如何实现ASP.NET标识:数据库"master"中的CREATE DATABASE权限被拒绝

Flo*_*Flo 11 vb.net sql-server asp.net asp.net-identity

首先,我已经在这里查了一下: ASP.Net Identity如何设置目标DB？

我现在收到这个错误

数据库"master"中的CREATE DATABASE权限被拒绝.

在这行代码上:

Dim user As User = manager.Find(Trim(Username.Text), Trim(Password.Text))

UPDATE

根据评论,我也在这里查看.

我真的不明白为什么这是一个角色问题,因为我正在重用一个已经正常工作的连接字符串来更新其他(非身份相关的)表.此外,我不明白为什么错误引用master表,因为我希望我不会尝试通过该manager.Find方法以任何方式连接到该表.

无论如何,我正在测试的用户已被分配到该sysadmin角色:

更新2

好的,感谢Jeremy在下面的评论我更近了一步......我需要将用户添加IIS APPPOOL\.NET v4.5到角色sysadmin,因为这是用户连接,如SQL Server分析器中所示(尽管我不确定添加此用户时的安全风险这个角色).无论如何,Find方法不再抛出错误并使用SQL Server探查器我看到执行此代码时触发了SQL语句Dim user As User = manager.FindByName(Trim(Username.Text))

奇怪的是:当我直接在SQL Server Management Studio中执行它时,我得到了一条返回的记录,但在我的代码中变量user是Nothing....它可以是什么？

您的连接字符串包含“User Id=sa;Password=XXXX”，因此该连接正在尝试使用 SQL Server 身份验证。您的 SSMS 登录属性的标题栏似乎正在标识 Windows 帐户，这意味着应该使用 Windows 身份验证。但该连接正在尝试使用 SQL Server 身份验证（而不是 Windows 身份验证）。如果尚未配置，可以将 SQL Server 的身份验证模式更改为支持 SQL 身份验证和 Windows 身份验证（“混合模式”身份验证），请参阅https://msdn.microsoft.com/en-us/library/ms188670.aspx。

或者，可以将连接字符串更改为使用 Windows 身份验证/集成安全性，参见https://msdn.microsoft.com/en-us/library/jj653752(v=vs.110).aspx#integratedsecurity
