FIX: Editing sample files to enable users to access additional sites without having to reauthenticate does not work in Forefront Unified Access Gateway 2010

View products that this article applies to.

Symptoms

You edit the WhlFiltSSO.ini and Sso.inc sample files in Microsoft Forefront Unified Access Gateway (UAG) 2010 Service Pack 1 (SP1) or a later version to implement cross-site single sign-on. You do this to enable users who log on to one Forefront UAG site to access additional Forefront UAG sites without having to reauthenticate. However, when a user tries to access additional Forefront UAG sites, the user must provide credentials to access the sites.
