Done.  The proposed patch is in the attached file.

Had a chance to read this closer. What's the reason for inclusion? This would step beyond the baseline of even USGCB.

RHEL5 CCE-3987-5:
CCE-3987-5 Login access to non-root system accounts should be enabled or disabled as appropriate  disabled  via /etc/passwd List all users, their UIDs, and their shells by running:
# awk -F: '{print $1 ":" $3 ":" $7}' /etc/passwd
For each identified system account SYSACCT , lock the account:
# usermod -L SYSACCT
and disable its shell:
# usermod -s /sbin/nologin SYSACCT


Maps to RHEL6 CCE-26966-2:
Some accounts are not associated with a human user of the system, and exist to perform some administrative function. Should an attacker be able to log into these accounts, they should not be granted access to a shell. 

The login shell for each local account is stored in the last field of each line in /etc/passwd. System accounts are those user accounts with a user ID less than 500. The user ID is stored in the third field. If any system account SYSACCT (other than root) has a login shell, disable it with the command:
# usermod -s /sbin/nologin SYSACCT
