SQL Server Service Broker -- 通过 VPN 在非域服务器之间进行通信

Question

如果两个 SQL Server 2008 实例都不在域中，是否有任何好的选择可以通过 Service Broker 连接，但我们可以完全控制登录名和凭据？

我们正在考虑将这项技术用于企业级数据整合，但我们的服务器在客户端站点上运行，并且未配置为任何域的成员。我们正在寻找让 Service Broker 在这种环境中进行通信的最轻松的选择。

您使用证书，这是专门为像您这样的场景设计的 Service Broker 身份验证选项。见How does Certificate based Authentication work。当端点配置了基于证书的身份验证时，握手将包含基于 SSPI Schannel 的身份验证交换（通常称为 SSL 或 TLS）。对等方使用的生成证书用于根据从证书部署派生的信任来授权连接。这意味着所使用的证书未针对特定属性进行验证，例如在“https://example.com”的情况下，“example.com”必须在证书上使用特定的 OID 和受信任的权威签名，但如果证书是已部署（即在主数据库中找到），则已部署证书的所有者就是身份。这允许您以安全的方式使用自签名证书和部署中的信任根（即系统管理员），而不是权威（即威瑞信）。这可能比您需要的信息更多:)

它的要点是这样的：

-------------------------------------
-- connect to server
-------------------------------------
use master;
go
create master key encryption by password = '...';
create certificate [<servername>]
  with subject = '<servername>'
  , start_date = '20100216'
  , expiry_date = '20150216';

create endpoint broker 
state = started
as tcp (listener_port = 4022)
for service_broker (authentication = certificate [<servername>]);

-- Export the public key to disk
backup certificate [<servername>]
to file = '\\someshare\<servername>.cer';

--------------------------------
-- connect to client
--------------------------------
use master;
go
create master key encryption by password = '...';
create certificate [<clientname>]
  with subject = '<clientname>'
  , start_date = '20100216'
  , expiry_date = '20150216';

create endpoint broker 
state = started
as tcp (listener_port = 4022)
for service_broker (authentication = certificate [<clientname>]);

-- Export the public key to disk
backup certificate [<clientname>]
to file = '\\someshare\<clientname>.cer';

--create an identity for server and import the server's certificate:
create login [<servername>] with password = '...';
alter login [<servername>] disable;
create user [<servername>];

create certificate [<servername>]
  authorization [<servername>]
  from file = '\\someshare\<servername>.cer';

--authorize <servername> to connect on the broker endpoint 
grant connect on endpoint::broker to [<servername>];

---------------------------------------
-- connect to the server
---------------------------------------

--create an identity for client and import the client's certificate:
create login [<clientname>] with password = '...';
alter login [<clientname>] disable;
create user [<clientname>];

create certificate [<clientname>]
  authorization [<clientname>]
  from file = '\\someshare\<clientname>.cer';

--authorize <clientname> to connect on the broker endpoint 
grant connect on endpoint::broker to [<clientname>];
