Exception when calling FindByBadPasswordAttempt

Question

I'm trying the last time when my windows password was written incorrect. And to do it I use UserPrincipalSearcher:

PrincipalContext pc = new PrincipalContext(ContextType.Machine);
var v = UserPrincipal.FindByBadPasswordAttempt(pc, DateTime.Now, MatchType.LessThan);

But I get NotSupported exception in the second line of code. What is the problem?

Can you show the complete stack trace? – Jon Skeet Dec 19 '13 at 06:57 — Jon Skeet, Dec 19 '13 at 06:57

The method expects a date in UTC format. Although not noted in the help files, I would imagine that a wrong date format can be a reason for this exception.

Try to pass DateTime.UtcNow instead of just DateTime.Now.

What happens if you try `UserPrincipal.Current.LastBadPasswordAttempt`? – nvoigt Dec 23 '13 at 10:39
