使用LDAP和C#设置Active Directory帐户过期

Question

我想将新用户帐户设置为在创建后的90天内到期.这是我创建用户并设置所有内容的代码.一切正常,除了我试图将其设置为过期的最后一个块.

            DirectoryEntry newUser = dirEntry.Children.Add("CN=" + cnUser, "user");
            newUser.Properties["samAccountName"].Value = cnUser;
            newUser.Properties["userPrincipalName"].Value = cnUser;
            newUser.Properties["pwdLastSet"].Value = 0;
            newUser.CommitChanges();

            //Changes Password
            String passwrd = userPassword.ToString();
            newUser.Invoke("SetPassword", new object[] { passwrd });
            newUser.CommitChanges();

            //Sets User Account to Change Passowrd on new login
            newUser.Properties["pwdLastSet"].Value = 0;
            newUser.CommitChanges();

            //Enables account
            newUser.Properties["userAccountControl"].Value = (int)newUser.Properties["userAccountControl"].Value & ~0x2;
            newUser.CommitChanges();

            //Set the account to expire in 90 days
            var dt1 = DateTime.Today.AddDays(90);
            newUser.Properties["accountExpires"].Value = dt1.ToFileTime().ToString();
            newUser.CommitChanges();

关于如何开展工作的任何建议？

谢谢

Answer 1

请参阅有关此字段的文档.你需要将其转换为"滴答声" -

the number of 100-nanosecond intervals since January 1, 1601 (UTC). A value of 0 or 0x7FFFFFFFFFFFFFFF (9223372036854775807) indicates that the account never expires.

new DateTime(DateTime.UtcNow.AddDays(90).Ticks - new DateTime(1601, 1, 1).Ticks) 将为您提供正确和准确的价值.

您可以通过从上面的表达式获取值并执行来检查您的工作(手动):

w32tm.exe /ntte 130149277684873234

以上命令的结果对我来说是

150635 17:42:48.4873234 - 6/5/2013 12:42:48 PM

或者你可以这样做：

DateTime expire = System.DateTime.Now.AddDays(90);
newUser.Properties["accountExpires"].Value = Convert.ToString((Int64)expire.ToFileTime());
newUser.CommitChanges();

这比弄乱蜱虫和所有其他东西更容易处理
