Windows Vista users verification

Question

hi! I want to verify that given username/password pair is a valid windows vista account using c#.

Answer 1

You could use a PInvoke to LogonUser or, alternatively, use System.Diagnostics.Process to start a new process with a specified username/password and see if it succeeds.

Answer 2

Maybe the System.Security namespace could help you

Answer 3

// create a "principal context" - e.g. your domain (could be machine, too)
PrincipalContext pc = new PrincipalContext(ContextType.Domain, "YOURDOMAIN");

// validate the credentials
bool isValid = pc.ValidateCredentials("myuser", "mypassword")

Easy peasy
