Instead of running `id -ng` several times you can hard code the values

XXX echo "domain users and groups are listed in the "/etc/passwd and /etc/group files."

Let's make it fail safe, avoid invoking cat and set the mode
	sed -e 's/mkgroup_l_d/mkgroup-l-d/' /etc/group > /etc/group.new \
        && mv /etc/group /etc/group.mkgroup_l_d
        && (mv /etc/group.new /etc/group ||  mv /etc/group.mkgroup_l_d /etc/group ; )
	chmod a+r /etc/group 
        rm -f /etc/group.mkgroup_l_d
