How to convert email address to username?

[Richard Frovarp]

JS on the login page can be a way to signal to users if you want them
to learn to not use it because other systems break. It will also
frequently work on systems that don't have a proper transform option
(just as a general FYI).

The proper way to do it is with shibboleth.authn.Password.Transforms
property on the server side:
