Check Text ( C-16535r294462_chk )
From the command prompt, run the following command to check the default "logindelay" value:
# lssec -f /etc/security/login.cfg -s default -a logindelay

The above command should yield the following output:
default logindelay=4

If the above command displays the "logindelay" value less than "4", this is a finding.
