>Hello Everybody.
>
>I got some problems with impersonation.
>
>I have created a asp.net intranet site. The short of it is that the end user gets a grid displayed with pdf files. The pdf files are located on another sever behind locked security to which the enduser has no directly access.
>
>When the user clicks on a file in the grid the site should display the pdf file in an embeded pdf viewer on that page. In order to accomplish this i use impersonation in the code-behind secion.

>Using impersonationContext As New WindowsImpersonationContextFacade()
>   Me.ShowPdf1.FilePath = c_TempFilePath
>End Using

>(Note: this code is used from here with some modifications to fit my purposes. I also know this works because i use the exact same code in a vb.net app to access the same files successfully.)
>
>As long as i am testing this (domain admin with rights to that repository) it works fine - so i know the basic loading of the file works. However, for the enduser it does not work. They don't get an error, but the pdf does not display.
>
>My assumption is that the file does not actually get loaded in the behind-code but that code only passes the info to the client and the client loads the file.
>
>If that is true, that would explain the failure as the client does not have the read right to the repository and the impersonation is already gone.

>As always - thank you for your great help!

Just glanced at this but it looks as if you are only using impersonation whilst setting a property - not whilst ASP.NET needs to actually access the file ?
