Please attach these logs from when the login failure happens: - /var/log/auth.log - /var/log/syslog - /var/log/samba/log*
I configured a VM with your smb.conf, joined a windows 2016 AD server via net ads join -k and AD users can login just fine immediately after a reboot. I also used your netplan file, and I have no /etc/network/interfaces or interfaces.d/* content. I didn't upgrade from xenial, though, this was a fresh bionic install. Since this is a VM I provisioned with uvt-kvm, there are a few differences from a normal desktop install: - I did "apt install ubuntu-desktop" after provisioning the vm - I removed the cloud-init package after provisioning - my dns and dhcp server is not the AD server, although I used its DNS server temporarily when doing "net ads join" so that the server could be found I could try a fresh bionic *desktop* install, I know it could configure networking a bit differently, or even install a xenial desktop and then upgrade, but let's start with the logs I requested above. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1764853 Title: winbind returns PAM_AUTHINFO_UNAVAIL on first login after reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1764853/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
