在C＃中連接到ActiveDirectory失敗

Question

我嘗試在C＃中連接到AD

如果我連接到根，它將成功而不會引發錯誤。

        try {
            DirectoryEntry de = new DirectoryEntry("LDAP://COMPANYDOMAIN.COM", "username", "password");
            object nativeObject = de.NativeObject;
        } catch(DirectoryServicesCOMException) { }

如果我使用如下所示的另一種方式連接，它將引發the specified domain either does not exist or could not be contacted.

        try {
            DirectoryEntry de = new DirectoryEntry("LDAP://DC=COMPANYDOMAIN,DC=COM", "username", "password");
            object nativeObject = de.NativeObject;
        } catch(DirectoryServicesCOMException) { }

如果我連接到子OU，它將引發the specified domain either does not exist or could not be contacted. 太

        try {
            DirectoryEntry de = new DirectoryEntry("LDAP://OU=KEE2, DC=COMPANYDOMAIN,DC=COM", "username", "password");
            object nativeObject = de.NativeObject;
        } catch(DirectoryServicesCOMException) { }

我可以使用LDAPADMIN GUI工具進行連接並查看AD中的結構：

ROOT
  OU=KEE2
  OU=KEE
  OU=other..

我在這里做錯了什么？

Answer 1

事實證明，所使用的語法是錯誤的……必須像這樣……然后沒有錯誤。

LDAP://companydomain.com/ou=kee2,dc=COMPANYDOMAIN,dc=com
