  34 NUUG presentation</a> about Kerberos was inspiring, and reminded me
  35 about the need to start using Kerberos in Skolelinux.  Setting up a
  36 Kerberos server seem to be straight forward, and if we get this in
  37 place a long time before the Squeeze version of Debian freezes, we
  38 have a chance to migrate Skolelinux away from NFSv3 for the home
  39 directories, and over to an architecture where the infrastructure do
  40 not have to trust IP addresses and machines, and instead can trust
  41 users and cryptographic keys instead.</p>
  42
  43 <p>A challenge will be integration and administration.  Is there a
  44 Kerberos implementation for Debian where one can control the
  45 administration access in Kerberos using LDAP groups?  With it, the
  46 school administration will have to maintain access control using flat
  47 files on the main server, which give a huge potential for errors.</p>
  48
  49 <p>A related question I would like to know is how well Kerberos and
  50 pam-ccreds (offline password check) work together.  Anyone know?</p>
  51
  52 <p>Next step will be to use Kerberos for access control in Lwat and
  53 Nagios.  I have no idea how much work that will be to implement.  We
  54 would also need to document how to integrate with Windows AD, as such
  55 shared network will require two Kerberos realms that need to cooperate
  56 to work properly.</p>
  57
  58 <p>I believe a good start would be to start using Kerberos on the
  59 skolelinux.no machines, and this way get ourselves experience with
  60 configuration and integration.  A natural starting point would be
  61 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
  62 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
  63 time.</p>
  64
  65 <p>If you would like to contribute to get this working in Skolelinux,
  66 I recommend you to see the video recording from yesterdays NUUG
  67 presentation, and start using Kerberos at home.  The video show show
  68 up in a few days.</p>

  91 <p>The last few weeks i have had the pleasure of reading a
  92 thought-provoking collection of essays by Cory Doctorow, on topics
  93 touching copyright, virtual worlds, the future of man when the
  94 conscience mind can be duplicated into a computer and many more. The
  95 book titled "Content: Selected Essays on Technology, Creativity,
  96 Copyright, and the Future of the Future" is available with few
  97 restrictions on the web, for example from
  98 <a href="http://craphound.com/content/">his own site</a>. I read the
  99 epub-version from
 100 <a href="http://www.feedbooks.com/book/2883">feedbooks</a> using
 101 <a href="http://www.fbreader.org/">fbreader</a> and my N810. I
 102 strongly recommend this book.</p>
