Amethyst 1.7.0.0 supervisor login issues

[John Richard Procter]

Issue:
Created a new supervisor through the webadmin.
Username and password are the same and I left email blank.
When I try and login the page refreshes as the login was unsuccessful.

Resolution:
Change the password to be all uppercase characters and add an email address for the supervisor.
Try and login again with the email address and password.
