/**
 * This page may simply add the objectClass and take you back to the edit page,
 * but, in one condition it may prompt the user for input. That condition is this:
 *
 *    If the user has requested to add an objectClass that requires a set of
 *    attributes with 1 or more not defined by the object. In that case, we will
 *    present a form for the user to add those attributes to the object.
 *
 * Variables that come in as REQUEST vars:
 *  - dn (rawurlencoded)
 *  - new_oclass
 *
 * @package phpLDAPadmin
 * @todo If an attribute expects a DN, show the dn browser.
