 128 For command line interface, download the files, put them near your Taskwarrior
 129 configuration files, and add that to your Taskwarrior configuration:
 130 <pre>
 131 taskd.certificate=/path/to/<?php echo $ldap_user; ?>.cert.pem
 132 taskd.key=/path/to/<?php echo $ldap_user; ?>.key.pem

 138     echo "# taskd.credentials=$org/$user/$key\n";
 139   }
 140 } else { ?>
 141 taskd.credentials=<?php echo $entries[0][0]; ?>/<?php echo $entries[0][1]; ?>/<?php echo $entries[0][2]; ?>
 142 <?php } ?>
 143 taskd.ca=/path/to/ca.cert.pem
 144 </pre>
 145 For Mirakel, download and import the file:
 146 <ul>
 147 <?php
 148 foreach ($entries as $entry) {
 149   list($org, $user, $key) = $entry;
 150   echo '<li><a href="?file=mirakel&key='.$key.'">' . $user . '.mirakel</a></li>';
 151 }
