Migrate System Accounts to another Server

Cloning AIX users and groups between servers

# one-liner to generate the commands to clone groups
lsgroup -c -a id ALL | grep -v ^# | awk -F: '{print "mkgroup id=" $2, $1}'

# one-liner to generate the commnads to clone users
lsuser -c -a id pgrp groups home shell gecos ALL | grep -v ^# | awk -F: '{print "useradd -m -u", $2, "-g", $3, "-G", $4, "-c \"" $7 "\" -d ", $5, $1}'

Copying AIX password hashes between servers

# grep -p root /etc/security/passwd
root:
password = 2zfymAdUyNdA.
lastupdate = 1360555127

echo 'root:2zfymAdUyNdA.' | chpasswd -ec

gen_reset_password.sh:

#!/usr/bin/ksh

for user in `lsuser -a ALL`; do
        [ -n "$1" -a "$user" != "$1" ] && continue
        if grep -p ^${user}: /etc/security/passwd | grep -q "password = "; then
                hash=`grep -p ^${user}: /etc/security/passwd | grep "password = " | awk -F " = " '{print $2}'`
                echo "echo '${user}:${hash}' | chpasswd -ec"
        fi
done

# ./gen_reset_password.sh
