title: Open Directory Service
...

The Open Directory directory service provides principal information that
is obtained using Apple's Open Directory service.

Open Directory provides principal information for users, groups,
locations, and resources.

For more information about configuring Open Directory and running Open
Directory services, see Apple's [Open Directory
Administration](http://images.apple.com/server/macosx/docs/Open_Directory_Admin_v10.6.pdf)
document.

Configuring the Calendar Server
===============================

The full name of the service is
`twistedcaldav.directory.appleopendirectory.OpenDirectoryService` and
the service takes a `node` parameter which contains the name of the
directory node to bind to.

For example:

    <!-- Open Directory Service -->
    <key>DirectoryService</key>
    <dict>
      <key>type</key>
      <string>twistedcaldav.directory.appleopendirectory.OpenDirectoryService</string>

      <key>params</key>
      <dict>
        <key>node</key>
        <string>/Search</string>
      </dict>
    </dict>

The special Open Directory node `/Search` causes the server to use the
default directory search path that the host system the server is running
on is configured to use. To bind to a specific LDAP service, a node in
the form `/LDAPv3/ldapserver.example.com` may be specified.
