RadAsyncUpload Access to the path is denied when impersonating

[Chris Du]

Background info: when user upload a file the file is save to a folder on a shared network drive. I'm using the RadAsyncUpload and I'm getting an error when i'm impersonating an acct that have access to the folder.

Error on this line :  FileUpload_File.UploadedFiles.Item(0).SaveAs(FullFilePathName)


Error Msg: Access to the path is denied

Stack: at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.__Error.WinIOError() at System.IO.File.Move(String sourceFileName, String destFileName) at Telerik.Web.UI.AsyncUploadedFile.SaveAs(String fileName, Boolean overwrite) at Telerik.Web.UI.UploadedFile.SaveAs(String fileName) at xDefault.SaveFile()

I'm only getting this error when i'm impersonating

anyone have any idea why i'm having this issue?

Hi Chris,

Are you getting something like this? Probably the impersonated user doesn't have write permissions to the folder on the shared network drive. You can use the following code: 

private string GetWindowsIdentity()
{
    return (System.Security.Principal.WindowsIdentity.GetCurrent().Name);
}

to get identity passed from IIS. For more details please take a look at this link.

In addition be sure that the ASP.NET Impersonation Authentication is Enabled and configured correctly.

All the best,

Hi Chris,

Could you record a short video to see what permissions you give and to see how you configure the  Authentication in IIS? You can use this free software to create and share videos.
