C# 如何进行LDAP用户校验？

示例代码如下：

private bool Authenticate(string userName, string password, string domain)

{

bool authentic = false;

try

{

DirectoryEntry entry = new DirectoryEntry(“LDAP://”+domain, userName, password);

object nativeObject = entry.NativeObject;

authentic = true;

}

catch (DirectoryServicesCOMException) { }

return authentic;

}
