我收到错误
SqlException (0x80131904): 用户 'raam030' 登录失败
对于我的 ASP.NET MVC4 应用程序。使用本地 SQL Server 在我的开发机器上工作正常，但是当我将它部署到网络托管时，这就是我得到的。我搜索了相同的问题，有很多但到目前为止没有一个对我有帮助。
我有下面的堆栈跟踪，我三重检查并确保我的连接字符串是正确的并且 SQL Server 身份验证是正确的。虽然我的托管服务连接字符串不需要密码信息，但我尝试了没有和使用硬编码密码和用户名的变体。
<connectionStrings>
<add name="RMSDelta"
connectionString="Data Source=mssql2.openhost.net.nz;Integrated Security=False;User ID=myusername; Password=mypassword;Connect Timeout=15;Encrypt=False;Network Library=dbmssocn;Packet Size=4096"
providerName="System.Data.SqlClient" />
</connectionStrings>
我正在使用代码优先方法。我的数据库名称与我用作连接字符串名称的名称相同，用于在我的上下文类中作为连接字符串传递的名称相同。确保提供者名称正确。除了数据访问部分（和需要数据的页面）之外，其他所有页面都可以在我的应用程序中正常工作。我不确定还能从这个堆栈跟踪中得到什么？
请帮我。
