No indication in Artifactory login page (UI) that the user has been locked out

when a user is being locked out after a few failed login attempts there is no indication in the login page that the user is locked and when clicking on the "Login" button nothing happens.

Steps to reproduce:

1. Create a user in Artifactory
2. Enable "Lock User After Exceeding Max Failed Login Attempts" option in Artifactory security configuration
3. Issue a few failed login attempts with different password
4. notice that once the user is being locked there is no indication about it
