Fix Recommendation

Add the following line to the "/etc/pam.d/system-auth" file (or modify the line to have the required value):

password required pam_pwquality.so retry=3

Check Contents

Verify TOSS 5 is configured to limit the "pwquality" retry option to "3".

Verify the use of the "pwquality" retry option in the "system-auth file" using the following command:

$ cat /etc/pam.d/system-auth | grep pam_pwquality

password required pam_pwquality.so retry=3
