Your system, your rules, however...

Just because you *can* do something doesn't mean you *should* do it - 
and just because something is RFC compliant doesn't mean you should 
always implement it that way.

There are very few compelling arguments for supporting identical 
usernames differing only by case. One is some kind of legacy (unix) 
environment where you already have a lot of these... but I can't readily 
think of another (good one)...
