Impersonation - using Impersonate with NewCredentials

[frankiefrank]

Hello,

I'm trying to implement impersonation.

When I use LogonUser with LogonSessionTyp e.Network I get a token which I pass into the WindowsIdentity constructor. That seems to work - I get an identity with the expected name.

However, when I use LogonSessionTyp e.NewCredential s and afterwards do DuplicateToken (to get the SecurityImperso nation token)
the WindowsIdentity object I create seems to still be my own identity.

Impersonate on that identity doesn't change the current WindowsIdentity .

Is there something I'm missing?

thanks,
Frankie
