[mapguide-users] User re-authentication

[web]

Hi all,
I would like to know which way the login, session (username) are set in PHP. I want to give the availability to the use to reauthenticate with another account in my application.

I've seen it was normally $_SERVER['PHP_AUTH_USER'], but when I log myself with "Administrator" , "admin", I can't see this variable.

Where are user-session, set?
