Description firewalker 2021-07-11 06:48:15 UTC

I have a windows 10 pc with some passwordless shared folders. I can access those folders anonymously (user:anonymous, password:anonymous).

Using smbclient I can login without problems

smbclient //192.168.1.69/shared/ -U anonymous 

or
 
smbclient //192.168.1.69/shared/ -N

The problem is with Dolphin. It asks for a password and it can't accept anonymous. Eg. smb://anonymous:anonymous@192.168.1.69/shared/ will fail to login and Dolphin asks for password.

Comment 1 Harald Sitter 2021-07-13 10:32:52 UTC

Passwords get stripped from URIs somewhere along the way, you have to actually supply anonymous:anonymous to the password dialog.

Comment 2 firewalker 2021-07-13 11:10:55 UTC

If you mean like the image below, it doesn;t work. With any iteration on the fields of the authentication dialog.

Comment 3 Harald Sitter 2021-07-13 11:32:22 UTC

No. You need to provide the username anonymous and you need to provide the password anonymous. That is what anonymous:anonymous means in a URI.

Comment 4 firewalker 2021-07-13 11:44:53 UTC

This is the first thing I did. If I provide anonymous in the user field and anonymous in the password filed. It doesn;t do anything, it shows again the same authentication dialog.

Comment 5 Harald Sitter 2021-07-13 11:57:51 UTC

Well, the log you provided is of you cancelling the dialog :)

Comment 7 firewalker 2021-07-13 12:25:49 UTC

The debug info was generated by instructions of your link. See the attached video with the issue. I am not canceling the authentication dialog....

Comment 8 Harald Sitter 2021-07-13 12:39:16 UTC

Perhaps it's the same as this problem? https://www.spinics.net/lists/samba/msg167472.html

Comment 9 firewalker 2021-07-13 12:49:24 UTC

I don;t think it is. every other program (smbclient, smb4k) logins anonymously just fine. Also dolphin works just fine with password protected shares. The only issue is with paswordless shares.

Comment 10 Harald Sitter 2021-07-13 12:53:19 UTC

The thing is, there's nothing special going on. From our side an anonymous login is like any other. So whatever is wrong might be within libsmbclient, but supposedly that is also what sits underneath smbclient.

It's likely that `Bad SMB2 signature for message` is the actual problem here, but that comes out of libsmbclient and I don't know anything about it's internals. 

Have you tried a name different than anonymous?

Comment 11 firewalker 2021-07-13 13:05:43 UTC

Yes, it doesnt work.

Comment 12 Harald Sitter 2021-07-13 14:29:05 UTC

Can you provide detailed instructions on how you've set up windows (and samba if you've configured anything there)?

Comment 13 firewalker 2021-07-14 06:07:35 UTC

You "Turn off password protected sharing" from control panel and then share a folder (right click, properties, sharing, share) adding everyone to the list.
