[CalendarServer-users] Unhandled error in XML directory service

[Carlos Valiente]

Hi! I set up a CalendarServer instance (version 4.1.1-dev) with an XML
directory service configured this way:

caldav.plist snippet:

    <key>DirectoryService</key>
    <dict>
      <key>type</key>
      <string>twistedcaldav.directory.xmlfile.XMLDirectoryService</string>

      <key>params</key>
      <dict>
        <key>xmlFile</key>
        <string>accounts.xml</string>
      </dict>
    </dict>

accounts.xml:

    <?xml version="1.0" encoding="utf-8"?>
    <!DOCTYPE accounts SYSTEM "accounts.dtd">

    <accounts realm="virutass.net">
      <user>
        <uid>admin</uid>
       <password>XXXX</password>
        <name>Super User</name>
      </user>
    </accounts>

When CalendarServer starts, I get the following error:

2012-08-28 20:00:24+0200 [-]

The problem goes away by adding a ``guid`` element under ``<user>``.

Is this the expected behaviour -- that the ``guid`` child of ``user``
is mandatory? In case it is, is it worth opening a Trac ticket?
