You probably could have prevented the mess in the first place by
supplying the user's groups on the command line, see 'man useradd' for
instructions.

Also, using adduser is better (man useradd: "useradd is a low level
utility for adding users. On Debian, administrators should usually use
adduser(8) instead").

Of course, you also could have used the GUI utility to add users and put
them into groups :)
