GUACAMOLE-1152: Correctly differentiate between client errors and server errors.
By definition, a client error is not an internal error, but an
intentional refusal of the server to handle a malformed or otherwise
invalid request. These should not be handled in the same way as server
errors which unexpectedly block processing of a request and should be
corrected by an administrator.
In the case of GUACAMOLE-1152, client errors should not be ignored even
if failures are explicitly configured as tolerated for the associated
authentication provider.
