DirectoryEntries.Find：＆QUOT;一个无效的dn语法已指定＆QUOT; [英] DirectoryEntries.Find: "An invalid dn syntax has been specified"

问题描述

我试图找出在当前域中的用户。在code是这样的：

I'm trying to find a user in the current domain. The code is this:

DirectoryEntry domain = new DirectoryEntry("LDAP://CN-Users, DC=" + Environment.UserDomainName);
            DirectoryEntries entries = domain.Children;
            try
            {
                // The following line causes the exception
                DirectoryEntry user = entries.Find("(&(objectCategory=user)(cn=" + userName + "))", ActiveDirectoryEntryType.User.TypeName);
                user.DeleteTree();
                user.CommitChanges();
            }
            catch
            {}

我得到一个错误：

I'm getting an error:

An invalid dn syntax has been specified.

我也试过以下code，并得到了同样的错误：

I also tried the following code and got the same error:

DirectoryEntry user = entries.Find(userName, ActiveDirectoryEntryType.User.TypeName);

我无法找到有关的帮助文件的正确语法的信息。有谁知道如何做到这一点？

I could not find information about the proper syntax in the help files. Does anyone know how this is done?

推荐答案

您在本statemet错误：

You have an error in this statemet:

DirectoryEntry domain = new DirectoryEntry("LDAP://CN-Users, DC=" + Environment.UserDomainName);

我几乎可以肯定，它应该是： LDAP：// CN =用户​​， instaed 的LDAP：// CN-用户，

I almost sure that it should be: LDAP://CN=Users, instaed of LDAP://CN-Users,

第二件事是 DC =+ Environment.UserDomainName 这可能错了，因为通常游戏是这样的： LDAP：// OU =金融，DC = Fabrikam目录，DC = COM （有多个DC）

Second thing is DC=" + Environment.UserDomainName which maybe wrong, because ususally it is something like this: LDAP://OU=Finance,dc=fabrikam,dc=com (there is more than one DC)

您可以使用PowerShell的找到所有的DC。运行以下命令：

You can find all DC using powershell. Run following command:

New-Object DirectoryServices.DirectoryEntry
