hello,
i have installed rc1. It works good, but i have a problem with user registration with usernames include äöü.
E.g username ist "allgäuerpeter", registration and backlink are ok. Account is active,but the user cannot log in.
Note, in the mail the username is: allgäuerpeter. But also with username "allgäuerpeter" i cannot log in.

What can i do?

Thanks
Andreas
