Bug #11766641: 59792: BIN/MYSQL -UUNKNOWN -PUNKNOWN

Browse Source 
.-> USING PASSWORD: NO

The server was always setting the flag for using password to NO and
then relying on the server authentication plugin to update it if it uses
a password.
This creates compatibility problems with 5.1 when rejecting a 
nonexistent user login.
Set the default for the password supplied flag for non-existing users
as the default plugin (native password authentication) would do it
for compatibility reasons.
Test case added.
federated.result updated with the correct error message.
