public interface JaasAuthenticationCallbackHandler (Code)
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.
Handle the Callback. The
handle method will be called for every callback instance sent from the LoginContext. Meaning that The handle
method may be called multiple times for a given JaasAuthenticationCallbackHandler.
Parameters: callback - Parameters: auth - The Authentication object currently being authenticated. throws: IOException - throws: UnsupportedCallbackException -
