如何找到ADUser的密码到期日期或密码到期之前的剩余天数？

Question

我有一个ADUsers列表,我想检查是否有任何用户的密码即将到期,但我找不到任何要检查的属性.

Answer 1

这应该可以找到每个用户密码到期之前的剩余时间:

private static TimeSpan GetTimeRemainingUntilPasswordExpiration(string domain, string userName)
{
    using (var userEntry = new System.DirectoryServices.DirectoryEntry(string.Format("WinNT://{0}/{1},user", domain, userName)))
    {
        var maxPasswordAge = (int)userEntry.Properties.Cast<System.DirectoryServices.PropertyValueCollection>().First(p => p.PropertyName == "MaxPasswordAge").Value;
        var passwordAge = (int)userEntry.Properties.Cast<System.DirectoryServices.PropertyValueCollection>().First(p => p.PropertyName == "PasswordAge").Value;
        return TimeSpan.FromSeconds(maxPasswordAge) - TimeSpan.FromSeconds(passwordAge);
    }
}

注意:您需要添加引用System.DirectoryServices.
