Hello List,

ok, now, with some modification of lib/ldap.php i am able to add new
ldap entries with a unique uid, constructed from givenname, sn and
date. I know this code is crap, but unfortunately it is the best I was
able to accomplish :) I have also constructed the cn field from
givenname and sn, and used a 'name' composite field for display in the
web frontend.

here are the changes I have made to the lib/ldap.php


function addObject($attributes)
  if (empty($attributes['dn'])) {
       return PEAR::raiseError('Tried to add an object with no dn:
		 [' . serialize($attributes) . '].');
         } elseif (empty($this->_params['objectclass'])) {
             return PEAR::raiseError('Tried to add an object with no 
objectclass: [' . serialize($attributes) . '].');

// Construct uid from givenname, sn and date

$uid = $attributes['givenName'] . $attributes['sn'] .  date("dmyG");
$attributes['uid'] = $uid;

// Construct new dn from uid and root

$dn = "uid=" . $uid . "," . $this->_params['root'];

// Construct new cn from givenname and sn

$attributes['cn'] = $attributes['givenName'] . " " . $attributes['sn'];

-->snip end

The new ldap entries are created properly, but there is one problem 
left. After adding, a search for the entry is performed. Because the
search code hase no knowledge of my self-generated uid it always 
responds with an error message stating that the entry could not be 
found. I need a way to inject my uid back to the attributes form the
conf/sources.php ore directly into the search code.

Can someone help me with this task ? Is this possible ?

best regards
