See the following code from the QueryHome, what you need is random number generator for the given length -

function poweredby_alphanum($length)
{
  $characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'; //<You can set any string here>
  $charactersLength = strlen($characters);
  $randomString = '';
  for ($i = 0; $i < $length; $i++) {
    $randomString .= $characters[mt_rand(0, $charactersLength - 1)];
  }

  return $randomString;
}

I'm trying to pull the password policy response message from ldap_bind() method: password is expiring, password expired etc.

While checking the packet content from OpenLDAP after ldap_bind() request, with Wireshark, there is a control hooked to the ldap_bind() response, were the message code and message text about password expiration is, but I can't manage to parse that message from response.

I set the password policy request server control before the bind with ldap_set_option(). Any workaround or what am I doing wrong?
