forgottenPassword LDAP attributes

[JasonEverling]

In current master and previous builds, within this page below, it does not honor 'select' type attributes, others also more than likely. It is also not letting the user override "required" and the max length attribute since they are set to hard coded values.

<input type="select"> would not be valid, it should create <select>....</select> for each select type field.
