All AIX Group Identifiers (GIDs) referenced in the /etc/passwd file must be defined in the /etc/group file.

If a user is assigned the GID of a group not existing on the system, and a group with that GID is subsequently created, the user may have unintended rights to the group.

Verify that there are no GIDs referenced in "/etc/passwd" that are not defined in "/etc/group":

# cut -d: -f4 /etc/passwd 0 1 2 3 4 203 204

# cut -d: -f3 /etc/group 0 1 2 3 4 203 204

If there are GID's listed in the "/etc/passwd" file that are not listed in the "/etc/group" file, this is a finding.

Add a group to the system for each GID referenced without a corresponding group by running "mkgroup" command.
