Property Value

Reference to an FPCDomainNameSet collection that contains the domain names used for SSO.


This property is read-only. Domain names can be added and removed by calling the Add and Remove methods of the FPCDomainNameSet collection retrieved (the IFPCDomainNameSet interface retrieved in C++).

This property is applicable only if the SSOEnabled property is set to True (VARIANT_TRUE in C++) and the Web listener is configured to use forms-based authentication.

After a user is authenticated for access to a Web site that matches a domain name specified in this property, the user can access any other URL containing a matching domain name through the Web listener without being prompted to present credentials again. In particular, users can move safely from one application to another, without having to reauthenticate. For example, an authenticated user can move securely and seamlessly from Outlook Web Access to a SharePoint site by clicking a link in an e-mail, without reauthenticating.
