Problems with passport authentication

[Kathy]

Hi,
I am facing some problems while implementing passport authentication.
I have followed the following steps ...

1. Installed Passport SDK
2. Got the Key and installed
3. Set SiteID using admin tool

After all these, the Login page wouldn't come up on login.aspx page

In the EventLog, i get the following messages:
"Passport Manager configuration ok."
"Passport Manager process started successfully."

Code snippet:
Dim Passport As PassportIdentity
Passport = Page.User.Identity
If (Passport.GetFromNetworkServer) Then
Response.Redirect("http://localhost")
End If

But GetFromNetworkServer is always false.

Any thoughts on this ?
