title: Magento - Display Error/Notice on Login Page
body: <p>I am writing a module to deny admin users access unless coming from a specific IP. I am hooking into the admin successful login event, checking their IP against an array of IPs and if the admin user's IP is not in the list I am logging them out, and redirecting them back to the admin login page.</p>
  
  <p>My question is.... </p>
  
  <p>how do I set a message on the login page similar to "Incorrect Password"?</p>
  
  <p>Any snippets or ideas are greatly appreciated!</p>
  
  <p>Thank you!</p>
