[TYPO3-dev] Why are usernames converted to lowercase?

[Steffen Kamper]

Hi Peter,

i'm sry, but this is not a good way answer questions. Do you really 
think google help with this problem? Try it yourself and you'll see.

Also this is not a kind way as we are used in the community. So please 
try to be constructive.

@Jörg: if you look to TCA of BE_USER you'll find this eval:
'eval' => 'nospace,lower,unique,required'

try your luck to modify it and see if it works

$TCA['be_users']['columns']['username']['config']['eval'] = 
'nospace,unique,required';
