+		<description>&lt;p&gt;The state of standardized LDAP schemas on Linux is far from
+optimal.  There is RFC 2307 documenting one way to store NIS maps in
+LDAP, and a modified version of this normally called RFC 2307bis, with
+some modifications to be compatible with Active Directory.  The RFC
+specification handle the content of a lot of system databases, but do
+not handle DNS zones and DHCP configuration.&lt;/p&gt;
+
+&lt;p&gt;In &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu/Skolelinux&lt;/a&gt;,
+we would like to store information about users, SMB clients/hosts,
+filegroups, netgroups (users and hosts), DHCP and DNS configuration,
+and LTSP configuration in LDAP.  These objects have a lot in common,
+but with the current LDAP schemas it is not possible to have one
+object per entity.  For example, one need to have at least three LDAP
+objects for a given computer, one with the SMB related stuff, one with
+DNS information and another with DHCP information.  The schemas
+provided for DNS and DHCP are impossible to combine into one LDAP
+object.  In addition, it is impossible to implement quick queries for
+netgroup membership, because of the way NIS triples are implemented.
+It just do not scale.  I believe it is time for a few RFC
+specifications to cleam up this mess.&lt;/p&gt;
+
+&lt;p&gt;I would like to have one LDAP object representing each computer in
+the network, and this object can then keep the SMB (ie host key), DHCP
+(mac address/name) and DNS (name/IP address) settings in one place.
+It need to be efficently stored to make sure it scale well.&lt;/p&gt;
+
+&lt;p&gt;I would also like to have a quick way to map from a user or
+computer and to the net group this user or computer is a member.&lt;/p&gt;
+
+&lt;p&gt;Active Directory have done a better job than unix heads like myself
+in this regard, and the unix side need to catch up.  Time to start a
+new IETF work group?&lt;/p&gt;

+		<description>&lt;p&gt;I&#39;m sitting on the train going home from this weekends Debian
+Edu/Skolelinux development gathering.  I got a bit done tuning the
+desktop, and looked into the dynamic service location protocol
+implementation avahi.  It look like it could be useful for us.  Almost
+30 people participated, and I believe it was a great environment to
+get to know the Skolelinux system.  Walter Bender, involved in the
+development of the Sugar educational platform, presented his stuff and
+also helped me improve my OLPC installation.  He also showed me that
+his Turtle Art application can be used in standalone mode, and we
+agreed that I would help getting it packaged for Debian.  As a
+standalone application it would be great for Debian Edu.  We also
+tried to get the video conferencing working with two OLPCs, but that
+proved to be too hard for us.  The application seem to need more work
+before it is ready for me.  I look forward to getting home and relax
+now. :)&lt;/p&gt;

+		<description>&lt;p&gt;Where I work at the University of Oslo, one decision stand out as a
+very good one to form a long lived computer infrastructure.  It is the
+simple one, lost by many in todays computer industry: Standardize on
+open network protocols and open exchange/storage formats, not applications.
+Applications come and go, while protocols and files tend to stay, and
+thus one want to make it easy to change application and vendor, while
+avoiding conversion costs and locking users to a specific platform or
+application.&lt;/p&gt;
+
+&lt;p&gt;This approach make it possible to replace the client applications
+independently of the server applications.  One can even allow users to
+use several different applications as long as they handle the selected
+protocol and format.  In the normal case, only one client application
+is recommended and users only get help if they choose to use this
+application, but those that want to deviate from the easy path are not
+blocked from doing so.&lt;/p&gt;
+
+&lt;p&gt;It also allow us to replace the server side without forcing the
+users to replace their applications, and thus allow us to select the
+best server implementation at any moment, when scale and resouce
+requirements change.&lt;/p&gt;
+
+&lt;p&gt;I strongly recommend standardizing - on open network protocols and
+open formats, but I would never recommend standardizing on a single
+application that do not use open network protocol or open formats.&lt;/p&gt;
