Browser Is Forced to Reauthenticate When Browsing Between Two Separate Passport Partner Sites (277761)

SYMPTOMS

When you go from one site to another for the first time, and both sites use Passport authentication, you are asked to reauthenticate to the second site. You must provide permission to provide information to the other site if you have not been there at least once during the currently logged on session.

After the first time you provide logon information to the second site, you are automatically signed in to the second site. However, the second site can perform a "forced logon", so that you have to log on again to reauthenticate.
