Requested logs. The failed first authentication is on Apr 21 11:05:28, immediatly after the second attempt succeeds.
Before I logged in with the domain account I checked that networking of the machine worked: wbinfo -P and wbinfo -p both showed online, wbinfo -u displayed every user. The DC is a Ubuntu 16.04 samba active directory. In a similar setup where I have the same problem I use a "18.04" ubuntu samba dc, but lets stay with this machine since I can reproduce the problem very reliably and the machine reboots quickly. /etc/nsswitch has the following setup: passwd: compat winbind systemd group: compat winbind systemd shadow: compat gshadow: files hosts: files resolve dns mdns_minimal networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis ** Attachment added: "logs.tar.xz" https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1764853/+attachment/5124840/+files/logs.tar.xz -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
