For command line interface, download the files, put them near your Taskwarrior
configuration files, and add that to your Taskwarrior configuration:
<pre>
taskd.certificate=/path/to/<?php echo $ldap_user; ?>.cert.pem
taskd.key=/path/to/<?php echo $ldap_user; ?>.key.pem
taskd.server=<?php echo $host ."\n"; ?>
<?php if (count($entries) > 1) {
echo "# Chose one of them\n";
foreach($entries as $entry) {
list($org, $user, $key) = $entry;
echo "# taskd.credentials=$org/$user/$key\n";
}
} else { ?>
taskd.credentials=<?php echo $entries[0][0]; ?>/<?php echo $entries[0][1]; ?>/<?php echo $entries[0][2]; ?>
<?php } ?>
taskd.ca=/path/to/ca.cert.pem
</pre>
For Mirakel, download and import the file:
<ul>
<?php
foreach ($entries as $entry) {
list($org, $user, $key) = $entry;
echo '<li><a href="?file=mirakel&key='.$key.'">' . $user . '.mirakel</a></li>';
}
?>
</ul>
