Handle usernames in a case-insensitive manner

Hi,

If my username is “Bob”, I can login to WordPress using “bob”, “BOB”, “bOb”…
Right now, a failed login attempts using the right username is treated as an hard error instead of a soft one if the case of the entered username / email address does not match the case of the one stored in database.

Also:
– Is there a public repository to which I can send pull requests? I’ve found https://github.com/invisnet/wp-fail2ban-lts, but it seems outdated.
– Can you set me as translation editor for French language? I’ve uploaded translations but can’t validate them.

Thank you!
