Class Overview
The JaasAuthenticationCallbackHandler is similar to the
javax.security.auth.callback.CallbackHandler interface in that it defines a
handle method. The JaasAuthenticationCallbackHandler is only asked to
handle one Callback instance at at time rather than an array of all
Callbacks, as the javax... CallbackHandler defines.
Before a JaasAuthenticationCallbackHandler is asked to 'handle' any
callbacks, it is first passed the Authentication object that the login
attempt is for. NOTE: The Authentication object has not been
'authenticated' yet.
Public Methods
