks, and transport them
by road.

Yes, I have once or twice had to pull to the side of the road to make
way for a house coming the other way ...

I'd love to move my house to New Zealand, but how would I choose where? 
I saw so many wonderful locations on north and south islands when I was 
down there last year to see the folks. I hope to be back again next year 
to see some more.

I fear my house is a bit on the large size for that, and your roads 
aren't any wider than ours. I could get a little place in Herne bay and 
spend half the year there, but the wife and I can't decide which half, I 
like summers and she likes winters.

Anyway I fear we are getting a bit off topic, so I should mention I took 
a Raspberry Pi 4B with me last time to show people RISC OS. I'd 
forgotten to pack the micro HDMI cable, but managed to pick one up at 
first stop in Christchurch, and even had it working with the TV in the 
camper-van on South Island.

Possibly not. A Windows update may have screwed with the security 
settings.

My Windows 11 PC connects quite happily to my Pi5 and my Pi4 based RISC OS 
device.

Fairly (!) simple to check on Windows 11:

1. Go to Control Panel
2. Open Network and Sharing Centre
3. In the left column, click on Changed Advanced Sharing settings
4. Make sure firstly that sharing is enabled
5. Expand the All Networks section

I have the Encryption set to 40- or 56-bit, but Windows may have defaulted 
to 128-bit. I don't know enough about older Pis as per the OP, but it's 
probably worth exploring the above settings on the Windows side.

I'm getting deja vu.  M$ brought out a service pack for Windows 2000 
which included a patch that made its SMB server issue an invalid command
to clients trying to connect, and then check the error message that came
back.  If the error message returned by the client (in this case Samba)
wasn't worded exactly the way an M$ client would do it, then the server
would refuse to connect.

(I might have server and client backwards here, it was a long time ago.)

It took the Samba authors about two days to fix that one, and
I continued happily connecting to Windows shares from my Amiga.

I just don't get this stuff. I have a Win 11 pro workstation, 4 Pis, and 
two mini PCS, one Intel, one AMD - both with Ubuntu LTS

I have samba on all and I don't have any problems at all. OK if I want 
linux to linux comms, I would just use NFS

I haven't been working on this (diligently or otherwise), but now I'm
looking over the webmin docs (/very/ extensive) and I believe that is
going to give me some guidance to work on this.

BTW, for the earlier Win comments, the webmin docs have a fair amount to
say about that:

https://webmin.com/docs/modules/samba-windows-file-sharing/

Currently I'm only working on linux rpi sharing.
