Comment 5 for bug 75098

NSCD will not make it into main and get installed out of the box for a multitude of reasons, one being the issue you noticed and another big issue is its interaction and breakage/disruption of samba, which more of our users use than NSCD. KDE has made it clear they won't be including the NSCD like caching in their KIO slaves since NSCD already provides this. And if you read through that entire thread, they also talk about glibc bugs as well. So this is why I also closed this bug, an NSCD wishlist item won't make it.

Only thing I can think of would be a GUI interface to turn on/off ipv6. Now if you want to, reopen a new report for such a feature against kubuntu-meta or kubuntu-default-settings, and I will confirm it, and see if what we can do. How does that sound?
