＆＃39;用户登录失败＆＃39;成功的测试连接

Question

我使用Visual Studio 2013构建我的第一个C＃应用程序的生产版本，这两个版本都在亚马逊上托管。在初始运行期间创建第一个用户时，即使登录凭据可以成功连接，也会引发[SqlException (0x80131904): Login failed for user 'databaseuser'.]。谁能明白为什么？非常感谢，因为我很恼火。细节和我尝试过的是：

测试数据库在SQL Express上，其架构已导入SQL Server Standard Edition实例;成功运行的测试Visual Studio文件夹已使用Windows资源管理器复制到另一个位置并重命名用于生产;生产的Web.config连接字符串已更改为生产SQL实例以及相应的用户名和密码;登录在服务器资源管理器＆＃34;测试连接＆＃34;，.edmx模型浏览器添加/更新存储过程中成功测试，并使用＆＃34; databaseuser＆＃直接登录到SQL Server 34;证书。 SQL实例设置为SQL Server和Windows身份验证模式。 ＆＃34;数据库用户＆＃34;对SQL实例中的两个数据库都具有读/写权限。

代码在public class AccountMembershipService : IMembershipService

中失败

private MembershipProvider _provider;
public MembershipCreateStatus CreateUser(string userName, string password, string email)
{
    MembershipCreateStatus status;
    _provider.CreateUser(userName, password, email, null, null, true, null, out status);
    //FAIL ON THE ABOVE LINE!        
    return status;
}

Web.config连接字符串

<connectionStrings>
     <add name="DefaultConnection" providerName="System.Data.SqlClient" 
          connectionString="Server=[production endpoint];
          Database=UsersDb;User ID=databaseuser;Password=[password];
          Trusted_Connection=False;Connection Timeout=30;" />
     <add name="WorkplaceEntities" connectionString="metadata=res://*/Data.Workplace.csdl|
          res://*/Data.Workplace.ssdl|res://*/Data.Workplace.msl;
          provider=System.Data.SqlClient;provider connection string=&quot;
          data source=[production endpoint];initial catalog=Workplace;user id=databaseuser;
          password=[password];MultipleActiveResultSets=True;App=EntityFramework&quot;" 
          providerName="System.Data.EntityClient" />
     <add name="UsersDbEntities" connectionString="metadata=res://*/
          Data.UsersDb.csdl|res://*/Data.UsersDb.ssdl|res://*/
          Data.UsersDb.msl;provider=System.Data.SqlClient;
          provider connection string=&quot;data source=[production endpoint];
          initial catalog=UsersDb;user id=databaseuser;password=[password];
          MultipleActiveResultSets=True;App=EntityFramework&quot;" 
          providerName="System.Data.EntityClient" />
</connectionStrings>

Answer 1

我不确定为什么会这样，但是这里显然已经解决了问题：我删除了＆＃34; databaseuser＆＃34;的Web.config凭据。只有读/写访问权限，并用数据库管理员凭据替换它们。应用程序测试成功。然后将管理员凭据替换为原始＆＃34;数据库用户＆＃34;凭证，一切正常。似乎由于某种原因，应用程序需要管理员第一次访问连接，然后读/写用户也可以这样做。

感谢Nick.McDermaid的答案。他们都是正确的并且正在完成，但由于某种原因，该程序需要管理员首先显示它。
