Verified for openssh as well; it now correctly shows entries in aureport
-l too.

Attached is a transcript from the two sessions testing shadow and
openssh for audit support.

Bug description:
  [Impact]
  Auditing support is a commonly used feature in large enterprises, and allows better tracking of actions happening on secured systems, especially when it comes to accounting for login events.

  Such systems fail to correctly list login events in aureport due to
  some software not integrating libaudit.

  [Test Case]
  1) Install auditd
  2) Login to the system multiple times (or allow for others to connect to the system)
  3) Run aureport -l

  System should list login information.

  [Regression Potential]
  There is minimal risk for issues since libaudit support only allows for generating extra logging saved on the local system. A possible side-effect of this may be that systems on which auditing is enabled and where there are many users of the affected software (see bug tasks), such as many logins over SSH, there may be an increased demand on disk space necessary for the auditing data.

  -- Problem Description --
  We installed ubuntu 14.04.3 on lakelp1 and installed package auditd. We tried to
  ssh to lakelp1 several times and found that "aureport -l" couldn't print out the login
  info.

  root@lakelp1:~# /etc/init.d/auditd status
   * auditd is running.

  root@lakelp1:~# auditctl -e 1

  This looks like a bug in aureport or libaudit. In addition to giving
  admins falsely empty record selections, this would prevent successful
  completion of a Common Criteria certification.
