public abstract class AuthProvider extends Provider
While callers may invoke login directly,
the provider may also invoke login on behalf of callers
if it determines that a login must be performed
prior to certain operations.

The provider relies on a CallbackHandler
to obtain authentication information from the caller
(a PIN, for example). If the caller passes a null
handler to this method, the provider uses the handler set in the
setCallbackHandler method.
If no handler was set in that method, the provider queries the
auth.login.defaultCallbackHandler security property
for the fully qualified class name of a default handler implementation.
If the security property is not set,
the provider is assumed to have alternative means
for obtaining authentication information.

principals/credentials used for authentication,
or may be populated with additional principals/credentials
after successful authentication has completed.

CallbackHandler.
The provider uses this handler if one is not passed to the
login method. The provider also uses this handler
if it invokes login on behalf of callers.
In either case if a handler is not set via this method,
the provider queries the
auth.login.defaultCallbackHandler security property
for the fully qualified class name of a default handler implementation.
If the security property is not set,
the provider is assumed to have alternative means
for obtaining authentication information.
