Case in-sensitive email addresses

[Dave Lawrence]

We have had some complaints about the way Bugzilla handles login_names
in the database through channel partners as well as bug reports.
Currently it seems that bugzilla accepts Dkl at Redhat.Com and
dkl at redhat.com as 2 separate accounts even though they are both the same
real email address. Looking at the CVS code this looks to be the same
now also. Should we be lowercasing the email address when a new user is
created and then lowercase values before comparing them to the
login_name field such as confirm_login? Is there already a bug report
for something like this? I was unable to find one at first glance in
b.m.o. I think this has been discussed before but not sure what opinions
came from it.

Thanks
