Single sign on in ASP.NET

I have several .NET web applications in the co intranet. Currently, every
application has its own login screen to authentication and the
authentication is Forms Authentication with Active Directory. Now, I want to
by-pass the login screen but still want to use AD to have authentication. My
question is can I get the logged in username and password from windows and
proceed the AD authentication when user start the application.

In an intRAnet situation, where all (applicable) servers and clients run Win
dows,
you can use the windows-login to automatically get access to your site.
I've never done it (yet) so I can't give more details, but I think you shoul
d look
at the security tab in the IIS properties for the site(s).

If user is there in AD, then you can use integrated windows authentication.
Using user.Identity.Name(), you can get the username of the loged on user.

You may also have to turn on impersonation if your using this method. This m
ake sure users are not authenticated as the aspnet user, instead ,their netw
ork credentials are use.

Oh, I forgot to mention, Microsoft has already addressed this issue using th
e MS Passport. You might want to take a look at that. Download the Passport
SDK and work from there
