SSO with SharePoint 2007

[=?Utf-8?B?TWF0cmFNNjUw?=]

We can maintain SSO (single sign on) between SharePoint 2003 and a third
party WebSSO provider. This is done by passing to the WebSSO provider the
authenticated domain user name and password, then creating a user context
with LogonUser, and returning control to the web server. IIS then passes the
user context to SharePoint 2003 allowing us to maintain SSO. Unfortunately
we can not do the same with SharePoint 2007.

Calling LogonUser to pass the user information to SharePoint 2007 causes the
web browser to hang indefinitely. If we skip calling LogonUser or leave the
username and password name fields blank, we get challenged for valid
credentials by both the WebSSO provider as well as SharePoint 2007
