AuthenticationProvider
=====================
Need to override authenticate and support methods
=====================
Authentication authenticate(Authentication authentication) throws AuthenticationException

authentication - the authentication request object
Returns:
a fully authenticated object including credentials. May return null if the AuthenticationProvider is unable to support authentication of the passed Authentication object. In such a case, the next AuthenticationProvider that supports the presented Authentication class will be tried.
Throws:
AuthenticationException - if authentication fails.
=====================
boolean supports(Class authentication)

Returns true if this AuthenticationProvider supports the indicated Authentication object.
Returning true does not guarantee an AuthenticationProvider will be able to authenticate the presented instance of the Authentication class. It simply indicates it can support closer evaluation of it. An AuthenticationProvider can still return null from the authenticate(Authentication) method to indicate another AuthenticationProvider should be tried.

Selection of an AuthenticationProvider capable of performing authentication is conducted at runtime the ProviderManager.
Parameters:
authentication -
Returns:
true if the implementation can more closely evaluate the Authentication class presented
