Citrix Portal Login

Helllo there,

I need to make sure that people get challenged for a username and password when they access the Citrix Web Interface.

Whats happening now is that there credentials must be getting cached in the browser, today when they navigate to the Citrix Web URL it bypasses the challenge (using their domain credentials). I want to force them to enter their username and passowrd all the time at the Citrix Web Interface.

Thanks
