Bug Description

When using user management tools such as usermod we see spurious messages due to unscd, for example:

  # usermod -a -G testgroup username
  sent invalidate(passwd) request, exiting
  sent invalidate(group) request, exiting
  sent invalidate(passwd) request, exiting
  sent invalidate(group) request, exiting

The command completes successfully, but the spurious message looks like an error and causes concern among our users. This issue was apparently fixed in Debian here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=622230. Can Ubuntu please take this fix?
