BI 4.0 and SSO via Token Passing

Hello,

Has anyone been able to create an .net aspx page to logon to BI 4.0 using token.

Something like this in XIR2

--->

Set SessionManager = Server.CreateObject("CrystalEnterprise.SessionMgr")

Set Sess = SessionManager.Logon(UserID, Password, CMS, Authorization)

Thanks
