Auto login without specifying MAC address

From K12LTSP Wiki

If you want all your clients to auto-login, create the /usr/local/bin/autologin script so that all workstations get assigned an autologin ID, like so:

   #!/bin/bash
   CLIENT=$(echo $DISPLAY | cut -d. -f1)
   case "$CLIENT" in
        "ws001")    disp=auto1;;
        "ws002")    disp=auto2;;
      # repeat this for all ws numbers listed in /etc/hosts
        "ws253")    disp=auto253;;
   esac
   echo $disp

Then, create logins IDs auto1 through auto253. That way, no matter what address a client machine gets, autologin will work, and you don't have to specify MAC addresses in dhcpd.conf. You do not have to create passwords for the login IDs, but if you don't, be sure to turn off the password requirement in the screensaver or users won't be able to get back in once the screensaver kicks in.
