Use this script:
#! /bin/bash
#
for i in $(cat /etc/passwd | cut -d: -f1); do
echo -n $i ": "
grep $i /etc/group | cut -d: -f1 | tr "\n" " "
echo
done
It will list all users in the system (included system) and print the list of groups near them. With a trivial modification you can print the numeric id too.
