Fix Recommendation

Configure the operating system to enforce password complexity by requiring that at least one lower-case character be used by setting the "lcredit" option.

Add the following line to /etc/security/pwquality.conf (or modify the line to have the required value):

lcredit = -1

Remove any configurations that conflict with the above value.

Check Contents

Verify the value for "lcredit" with the following command:

$ sudo grep -r lcredit /etc/security/pwquality.conf*

/etc/security/pwquality.conf:lcredit = -1

If the value of "lcredit" is a positive number or is commented out, this is a finding.
If conflicting results are returned, this is a finding.
