OK, I will go back and reread... My understanding was that SSL aka https was taking care of the credential checking using, in our case, Active Directory user entries - and that PHP was just grabbing the UID from that source - for instance, what I do is: //grab the logged on user, depending on whether they logged on with the domain prepended if(substr_count($_SERVER['REMOTE_USER'],"\\") != 0) { //the logon has a domain prepended before the 'actual' UID list($logged_on_domain, $logged_on_user) = split('\\\\', $_SERVER['REMOTE_USER']); //grab the logged on user off the IIS server variable/s, and split off the (presumed) "[domain]\" portion and essentially discard <--NOTE USE OF FOUR(4)backslashes as needs to be *double escaped* } else { //no domain (assume) prepended before the back slash, so just the 'actual' UID $logged_on_user = $_SERVER['REMOTE_USER']; }; I can set $_SERVER['REMOTE_USER'] = 'baddomain\baduser' of course - but when I return to the secure page the user's browser cache (?) has reset $_SERVER['REMOTE_USER'] to be their previously logged on user name - so they are still logged in... So maybe my "logging off" question is not really PHP-specific? Hmmm.... I will go back and reread various pages (paper and online) with your suggestion/s as the context - so thank you...
