http://ubuntuforums.org – Hi All, I have Ubuntu server 12.04.1 64bit in a virtualbox VM using bridges networking under Mint14 following this guide to setup samba4 as an exercise of interest. (http://www.matrix44.net/cms/notes/gn...h-ubuntu-12-04) All went well until I got to the Kerberos setup section and it failed to pass the testing mentioned in the guide. (Hardware)
