成功連接測試后，“用戶登錄失敗”

Question

我正在使用Visual Studio 2013構建第一個C＃應用程序的生產版本，這兩個版本都托管在Amazon上。 在初始運行期間創建第一個用戶時，即使登錄憑據可以成功連接，也會拋出[SqlException (0x80131904): Login failed for user 'databaseuser'.] 。 誰能看到原因？ 在此先多謝，因為我很生氣。 詳細信息和我嘗試過的是：

測試數據庫位於SQL Express上，其架構已導入到SQL Server Standard Edition的實例中。 已成功運行的測試Visual Studio文件夾已使用Windows資源管理器復制到另一個位置，並已重命名用於生產。 生產Web.config連接字符串已更改為生產SQL實例以及相應的用戶名和密碼； 登錄名在Server Explorer的“測試連接”， .edmx模型瀏覽器“添加/更新”存儲過程中成功測試，並使用“ databaseuser”憑據直接登錄到SQL Server。 SQL實例設置為SQL Server和Windows身份驗證模式。 “數據庫用戶”對SQL實例中的兩個數據庫都具有讀/寫權限。

代碼在public class AccountMembershipService : IMembershipService失敗public class AccountMembershipService : IMembershipService

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連接字符串

<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;"

     <add name="UsersDbEntities" connectionString="metadata=res://*/

Answer 1

我不確定為什么這行得通，但是這顯然可以解決問題：我僅通過讀/寫訪問權限刪除了“ databaseuser”的Web.config憑據，並將其替換為數據庫管理員憑據。 該應用程序已成功測試。 然后將管理員憑據替換為原始的“ databaseuser”憑據，一切正常。 似乎由於某種原因，該應用程序需要管理員首次訪問該連接，然后，讀/寫用戶可以從此開始執行相同的操作。

感謝Nick.McDermaid的回答。 它們都是正確的，並且已經完成，但是由於某種原因，程序需要管理員先向其顯示方式。
