Title

The AIX /etc/passwd, /etc/security/passwd, and/or /etc/group files must not contain a plus (+) without defining entries for NIS+ netgroups or LDAP netgroups. (Cat II impact)

Discussion

A plus (+) in system accounts files causes the system to lookup the specified entry using NIS. If the system is not using NIS, no such entries should exist.

Check Content

Check system configuration files for plus (+) entries using the following commands: # cat /etc/passwd | grep -v "^#" | grep "\+" # cat /etc/security/passwd | grep -v "^#" | grep "\+" # cat /etc/group | grep -v "^#" | grep "\+" If the "/etc/passwd", "/etc/security/passwd", and/or "/etc/group" files contain a plus (+) and do not define entries for NIS+ netgroups or LDAP netgroups, this is a finding.

Fix Text

Edit "/etc/passwd", "/etc/security/passwd", and/or "/etc/group" files and remove entries containing a plus (+).
