    cp -p /etc/security/pwquality.conf /etc/security/pwquality.conf-`date +%F_%H:%M:%S`.back

  3. Configure the settings according to the requirements of your organization.

    sed -i -E 's/dcredit = [-]?[0-9]+$/dcredit = <your_value>/g' /etc/security/pwquality.conf
sed -i -E 's/ucredit = [-]?[0-9]+$/ucredit = <your_value>/g' /etc/security/pwquality.conf
sed -i -E 's/lcredit = [-]?[0-9]+$/lcredit = <your_value>/g' /etc/security/pwquality.conf
sed -i -E 's/ocredit = [-]?[0-9]+$/ocredit = <your_value>/g' /etc/security/pwquality.conf
sed -i 's/^\s*#*\s*minlen\s*=\s*[0-9]\+/minlen = <your_value>/g' /etc/security/pwquality.conf
sed -i 's/^\s*#*\s*minclass\s*=\s*[0-9]\+/minclass = <your_value>/g' /etc/security/pwquality.conf
sed -i -E 's/difok = [-]?[0-9]+$/difok = <your_value>/g' /etc/security/pwquality.conf
sed -i 's/^\s*#*\s*maxrepeat\s*=\s*[0-9]\+/maxrepeat = <your_value>/g' /etc/security/pwquality.conf
sed -i 's/^\s*#*\s*retry\s*=\s*[0-9]\+/retry = <your_value>/g' /etc/security/pwquality.conf

  4. Back up the /etc/security/pwhistory.conf file for the appliance.

    cp -p /etc/security/pwhistory.conf /etc/security/pwhistory.conf-`date +%F_%H:%M:%S`.back

  5. Enable it for the root user, and update the remember settings, using values that meet the requirements of your organization.

    sed -i 's/^# enforce_for_root/enforce_for_root/' /etc/security/pwhistory.conf
sed -i -E 's/remember = [-]?[0-9]+$/remember = <your_value>/g' /etc/security/pwhistory.conf
  6. Verify the values.
    cat /etc/security/pwquality.conf
cat /etc/security/pwhistory.conf
  7. Repeat the procedure for each of the remaining VMware Aria Operations for Logs appliances.
