Setting up IT Shop authentication for SSO and manual logon

Hi all,

I'm not sure if this can be done or not, so any advice is welcome.

My customer has their IT shop set up so that they seamlessly go into IT shop as the Windows authenticated account.

But they have said "what can I do if I want to change the user that I am logged in as?  How can I also log in manually?"

I have run the WebDesignerConfigFileEditor and set

1. Primary Authentication Module  --> ADSAccount (Rolebased)
2. Secondary Module --> ADSAccount

thinking that they could login automatically, logout and then login manually.   But it seems as if the WebApp automatically logs them back in again.

Is there any configuration that I need to make to IIS to enable the above config to work, or is it just an inompatible set of requirements ?

Thanks

Jon.
