This script is copypasted (and modifyed for my system) from the manual, and reproduces the error on my system..

<?php
$ds=ldap_connect("iplanet.server.com");  // assuming the LDAP server is on this host

if ($ds) {
    // bind with appropriate dn to give update access
    $r=ldap_bind($ds,"cn=Directory Manager", "secret");

    // prepare data
    $info["cn"]="John Jones";
    $info["sn"]="Jones";
    $info["mail"]="jonj@here.and.now";
    $info["objectclass"]="person";

    // add data to directory
    $r=ldap_add($ds, "cn=John Jones, o=whitebird", $info);

    ldap_close($ds);
} else {
    echo "Unable to connect to LDAP server"; 
}
?>

This script generates the error somewhat like: Warning: LDAP: add operation could not be completed. in /home/leitet/public_html/Beta1/functions/func.inc.php on line 17

When I use a ldap_modify() call, it works, and the designated attribute I want to change is changed. But when I first use the function for updating the directory using ldap_modify() and then use the ldap_add() function, both fails giving: LDAP: modify operation could not be completed and LDAP: add operation could not be completed.

I have a "out of the box" php.ini. Have compiled LDAP support into php by using openldap, and connects to a Netscape Directory Server in order to try to update it..

The mentioned fuctions follows:

// Update number of entries
function update_number_of_entries($ds,$ldap_default_path)
{
  $data1 = "nsnumdomains";
  $aa="(objectClass=*)";
  $sr=ldap_read($ds, $ldap_default_path, $aa);
  $entry = ldap_first_entry($ds, $sr);
  $value = ldap_get_values($ds, $entry, $data1);
  $value[0]++;
  $data[nsnumdomains] = $value[0];
  ldap_modify($ds,$ldap_default_path,$data);
}
