title: MySQL users: When localhost changed to %, I cannot login
body: <p>I am developing an app with MySQL. I have MySQL (XAMPP) running on my PC. All works fine but now I want to let other users from our network to login, but I found out that when I change user property "localhost" to % (any computer) I get access denied even with my own account.
  So, in the short, everytime I change "localhost" to "%" (any computer) I get "access denied". When switch back to localhost I can log easily.</p>
  
  <p>What is wrong please?
  Thank you</p>
