PrincipalContext构造函数和AD查询

Question

有人可以稍微详细解释一下，为什么以下代码有效：

using (PrincipalContext pc = new PrincipalContext(ContextType.Domain,"some.domain.com", "username","password"))

但是当我尝试将任何其他内容传递给构造函数时，例如IP地址和端口，我会收到错误？

using (PrincipalContext pc = new PrincipalContext(ContextType.Domain,"123.45.56.78:910", "username","password"))

以上几行不起作用，但我希望能够从外面的计算机访问AD，如果它有有效的凭据，我该怎么做，以及为什么一个例子可以工作，而另一个没有？

Answer 1

You are close, you are are just missing LDAP:// at the beginning of your IP address.

using (PrincipalContext pc = new PrincipalContext(ContextType.Domain,"LDAP://123.45.56.78:910", "username","password"))

LDAP is a protocol that allows you to communicate with your Active Directory domain.
