In our example we have created a UNIX/Linux group called ntadmin. Our script will create the additional groups Orks, Elves, and Gnomes. It is a good idea to save this shell script for later use just in case you ever need to rebuild your mapping database. For the sake of convenience we elect to save this script as a file called initGroups.sh. This script is given in intGroups.sh.

#!/bin/bash

net groupmap modify ntgroup="Domain Admins" unixgroup=ntadmin
net groupmap modify ntgroup="Domain Users" unixgroup=users
net groupmap modify ntgroup="Domain Guests" unixgroup=nobody

groupadd Orks
groupadd Elves
groupadd Gnomes

net groupmap add ntgroup="Orks"   unixgroup=Orks   type=d
net groupmap add ntgroup="Elves"  unixgroup=Elves  type=d
net groupmap add ntgroup="Gnomes" unixgroup=Gnomes type=d

Of course it is expected that the administrator will modify this to suit local needs. For information regarding the use of the net groupmap tool please refer to the man page.
