This works for me under Fedora 14:
# groups USERNAME
USERNAME : USERNAME GROUPNAME
# usermod -G $(id -Gn USERNAME | sed "s/GROUPNAME//g" | sed "s/ /,/g" | sed
"s/,,/,/g" | sed "s/,$//g") USERNAME
# groups USERNAME
USERNAME : USERNAME

Do some light scripting with an appropriate utility, e.g. userinfo(8).
