Comment 67 for bug 2027716

FYI in case useful, I've also tested the jammy-proposed samba package on a samba DC with Windows PCs on the domain. Prior to this fix, we were not able to log in with domain accounts via remote desktop to Windows PCs (Windows RDP or remmina from Linux) and the powershell 'Test-ComputerSecureChannel -Verbose' gave false. Having installed the jammy-proposed package, this now works (did have to reboot for my test Windows 10 VM to pick up the change for 'Test-ComputerSecureChannel -Verbose' to return true).

To install, after adding the jammy-proposed apt source and selective upgrading as per https://wiki.ubuntu.com/Testing/EnableProposed, I ran

  sudo apt install --dry-run samba/jammy-proposed ...

repeatedly to determine the correct dependencies, and ended up with the following:

  sudo apt install samba/jammy-proposed samba-common-bin/jammy-proposed libwbclient0/jammy-proposed \
    samba-libs/jammy-proposed python3-samba/jammy-proposed libnss-winbind/jammy-proposed \
    libsmbclient/jammy-proposed samba-dsdb-modules/jammy-proposed samba-vfs-modules/jammy-proposed \
    smbclient/jammy-proposed winbind/jammy-proposed

and then restarted the service:

  sudo systemctl restart samba-ad-dc.service

apt-cache policy samba
