User Authentication Experiences for P4S 2010
There are three potential authentication experiences for users working with Web Part pages that contain mashups or apps using Presto Add-On for SharePoint (P4S) 2010. From best experience to worst, these are:
Full Single Sign-On: with this experience, a user logs into
SharePoint. Their
SharePoint credentials are used without any additional login challenges to authenticate with
Presto Servers for any mashups or apps the user may work with in Web Part pages.
Initial Challenge Only: this provides a partial SSO experience limiting login challenges to a single challenge for the first mashup or app that a user encounters in a Web Part page. In addition to logging in with
SharePoint, a user must login with
Presto Servers once during a session in
SharePoint (a browser session). Each new session in
SharePoint may require this initial login to
Presto.
All Challenges: no authentication information is shared between
SharePoint and Presto with this design. Users must login with
Presto Servers for
every mashup or app that requires authentication. Obviously, this is the least user-friendly experience.
