 * This exception indicates that SASL authentication has failed. The error message
 * in the exception indicates the actual cause of failure.
 * 

* SASL authentication failures typically indicate invalid credentials, but * could also include other failures specific to the SASL mechanism used * for authentication. *

*

Note:If {@link SaslServer#evaluateResponse(byte[])} throws this exception during * authentication, the message from the exception will be sent to clients in the SaslAuthenticate * response. Custom {@link SaslServer} implementations may throw this exception in order to * provide custom error messages to clients, but should take care not to include any * security-critical information in the message that should not be leaked to unauthenticated clients. *
