username is case sensitive

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create an account with a capitol letter in the username
2. post something on the microblogging secion (make a tweet)
3. try to view the feed

the code that generates the feed converts your username to lowercase making
it impossible to get to you feed no matter how you type it in the url.

The easy solution is to just change the code to use the case in the url
instead of using .lower() but I think the site should convert the username
to lowercase everywhere there is a comparison or matching algorith so that
you can log in without worrying about case sensitivity etc.

My webhost is webfactional. And I'm using pinax 0.5.1 (though it's very
heavily modified)

oops sorry I should have explained the patch... it doesn't deal with the feeds 
that I
mentioned in the bug report.

it allows users to login without worrying about the capitolization of their 
username
(which shouldn't be an issue since it uses a case insensitive lookup when it 
checks
for a username's availability on signup)... I solved the feed issue by changing 
the
username lookup to username__iexact like I did in this patch

Hello,

I am looking for a solution to this problem as well, I used you patch but then 
when a user types in an invalid 
username for login I get a django error isntead of a form validation error 
"user password incorrect".
Do you by chance have a fix for this?

just put the username__iexact  line in a try block and catch the django error 
like so:

try:
    attemptUser = User.objects.get(username__iexact=self.cleaned_data["username"]
    cleanUsername = attemptUser.username
except User.DoesNotExist:
    # if it's not a real username, just let the form return as expected
    cleanUsername = self.cleaned_data["username"]

user = authenticate(username=cleanUsername, 
password=self.cleaned_data["password"])
