Hi, by making my own distribution everything seems to be good for the moment except one thing. I've create my own installation installation by creating server.py in anaconda-10.1.0.2/installclasses/ I've put the dispatch.skipStep("authentication") line in the server.py file. Then during installation no problem and after reboot I could see in the anaconda-ks.cfg file only the authconfig --enablemd5 validated. There no /etc/shadow on the system. how can I make change in anaconda not to choose authentication during installation and validate shadow password ? Thanks for Help Vincent
