Hi Matthew,

I had a hunch it may be client side so thank you for confirming. How would
you make the server react in the correct way to that though? Or could you
at least point me in the right direction?

For example if I attempt on Windows I can set both of these things but
whenever I actually attempt the authentication the server just states that
the login was incorrect.

Kind regards,

Connor
