[otrs] Database access denied for user "root" on installing 2.2.1Win32

Have you tried using blank password for user root on installing OTRS database?

Yes, I just tried and it works **without** password. I was deceived by the red remark next to the empty field, which suggested me to enter a password. Why does it say I should enter a password, when I shouldn't actually? Funny. Thank you! Luigi
