 /**
  * surfer has been authenticated
  *
  * This function copies user attributes in session storage area.
  *
  * Following named attributes from the provided array are copied in session storage area:
  * - $fields['id'] - id of the logged surfer
  * - $fields['nick_name'] - nick name of the logged surfer
  * - $fields['email'] - email address
  * - $fields['editor'] - preferred on-line editor
  * - $fields['capability'] - 'A'ssociate or 'M'ember or 'S'ubscriber or '?'
  * - $fields['phone_number'] - phone number (international format)
  *
  * We also remember the IP address of the authenticating workstation,
  * and the root path of the instance that has validated the surfer.
  *
  * @param array session attributes
  * @param boolean TRUE to remind date of last login in user record
