This usually is a filesystem or file corruption issue....A few things to check:
- The filesystem(s) that hold /etc, /var and /tmp have disk space available
- The /etc/passwd, /etc/group, /etc/security/user, /etc/security/login, /etc/security/passwd and /usr/lib/securty/methods.cfg have correct permissions
- On later AIX try running "userck" to check the validity of the above files
- If you have an earlier version of AIX, check for blank lines in /etc/passwd and /etc/group, and look for double blank lines or corruption in /etc/security/users, /etc/security/login and /etc/security/passwd
- Is your system configured to authenticate against an external security database, for eg NIS or LDAP ?
I hope this helps...

CHECKSECURITY(8) System Manager's Manual CHECKSECURITY(8)
NAME
checksecurity - Run a collection of simple system checks
SYNOPSIS
checksecurity
DESCRIPTION
The checksecurity command runs a small collection of simple system checks which are designed to catch a few common security issues. check-
security is run by cron in a daily basis.
CONFIGURATION
The checksecurity.conf file defines several configuration variables: MAILTO, CHECK_DISKFREE, CHECK_PASSWD and CHECK_SETUID LOGDIR. Each is
described below.
The checksecurity program works with a collection of plugins which are located in /usr/share/checksecurity and are configured individually
by their own configuration file.
CHECK_PASSWD If this is set to TRUE then the check-passwd script will be invoked. This script is designed to report upon system accounts
which have no passwords. CHECK_DISKFREE If this is set to TRUE then the check-diskfree script will be invoked and will allow an alert to
be sent if there is any mounted partition is running short on disk space. CHECK_SETUID If this is set to TRUE then the check-setuid script
will be invoked, this will compare the setuid binaries upon the system to those that existed previously and show the differences.
