Need Help Authentication Loses HttpContext??

We have both a custom data extension and a custom authentication extension for Reporting Services 2000.

Reports with one dataset work great, but reports with more than one dataset fail because the Authentication extension call GetUserInfo no longer has an HttpContext when the second dataset calls into it.

I've seen several people post this same problem on other forums but no answers. Documentation of an msdn article states "the security extension will always be loaded in the Report Server app domain" so I don't understand how we could lose the context.

Additionally, ALL samples of an authentication extension I've looked at have GetUserInfo coded the same way:




Code Snippet


Public Sub GetUserInfo(ByRef userIdentity As System.Security.Principal.IIdentity, ByRef userId As System.IntPtr) Implements Microsoft.ReportingServices.Interfaces.IAuthenticationExtension.GetUserInfo


If Not System.Web.HttpContext.Current Is Nothing _


AndAlso Not System.Web.HttpContext.Current.User Is Nothing Then

userIdentity = System.Web.HttpContext.Current.User.Identity

Else


userIdentity = Nothing

End If
userId = IntPtr.Zero

End Sub

Any help or insights would be GREATLY appreciated - thanks, Ken.
