Couple of good error codes to get started.  If you want to detect failure of ldap_add due to the record already existing, ldap_error == 0x44.  This means, you can do something like:

$r = ldap_add($ds, $dn, $info);
if (!$r) {
    if (ldap_errno($ds) == 0x44) {
         // Do something about it
    } else {
         // A real failure
    }
}

Similarly, on ldap_delete, you will get a 0x20 value (No Such Object) if you try to delete something that isn't there.
