Using ADSSecurity.DLL from an ASP.NET web service

[Gilligan Joy]

Hi all,

I'm trying to obtain a hex string security ID (SID) using ADsSecurity.DLL
from a web service. However, when the ADsSID.SetAs() method is invoked from
within the web service, a "page not found" error is generated in the browser
window. Impersonating using an administrator's account doesn't work.

I can obtain a hex string security ID without any difficulty using
ADsSecurity.DLL from a Windows Forms application running under an
administrator's account.

I have found code on the web for the .NET equivalent for obtaining the hex
string security ID (by using property "objectSID"), but it returns a blank
value.

Any help would be appreciated!

Thanks,
