I am logged with windows authentication and create an entry/user in the login table.
The new testuser has a sql-server authentication, but if a try to login local or remote, only fault 18456.
Is there any trick... this should be so simple as explained... but should work?
i believe it's just that the SQL server authentication is disabled by default installation. go check your SQL server properties in management studio (right-click on the server in object explorer, then select 'properties'), select 'security' menu in the left panel. you have the 'server authentication' option on the top of the right-side options panel with 2 options. make sure that the 'SQL server and windows authentication mode' is selected, not the 'windows authentication mode' which is default.
I don't quite understand your question - can you clarify a bit?
You're logged in with a Windows account - so does that Windows account (or a Windows group it belongs to) have a "login" in SQL Server?
How do you try to login with the new "testuser" ? How are you trying to connect? From an ADO.NET application? SQL Server Management studio?? Error 18456 can mean "login failed" - does your "testuser" have a SQL login? And is that login allowed to use the database you're trying to use??
Please give us a bit more information to go on - thanks!

I am trying to create a login in SQL Server Management Studio. I was successful in the creation, but after that I can't login in it. I will leave the steps below
Fixed the problem. Solution
Check your server Properties --> Security --> Server authentication
If SQL Server and Windows Authentication mode selected you will be fine.
If not, Follow steps below:
Right-click on your server
Go to option Security
Check the option "SQL Server and Windows Authentication mode"
Click on Ok button
Restart SQL Express Service ("Windows Key" on keyboard and write "Services", and then Enter key)
After SQL services restarted, you should be able to login with user and password
These are the steps to take to create a login:
Click right on database ,choose security , choose SQL with Windows authentication and Both failed....
Restart SQL Server service
Create database
Create login and a sign the name of database to the user from choosing "Default Database"
Be sure you a sign to user mapping database
Server name :
if local choose the name of computer name that you choose from first if you do not know choose from drop list of server name to see what available name
if you have a ip static put the server name like that :000.00.00.00\\SQLSERVER2019,1433, name and password.
So I've been tasked to install DNN onto my system. I am using the Microsoft Web Platform Installer. I am being asked for the password for the 'sa' account. I do not know the password for the account. So when I tried to use the Microsoft SQL Server Management software to change the password I get the following message:
"Change password failed for Login 'sa' (Microsoft.SqlServer.Smo)
Additional Information:
An exception occurred while executing a Transact-SQL or batch. (Microsoft.SqlServer.ConnectionInfo)
Cannot alter the login 'sa', because it does not exist or you do not have permission. (Microsoft SQL Server, Error: 15151)"
How would I obtain permission to change the password? Or am I missing the point entirely and should be doing something else to install the software??
I would assume the issue lies with SQL, what steps should I take to rectify this problem??
SQL Server uses either/both of "Windows authentication" and "SQL Server authentication".
By default, MSSQL installs with ONLY "Windows authentication". "sa" requires MSSQL authentication.
SOLUTION:
http://technet.microsoft.com/en-us/library/ms188670.aspx
1) Go into SQL Server Management Studio Object Explorer, right-click the server, and then click Properties.
2) On the Security page, under Server authentication, select the new server authentication mode, and then click OK.
3) In the SQL Server Management Studio dialog box, click OK to acknowledge the requirement to restart SQL Server.
4) In Object Explorer, right-click your server, and then click Restart.
Are you able to login via Windows Authentication and change it that way? If so, that would be the best way to do it.
If the only account that has admin access is the sa account though, then you can try starting SQL server in single user mode and then resetting the sa password. Note that this method requires local admin access to the server itself.
http://sigkillit.com/2013/01/02/recover-sa-password-on-microsoft-sql-server/
Sounds to me like you could login with the SA account into SQL server, it will likely prompt you to change your password (first time logging in) and then you would be good to go after that.
That being said, I never recommend setting up DNN to connect to SQL server with the SA account. Each DNN database should have its own DB user, that way if one DNN install gets compromised for some reason, they can't reach out into other databases on the same server.
EDIT: a little more info

In SQL Server you should go through and create a new database. I always create a database with the same name as the website, so in this case DNNDEV.ME. Once you have created the database, create a user that can access that database. I always use SQL authentication, turn off the enforce password requirements, and give the user DB Owner and Public access to the DNNDEV.ME database. Remember the username and password you create here as you will need them when you walk through the Installation screen for DotNetNuke.
My problem is I cannot login into SQL Server after I've created a user. The user creation is successful, since the new user is listed under security/logins.
How to solve this issue ???
Login failed for user 'sims'. The user is not associated with a
trusted SQL Server connection. (Microsoft SQL Server, Error: 18452)
SQL Server was not configured to allow mixed authentication. Here are steps to fix:
Right-click on SQL Server instance at root of Object Explorer,
click on Properties.
Select Security from the left pane.
Select the SQL Server and Windows Authentication mode radio button, and
click OK.
Open up Services and restart the SQL Service (SQLEXPRESS) Windows service.
Try setting your authentication mode to mixed mode. Your server does probably not accept logins using sql server accounts.
Open properties
Go to "Security"
Select "SQL Server and Windows Authentication mode"
Right click Server for properties...
properties
I have this problem.
I first connect(log) to SQL Server using SQL Management Studio the authentication is set to Windows Authentication.
Then I go to the Security => Logins folder and add a user, the authentication is: SQL Server authentication, I give him also the sysadmin role [all roles]
I try to login as that user, but I can't
I tried everything but no result
How can this be corrected?
You should enable SQL Authentication; it isn't enabled by default.
In SSMS, right-click on the top-level (server) node, select Properties. Then click on Security in the left-hand panel, then select the "SQL Server and Windows Authentication mode" radio button in the right-hand panel.
You also have to restart you sql server. For me it start working only after restart.
I'm using using Windows Vista and I'm having trouble logging in with a newly created user.
I open SQL Server Management Studio.
I create a new Login by right-clicking on Security->Logins.
Check: SQL Server Authentication
Login name: tester
Password: test
Click OK
I added this user to User Mapping to my database of choice.
Click File -> Connect Object Explorer, select SQL Server Authentication and enter tester/test and click Connect.
I get an error:
Login failed for user 'tester'. (Microsoft SQL Server, Error: 18456"
with Severity = 14 and State = 1.
What causes this error and how do I login with my user?
SQL Server was not configured to allow mixed authentication.
Here are steps to fix:
Right-click on SQL Server instance at root of Object Explorer, click on Properties
Select Security from the left pane.
Select the SQL Server and Windows Authentication mode radio button, and click OK.
Right-click on the SQL Server instance, select Restart (alternatively, open up Services and restart the SQL Server service).
This is also incredibly helpful for IBM Connections users, my wizards were not able to connect until I fxed this setting.
If you haven't restarted your SQL database Server after you make login changes, then make sure you do that. Start->Programs->Microsoft SQL Server -> Configuration tools -> SQL Server configuration manager -> Restart Server.
It looks like you only added the user to the server. You need to add them to the database too. Either open the database/Security/User/Add New User or open the server/Security/Logins/Properties/User Mapping.
You'll likely need to check the SQL Server error logs to determine the actual state (it's not reported to the client for security reasons.) See here for details.
Login to Server as Admin
Go To Security > Logins > New Login
Step 1:
Login Name : SomeName
Step 2:
Select SQL Server / Windows Authentication.
More Info on,
what is the differences between sql server authentication and windows authentication..?
Choose Default DB and Language of your choice
Click OK
Try to connect with the New User Credentials, It will prompt you to change the password. Change and login
OR
Try with query :
USE [master] -- Default DB
GO
CREATE LOGIN [Username] WITH PASSWORD=N'123456', DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english], CHECK_EXPIRATION=ON, CHECK_POLICY=ON
GO
--123456 is the Password And Username is Login User
ALTER LOGIN [Username] enable -- Enable or to Disable User
GO
