Please include a short example script in this report.

I can't reprocude this with my test scripts. If this still
happens with PHP 4.0.6, reopen. Check also your locale settings.

// Here is a function to translate all values of a multi-dimensional array to UTF8

function encoder ($array)
{
  while ( list ($key, $val) = each ($array) ) 
  {
    if (!is_array($val))
      $array[$key] = utf8_encode($val);
    else $array[$key] = encoder ($val);
  }	
  return $array;
}

//Here is a call where 
// - $conn_id is a valid connection ID
// - $dn is the dn of the object to add
// - $array is the array containing the values of the attributes indexed by name

$array = encoder($arr); 
ldap_add($conn_id, $dn, $array);

// this call fails 
// - if $array contains a special char (e.g ?, ?...) , thus returning SYNTAX ERROR
// - if $dn contains a special char (e.g ?, ?...) , thus returning No Such Object

What would the locale setting change? According to the docs, PHP have a UTF8 internal reprsentation of data...

Okay, does the ldap server support ldap v3?
If so, you should propably try to add this:

ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3)

--Jani

The problem turned out to be that the syntax for the
attribute was IA5, thus not allowing non-ASCII. We
should see if we can report more precise error messages
that includes which attribute was the problem.
