[Bug 2060676] Re: login: remove pam_lastlog.so from config

[Seth Arnold]

Andrei, try to log in via multiple methods. Every service (ssh, login,
gdm, xdm, etc) has its own PAM configuration and some of them may
reference this module and some may not.

Once you've logged in, edit the files in /etc/pam.d/ that reference this
module. Remove or comment them out. Save, then test. Don't quit any root
shells in the process of testing, because changing PAM configuration can
lock you out of your system -- as you've discovered.

Thanks

Title:
  login: remove pam_lastlog.so from config

Status in shadow package in Ubuntu:
  Confirmed
Status in shadow package in Debian:
  Fix Released

Bug description:
  Imported from Debian bug http://bugs.debian.org/1068229:

  Package: libpam-modules
  Version: 1.5.3-6
  Severity: normal

  I noticed the following line in my logs:

  login[2449]: PAM unable to dlopen(pam_lastlog.so):
  /usr/lib/security/pam_lastlog.so: cannot open shared object file: No
  such file or directory

  I looked in the deb files from snapshot.debian.org, and noticed the last version
  that had it was 1.5.2-9.1 - starting from 1.5.3-1 it disappeared.

  Maybe it's fallout from the time_t transition and you're already aware of it, in
  which case feel free to close.

  Thanks,
