Public bug reported: With Ubuntu 20.04 Focal Fossa, /etc/securetty is missing from the "login" package (4.8.1-1ubuntu4).
This leads to errors such as in /var/log/mail.log when a dovecot auth is tried: Apr 13 13:08:17 venus dovecot[10588]: imap-login: Login: user=<tttt>, method=PLAIN, rip=192.168.123.1, lip=192.168.123.188, mpid=12200, TLS, TLSv1.2 with cipher ECDHE-E CDSA-AES256-GCM-SHA384 (256/256 bits) Apr 13 13:08:18 venus auth[12195]: pam_unix(dovecot:auth): Couldn't open /etc/secure tty: No such file or directory Apr 13 13:08:18 venus auth[12195]: pam_unix(dovecot:auth): Couldn't open /etc/secure tty: No such file or directory Apr 13 13:08:18 venus dovecot[10588]: imap-login: Login: user=<tttt>, method=PLAIN, rip=192.168.123.1, lip=192.168.123.188, mpid=12202, TLS, TLSv1.2 with cipher ECDHE-E CDSA-AES256-GCM-SHA384 (256/256 bits) It seems that pam_unix still needs /etc/securetty, but login no longer provides it. There was a similar bug in debian that seems to be related: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=931899 To my understanding, this is a problem between pam and login packages in 20.04. ** Affects: shadow (Ubuntu) Importance: Undecided Status: New ** Tags: dovecot login pam securetty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872443 Title: /etc/securetty missing: dovecot not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shadow/+bug/1872443/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
