<div id="banner">
    <span id="welcome_message"><?php echo getenv('HTTP_SM_USER')?></span>       
</div>

Answer 1

Have you tried to get the SM_USER header name instead of HTTP_SM_USER. Also check the value of the DisableUserNameVars parameter in the ACO that is being used. It should be either commented or set to No.
