指定了无效的DN语法 - Visual Studio错误

Question

我正在尝试制作一个Visual Studio程序，允许您将用户添加到Active Directory。每当我添加用户时，我都会收到错误＆＃34;指定了无效的DN语法＆＃34;。我不知道这个错误究竟意味着什么，谷歌搜索我知道这可能是一大堆事情。以下是相关代码：

            string UserName = txt_UserName.Text;
            string Department = ddl_Department.SelectedItem.ToString(); //The chosen OU
            string LDAPstring = "LDAP://OU=" + Department + ",DC=group0, DC=han";
            DirectoryEntry dirEntry = new DirectoryEntry(LDAPstring);

            //Make a USER Object
            DirectoryEntry newUser = dirEntry.Children.Add(UserName, "user");
            newUser.CommitChanges(); //User is made
            newUser.Properties["userprincipalname"].Add(txt_UserName.Text + "@group0.han");
            newUser.Properties["samaccountname"].Value = txt_UserName.Text;
            newUser.CommitChanges(); //User is given properties

Answer 1

如果你改变这一行，我认为你应该很好：

DirectoryEntry newUser = dirEntry.Children.Add(UserName, "user");

到此：

DirectoryEntry newUser = dirEntry.Children.Add("CN=" + UserName, "user");

此外，userPrincipalName并非多值。只需在其上设置值，就像设置sAMAccountName值一样。
