Interestingly, while trying to fix this, i found that it seems to be related to ip addressing/hostnames.
As far as i can see, the name returned from 'hostname' must have an entry in /etc/hosts mapping it to 127.0.0.1 Setting this up returned my kcontrol administrator access. In my /etc/hosts file, the hostname of my workstation was mapped to 127.0.1.1. I'm pretty sure this was set up automatically by the ubuntu gutsy installer. I hope this helps with the once-and-for-all elimination of this bug -- Administrator button fails to work in kde-settings and kcontrol https://bugs.launchpad.net/bugs/175909 You received this bug notification because you are a member of Kubuntu Team, which is subscribed to kde-systemsettings in ubuntu. -- kubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
