Would you care to elaborate on that please? I'm a bit surprised, at first
sight, you increase the possibilities a lot when you have to take into
account the case, making dictionary and brute force attacks that much more difficult. For each word, the possibilities are 2^L where L is the length of the word. Assuming the users do use random case within the password, how
is it not more secure than a case-insensitive password?

Unless the attacker knows that the system is case-insensitive, the mean time to break-in will be the same since they will still test passwords of all case.
