Username Case-Sensitive, Login impossible

[chrigiboy]

Hello,
first, i like roundcube really. But, i got a problem.
Roundcube will create new users at Table users. If the user use Max@smith.tld for his first login, he can't login again with max@smith.tld. Also when he login with max@smith.tld, he can't login with MaX@SmItH.TlD again. Until you change the stored username.
What should i do?

check the main config file, there is an option to convert usernames to lowercase, then all you need to do is make sure any already in your db are in lowercase.
