# Rule ID: RHEL-06-000054_rule
# Severity: low
# Rule Version (STIG-ID): RHEL-06-000054
# Rule Title: Users must be warned 7 days in advance of password 
# expiration.
#
# Vulnerability Discussion: Setting the password warning age enables 
# users to make the change at a practical time.
#
# Responsibility: 
# IAControls: 
#
# Check Content:
#
# To check the password warning age, run the command: 

# $ grep PASS_WARN_AGE /etc/login.defs

# The DoD requirement is 7. 
# If it is not set to the required value, this is a finding.
#
# Fix Text: 
#
# To specify how many days prior to password expiration that a warning 
# will be issued to users, edit the file "/etc/login.defs" and add or 
# correct the following line, replacing [DAYS] appropriately: 

# PASS_WARN_AGE [DAYS]

# The DoD requirement is 7.
