Fix Recommendation

Configure OL 9 to enforce password complexity by requiring at least one special character be used by setting the "ocredit" option.

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

ocredit = -1

Check Contents

Verify that OL 9 enforces password complexity by requiring at least one special character with the following command:

$ sudo grep ocredit /etc/security/pwquality.conf /etc/security/pwquality.conf.d/*.conf
ocredit = -1

If the value of "ocredit" is a positive number or is commented out, this is a finding.
