Have you ever wanted to make an asynchronous call but use the credentials of the user that is browsing

Hey,

method 3 uses protocol transition - thats ony available on Server 2003+ in 2003+ level AD domains.

Also the impersonation token you get from this technique cannot be used to access local resources (unless you run as SYSTEM). Remote resources can only be accessed using constrained delegation (with the 'any authentication protocol' option). fyi.

Dominick,

Thanks for this info. If you require these limitations to be lifted, you can use the LogonUser API from the first link referenced in the Additional Information.

Hi,

it was just a fyi. Method 3 will not work for the most cases.

...and LogonUser would require a password ;)
