I want to add a user in SQL Server 2008 so I can use SQL Server Authentication instead Windows Authentication for connecting to SQL, and have tried this code to create a user with login: 

CREATE login [newLog] with password = 'passnewLognewLog'

I get it done, but when I want to connect to SQL Server using SQL Authentication, I get this message

Cannot connect to "Mydb"
additional information: Login failed for user 'newLog'. (Microsoft SQL Server, Error: 18456 )

What am I missing here?

After creating the login, you need to add the user to the database. This example is from the sql server documentation for CREATE USER:

CREATE LOGIN AbolrousHazem 
    WITH PASSWORD = '340$Uuxwp7Mcxo7Khy';
USE AdventureWorks2008R2;
CREATE USER AbolrousHazem FOR LOGIN AbolrousHazem;
GO

Edit

To test, I ran this T-SQL:

create login Foo with password ='f00';
go

use TestDB
create user Foo for Login Foo
go

and opened a connection successfully using this connection string:

"Server=<server>; user id=Foo; password=f00; initial catalog=TestDB"

  • I have tried that but can not login using SQL Server Authentication – edgarmtze Jul 10 '11 at 21:23
  • what else do I have to do so I can connect using SQL Server Authentication with the created user?? – edgarmtze Jul 10 '11 at 21:30
  • @cMinor, see my edit. I was able to create a login, add the user and connect successfully. Is it possible you executed the `create user` statement in the context of a different database (perhaps master)? – Jeff Ogata Jul 10 '11 at 21:39

  1. You need to create a user for the login, e.g.

    CREATE USER [newLog] FOR LOGIN [newLog] WITH DEFAULT_SCHEMA=[dbo]

  2. Check that mixed authentication is enabled: https://stackoverflow.com/a/1719476/188926

Try the following. They worked for me when I had this connection issue.

 -When you are adding SQL user, make sure 'enforce password policy' is unchecked.
 -Make sure that user is mapped to the database with proper permissions.
 -on SSMS, right click server and then go to Security tab. Select 'SQL Server and Windows Authentication mode' option.
 -restart PC.
