ldap_add(): Add: Object class violation error

When I try to add attribute to the OpenDS via PHP I get the following error:

ldap_add(): Add: Object class violation

Please help.

Here is my code

<?php
$ldapconfig['host'] = 'PC100';
$ldapconfig['port'] = 1389;
$ldapconfig['basedn'] = 'dc=company,dc=com';

$ds=ldap_connect($ldapconfig['host'], $ldapconfig['port']);

$password=1;
$username="cn=Directory Manager";

if ($bind=ldap_bind($ds, $username, $password)) {
  echo("Login correct");
  ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3); // IMPORTANT
  $dn = "cn=roshan1,dc=example,dc=com"; 
  //$newuser["objectclass"] = "inetOrgPerson"; 
  //$newuser["cn"] = "new1"; 
  //$newuser["sn"] = "user"; 

  $ldaprecord['cn'] = "roshan1";
  $ldaprecord['givenName'] = "mkljl";
  $ldaprecord['sn'] = "roshan";
  $ldaprecord['objectclass'] = "inetOrgPerson";    
  $ldaprecord['mail'] = "lkl@fh.com";
  $ldaprecord['mmmm'] = "77878";

  // add data to directory
  $r = ldap_add($ds, $dn, $ldaprecord);

} else {

  echo("Unable to bind to server.</br>");

}
?>

If I remove $ldaprecord['mmmm'] = "77878"; from the code it works fine. How can I add a new attribute like this?

Solution

Hmm, it looks like You are trying only to set objectclass to inetOrgPerson, but You have to set also other upper classes from which inetorgPerson is extending - that would be top and person maybe...

So:

$ldaprecord['cn'] = "roshan1";
$ldaprecord['givenName'] = "mkljl";
$ldaprecord['sn'] = "roshan";
$ldaprecord['objectclass'][0] = "top";
$ldaprecord['objectclass'][1] = "person";
$ldaprecord['objectclass'][2] = "inetOrgPerson";
$ldaprecord['mail'] = "lkl@fh.com";
$ldaprecord['mmmm'] = "77878";
