The command should be
# usermod -G <group1,group2...> <username>
When doing it this way you need to specify ALL the groups the user
belongs to as this does not append to the current list. So to get a list
of groups a user may be associated with type
# groups <username>
Then take the output to be used with usermod command. Or you can just
edit the /etc/groups file by hand
