XP user authentication

[Avi]

Folks,

Given the following function signature: bool AutheticateUser(string uid,
string pwd);

Can anyone tell me which .Net class.function API can I use to return
true/false if the password passes the XP authentication for a particular
machine / AD for the uid?

Many thanks,
Avi

There is no .NET function for this yet, but you can call the LogonUser API
via pinvoke. The code sample in the MSDN documentation for
WindowsImpersonationContext has a nice sample.

That type of authentication is implemented in the below MS KB article:
