Re: Can't get impersonation to work

Check out this article:

Your code will probably require FullTrust trust independently of the user
you impersonate.

Let me know if you still have problems after that.

I have a .Net application and one of my ASP pages exports a Crystal Reports
file to a network drive. The problem is that when Crystal exports the file,
it uses the ASPNET user account, which doesn't have access rights to the
network drive.

I want to impersonate the authenticated user when I do the export, but it
doesn't seem to work. When I run the app, FileMon shows that it is still
using ASPNET.

I have tried adding the <identity impersonate="true" userName="validuser"
password="validpass"/> to my web.config file, but that doesn't work
either. I did think I had this working yesterday, but today it doesn't
seem to be ?!?!

I have also tried the following code:

currentWindowsIdentity =
CType(User.Identity,System.Security.Principal.Wind owsIdentity)
impersonationcontext = currentWindowsIdentity.Impersonate()

ReportName.Export()

impersonationcontext.Undo()

This shows the impersonation elements to be the same as the authenticated
user, but the app still blows up and FileMon still shows ASPNET as the
user.

What am I doing wrong?!?!?!

THanks,
Ed
