Asp Net Core MVC: Login failed for user 'IIS APPPOOL \ Readdy'.

The following error bulletin comes when you desire to access an SQL Server in an Asp Net Cadre ii MVC application.

-> An error occurred using the connectedness to database

Status: solved

Fault, error message in the stdOut logfile

An error occurred using the connectedness to database 'readdy' on server '.\SQLEXPRESS'.

System.Data.SqlClient.SqlException (0x80131904): Cannot open database "readdy" requested by the login. The login failed.

Login failed for user 'IIS APPPOOL\Readdy'.

Trouble:

The IIS Internet user and the IIS AspNetCore application do not have access to the local SQL server as the SQLExpress server.

That makes sense, because otherwise whatsoever unauthorized person could access the database.

And so you have to give the current Internet user the rights to access the SQL Server.

Solution:

You create a new user,

Allocates this new user as Identiy in the ApplicationPool

And in addition, the database is assigned every bit a mapping for this user in the SQL Securtiy area.

Step 1: Create a Windows user

Under Computer Management-> System Tools-> Local Users and Groups

If you create a new user among the users and give this a fixed password, which does not go out

Step 2: Create application pool

Under the IIS Server -> Applications Pools yous create a new Application Puddle with Add Application Pools

This is what you tin do with Net CLR Version: unmanaged code, because this is not role of IIS in AspNetCore applications. is managed

Applicationpool -> Identity

And in the new application pool in Avant-garde Settings, information technology enters the identity on the new Windows user

Applicationpool -> Identity-> Enter Custom User

Under Custom User and then select the new Windows user and confirms information technology with the default password

Set application pool

Then you lot put in the AspNet Core application under Basic Settings

Then open Application Pool with Select and select the new application pool AspNetCore_Sql_User

Footstep three:

Create new SQL Server user

In SQL Server you create under SQL Server-> Security -> Logins

A new user.

With the new user, you then enter the newly created Windows user every bit Readdy-Server \ AspNetCore_SQL_User

Step 4: Database-> User Mapping

And then enters the user in the database under Mapping

To do this, select under SQL Server-> Security-> Logins the new SQL user login.

In the dialog: Login Backdrop, enter the table every bit active in User Mapping ->.

In the lower part you enter the roles Database role memberschip db_datareader, db_datawriter and others.

Restart the AspNetCore applications

If i so addresses the Asp Core2 application in the browser with the URL of the website, the new SQL information should appear from the database
