无法使用DirectoryEntry设置密码.在AD中使用ASP创建用户时调用.NET C#

Question

Web应用程序正在从人员管理页面创建用户，该页面又将用户添加到Active Directory中。以下是执行此操作的代码：

DirectoryEntry Folder = new DirectoryEntry("LDAP://XXXX.com/CN=ContainerName, DC=XXXX, DC=com", admin, adminPwd, AuthenticationTypes.None);
    if (Folder.SchemaEntry.Name == "container")
    {
        DirectoryEntry user = Folder.Children.Add("CN=" + txtFirstname.Text + " " + txtLastname.Text, "User");
        if (DirectoryEntry.Exists(user.Path))
        {
            // Error Msg Here
        }
        else
        {
            // Required attributes
            if (txtFirstname.Text != "" && txtLastname.Text != "") { user.Properties["sAMAccountName"].Value = txtFirstname.Text.ToLower() + "." + txtLastname.Text.ToLower(); }
            if (txtFirstname.Text + " " + txtLastname.Text != "") { user.Properties["cn"].Value = txtFirstname.Text + " " + txtLastname.Text; }
            // More controls to populate Optional AD attributes.  Not entered to conserve space.  The code works however.
            user.CommitChanges();
            int val = (int)user.Properties["userAccountControl"].Value;
            user.Properties["userAccountControl"].Value = val & ~0x2;
            user.Properties["pwdLastSet"].Value = 0;
            user.CommitChanges();
            user.Invoke("SetPassword", new object[] { "SuperSecretPassword" });
            user.CommitChanges();
        }

问题是，在创建帐户后，invoke方法无法设置密码。每次尝试设置密码都会在catch语句中返回此错误：

System.Reflection.TargetInvocationException was caught
HResult=-2146232828
Message=Exception has been thrown by the target of an invocation.
Source=System.DirectoryServices
StackTrace:

   at Personnel_Govt.CreateUser() in c:inetpubwwwrootTestingFolderPersonnelAddGovt.aspx.cs:line 148
   at Personnel_Govt.btnSubmit_Click(Object sender, EventArgs e) in c:inetpubwwwrootTestingFolderPersonnelAddGovt.aspx.cs:line 95
InnerException: System.UnauthorizedAccessException
   HResult=-2147024891
   Message=One or more input parameters are invalid
   Source=Active Directory
   InnerException: 

如果在创建帐户后在AD中手动设置密码并选中"需要重置"，则该密码将起作用。

为什么设置密码的方法失败了？？？

问题解决了。显然，Internet信息服务（IIS_IUSRS）帐户没有设置Active directory密码的权限。它可以更改密码，但不能设置密码。

允许ASP。NET页面设置一个AD密码上创建帐户，我必须运行"Active Directory用户和计算机"，右键单击域，选择"委派控制"。这将打开一个向导，允许您授予帐户IIS_IUSRS对AD进行更改的权限。
