[Bug 1478087] Re: Add libaudit support

[Mathieu Trudel-Lapierre]

** Description changed:

+ [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.

  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.
