Answer 1

发布数据库后，您只能使用sql身份验证访问数据库。

Answer 2

In IIS7 the application pool by default runs under the IIS AppPool\\[Application Pool Name]

That means, if your app pool is called "MyWebSite", then you must give the following user permissions to use your database: IIS AppPool\\MyWebSite

It won't be in any list, so you'll have to type it as above when adding it.

I suggest making it database owner if you're in doubt about which permissions to give it. If it works, you can always refine the permissions later
