<h2>1. Defining upload columns<br>
</h2>
If you want to support account creation via file upload you have to
define columns in the CSV file.<br>
Each column has an non-translated identifier, a description, help entry
and several other values.<br>
<br>
The upload columns are specified with <span style="font-weight: bold;">get_uploadColumns()</span>
or <span style="font-weight: bold;">meta['upload_columns']</span>.<br>
<br>
<span style="font-weight: bold; text-decoration: underline;">Example:</span><br
style="font-weight: bold; text-decoration: underline;">
<br>
The <span style="font-style: italic;">ieee802Device</span>
module has only one attribute and therefore one column: the MAC address.<br>
<br>

<h2>2. Building the accounts<br>
</h2>
When the user has uploaded the CSV file the modules have to transform
the input data to LDAP accounts.<br>
<br>
This is done with <span style="font-weight: bold;">build_uploadAccounts()</span>.
The function gets the input data and a list of LDAP accounts as
parameter.<br>
<br>
<span style="font-weight: bold; text-decoration: underline;">Example:</span><br
style="font-weight: bold; text-decoration: underline;">
<br>
The <span style="font-style: italic;">ieee802Device</span>
module has only one LDAP attribute - <span style="font-style: italic;">'macAddress'</span>
- and the <span style="font-style: italic;">'ieee802Device'</span>
objectClass which is added to all accounts.<br>
<br>
<table style="width: 100%; text-align: left;" class="mod-code"
border="0" cellpadding="2" cellspacing="2">
