Code:
$ u=user1
$ sed -n '/^group/h; /'"$u"'/{g;s/[[:blank:]].*$//;p;}' file
group1
group2

I would recommend against using this type of solution unless you can guarantee that the user name will not contain any sed regular expression special characters ("/", ".", "*", "\" .. come immediately to mind).

You have been warned Smilie
