在this article’s概述中,它提到了这个(强调我的)：

When you use Windows authentication to connect to sql Server,you use
either Kerberos or NTLM authentication depending on the configuration
of your servers and domain. You might not be able to use Kerberos
authentication if:

• Your database client and database server are separated by a firewall
  which prevents Kerberos authentication.

• Your application server and database server are in separate domains
  with no trust.

In these situations,you can use either mirrored local accounts or sql
authentication. With mirrored local accounts,you configure two
accounts on each server with identical user names and passwords. You
must ensure that the passwords remain the same.

我假设这只是意味着在两台机器上创建一个具有相同用户名和密码的Windows用户,但是我怀疑这会起作用.当我在数据库客户端上为此用户添加权限时,它会在用户名前加上servername,并且在数据库服务器上创建数据库登录时会发生同样的事情.

这是创建镜像本地帐户的意义吗？如果是这样,考虑到用户在不同的域中,这是如何工作的？
