  24       <div class="date">28th April 2010</div>
  25       <div class="body"><p>For some years now, I have wondered how we should handle laptops in
  26 Debian Edu.  The Debian Edu infrastructure is mostly designed to
  27 handle stationary computers, and less suited for computers that come
  28 and go.</p>
  29
  30 <p>Now I finally believe I have an sensible idea on how to adjust
  31 Debian Edu for laptops, by introducing a new profile for them, for
  32 example called Roaming Workstations.  Here are my thought on this.
  33 The setup would consist of the following:</p>
  34
  35 <ul>
  36
  37  <li>During installation, the user name of the owner / primary user of
  38    the laptop is requested and a local home directory is set up for
  39    the user, with uid and gid information fetched from the LDAP
  40    server.  This allow the user to work also when offline.  The
  41    central home directory can be available in a subdirectory on
  42    request, for example mounted via CIFS.  It could be mounted
  43    automatically when a user log in while on the Debian Edu network,
  44    and unmounted when the machine is taken away (network down,
  45    hibernate, etc), it can be set up to do automatic mounting on
  46    request (using autofs), or perhaps some GUI button on the desktop
  47    can be used to access it when needed.  Perhaps it is enough to use
  48    the fish protocol in KDE?</li>
  49
  50  <li>Password checking is set up to use LDAP or Kerberos
  51    authentication when the machine is on the Debian Edu network, and
  52    to cache the password for offline checking when the machine unable
  53    to reach the LDAP or Kerberos server.  This can be done using
  54    <a href="http://www.padl.com/OSS/pam_ccreds.html">libpam-ccreds</a>
  55    or the Fedora developed
  56    <a href="https://fedoraproject.org/wiki/Features/SSSD">System
  57    Security Services Daemon</a> packages.</li>
  58
  59  <li>File synchronisation with the central home directory is set up
  60    using a shared directory in both the local and the central home
  61    directory, using unison.</li>
  62
  63  <li>Printing should be set up to print to all printers broadcasting
  64    their existence on the local network, and should then work out of
  65    the box with CUPS.  For sites needing accurate printer quotas, some
  66    system with Kerberos authentication or printing via ssh could be
  67    implemented.</li>
  68
  69  <li>For users that should have local root access to their laptop,
  70    sudo should be used to allow this to the local user.</li>
  71
  72  <li>It would be nice if user and group information from LDAP is
  73    cached on the client, but given that there are entries for the
  74    local user and primary group in /etc/, it should not be needed.</li>
  75
  76 </ul>
  77
  78 <p>I believe all the pieces to implement this are in Debian/testing at
  79 the moment.  If we work quickly, we should be able to get this ready
  80 in time for the Squeeze release to freeze.  Some of the pieces need
  81 tweaking, like libpam-ccreds should get support for pam-auth-update
  82 (<a href="http://bugs.debian.org/566718">#566718</a>) and nslcd (or
  83 perhaps debian-edu-config) should get some integration code to stop
  84 its daemon when the LDAP server is unavailable to avoid long timeouts
  85 when disconnected from the net.  If we get Kerberos enabled, we need
  86 to make sure we avoid long timeouts there too.</p>
  87
  88 <p>If you want to help out with implementing this for Debian Edu,
  89 please contact us on debian-edu@lists.debian.org.</p>
