Good news! I installed the update and rebooted and it did not work, smbclient commands returned NT_STATUS_NO_LOGON_SERVERS. But after also adding "client ipc signing = auto" to smbd.conf as per Tony Haley's recommendation in comment #20, and after another reboot, it is working as expected with just the 4.1.6 DCs in service (it worked with the 4.3.8 servers even before this update).
I'm relieved to know that if I have to take down my new PDC for maintenance, this old 12.04.5 server will not suddenly stop working when it has to authenticate against the other DCs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1572824 Title: Samba Domain Member cannot check passwords against Samba AD DC after "Badlock" update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1572824/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
