[Bug 1872443] Re: /etc/securetty missing: dovecot not working

[Dr. Uwe Meyer-Gruhl]

I cannot tell if this is a problem in whatever version of Debian, since
I do not use it.

Even with Ubuntu being derived from Debian at some point between 18.04
where /etc/securetty was delivered with package login and 20.04 where
the whole package is unavailable.

I think that is an interdependence between multiple packages, but I am
not quite in the position to point at where (or even if) the problem
could be fixed in Debian.

Title:
  /etc/securetty missing: dovecot not working

Status in shadow package in Ubuntu:
  New

Bug description:
  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.
