PURPOSE of /CoreOS/openssh/Sanity/pam_ssh_agent_auth
Description: This is basic sanity test for pam_ssh_agent_auth
Author: Jakub Jelen <jjelen@redhat.com>
Created as a response to rhbz#1251777 and previous one rhbz#1225106.
The code of pam module is outdated and compiled with current openssh
version which went through quite enough refactoring.
