+<p>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.</p>
+
+<p>In <a href="http://www.skolelinux.org/">Debian Edu/Skolelinux</a>,
+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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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?</p>

+<p>I'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. :)</p>
