I'm setting up WPC for anonymous access. For this reason a role was created and WPC navigation is attached to it with an external connector. This role is added to the Guest user.
The Guest user is accessing the page and is able to see the WPC navigation, but in the content area where the web page should be displayed a Login window appears instead. Permissions have been assigned correspondingly to SAP NW Library (http://help.sap.com/saphelp_nw2004s/helpdata/en/47/1da38afe214405e10000000a1553f6/frameset.htm).
