Case Sensitivity issue

Slight bug/issue

User gets their password wrong, and you get an log entry of :-

Authentication failure for {$username}

Which hits wordpress-soft and gives them 3 tries to login. (this is good)

User gets their password wrong while using different capitalisation of their username (users!!!), and you get an log entry of :-

Authentication attempt for unknown user {$username}

Which hits wordpress-hard and is an instant ban. (this is bad)

Any chance of an update to make the if statement case insensitive?

$msg .= (wp_cache_get($username, ‘userlogins’))
? “uthentication failure for {$username}”
: “uthentication attempt for unknown user {$username}”;

Thanks…
