Description (partial)


SSO for RDP & RDP2 plugins doesn't work if user launches RDP session from browser favorites/bookmarks.


The RDP bookmark is configured for SSO (csco_sso=1).
Through webvpn portal end user launches RDP plugin then saves this RDP session as a favorite in their IE Favorites or Firefox Bookmarks.  After logging out of webvpn when end user clicks on the favorite/bookmark link they get directed to the ASA portal to login.  Upon login to webvpn they are directed to the RDP Server but they must authenticate at the RDP server login screen; SSO fails.
