  <p><b>Network of LDAP servers</b></p>
32
    <p>In the distributed network of Metacat servers, network of LDAP servers
33
      is implemented as a distributed storage of Metacat's users.
34
      Any Metacat instance running on particular site is configured to use 
35
      certain LDAP instance both usually running on the same host.
36
      Several Metacat instances can use one LDAP instance. </p>

41
      The distributed scheme of LDAP servers represents a hierarchy of nodes
42
      where in the leaves are the particular users used by the Metacat servers 
43
      for authentication.
44
      <br>
45
      The LDAP tree starts from the root context for the Knowledge 
46
      Network of Biocomplexity.:
47
      <pre>      dc=ecoinformatics,dc=org </pre>
48
      The nodes on the second level represent the subtrees of the major Metacat
49
      sites such as NCEAS, LTER, etc.:  </p>
50
<pre>
51
      o=NCEAS,dc=ecoinformatics,dc=org <br>
52
      or <br>
53
      o=LTER,dc=ecoinformatics,dc=org </pre>
54

    
55
      Look at the example for the
56
<a target="_top" href="entries-init.ldif">initial entries of KNB main tree</a>
57
      . <br><br>
58

    
59
      The third level contains the nodes of the particular users and groups.
60
      Users can be organized in groups. This allow Metacat to control access 
61
      to a group of users.

95
      Any LDAP subtree can reside on remote site. In that case the main tree holds
96
      referrals to all remotely running LDAP servers.
