This is the message I get when I try to login "Please enter a correct email
and password. Note that both fields may be case-sensitive."
I've changed my code a little in an effort to try to remedy my situation.
I'm really stuck on this. From what I can tell, it's passing the values to
the authenticate() method in my EmpBackend but it keeps saying password is
not valid. How do I pass the correct password value? Am I overlooking
something?
