Windows 11 can not connect to guest ksmbd share.

[ivanmara555]

Hello. I have test arch linux with ksmbd v3.5.2 and simple guest share config /etc/ksmbd/ksmbd.conf:

[global]
    map to guest = bad user

[data]
    path = /mnt/sdb/data
    force user = quanta
    read only = no
    guest ok = yes

In windows 10 i enable insecure guest logons policy:

gpedit - Computer Configuration - Administrative templates - Network - Lanman Workstation: Enable insecure guest logons: On

Using explorer i simply connect to open ksmbd share: \\192.168.122.1\data end everything ok (file listing, read/write)

Using xfce thunar i connect normal with: smb://192.168.122.1/data

Using mount.cifs -o guest //192.168.122.1/data /tmp/test everything ok too.

But when i use Windows 11 with enabled insecure guest logons policy connection brocken. Firewall disabed.

What can i do to connect windows 11 to open ksmbd share?

ps:
In Openwrt i have same troubles with windows 11 and open ksmbd share.
Windows 11 connect normal to user/password protected ksmbd share.

what is the error ?
The blogpost below suggests that the following powershell commands should enable guest logon:

Set-SmbClientConfiguration -RequireSecuritySignature $false
Set-SmbClientConfiguration -EnableInsecureGuestLogons $true -Force

Error on screenshot

But after running your commands:

Set-SmbClientConfiguration -RequireSecuritySignature $false -Force
Set-SmbClientConfiguration -EnableInsecureGuestLogons $true -Force

Windows 11 now connect to ksmbd guest share on linux and openwrt server:

Thanx for your help!
