Missing input form in create_poll.php when using RemoteUser env var
I use REMOTE_USER which is correctly set (LOG apache2 show this and a PHP test too) but create pool form is not displayed !
see attached screenshot : framadate-REMOTE_USER
And I do not understand where env VAR REMOTE_USER is read in the source code, it's just tested once to check it exist, but I do not see anywhere it's used :
create_poll.php:$useRemoteUser = USE_REMOTE_USER && isset($_SERVER['REMOTE_USER']);
many thanks for your help
