I am trying to connect to a SQL server using Windows authentication. I am doing it through node js on Visual Studio.
The SQL server is on my machine itself.
It had worked fine for the connection string
var config = {
server: '10.2.9.208',
database: 'DFMProAnalyticsCopy',
user: 'sa',
password: 'admin123#',
port: 1433 //default port number
};
But this was only for SQL authentication.
Now for Windows aunthentication, I have this connection string
var config =
"Driver ={SQL Server};Server = 10.2.9.208;Database=DFMProAnalyticsCopy;Trusted_Connection=True;";
This gives me error
Unknown driver SQL Server!
and this connection string
var config =
"Server = 10.2.9.208;Database=DFMProAnalyticsCopy;Trusted_Connection=True;";
gives error
Login failed for user ''
It is trying to attempt SQL authentication when I want Windows authentication. I have Mixed mode authentication ON.
I read at many places but am still unclear about it.
"Login failed for user ''" when trying to use Windows Authentication
Please help me.
EDIT 1:
I cannot use the configuration string as in SQL Server connection with jQuery and node js
because mine is centralised and anyone could be using it, so I need to use Trusted_connection=true or Integrated security = SSPI. I dont have windows login credentials of people using the system.
This worked for me. I had to provide an UID and password in the connection string, else it considered a null string for UID
var config = "Server={IPV4 of server};Database=dbname;Uid=domain\\username;Pwd=pwd";

I'm trying to connect to my MS-SQL DB with Google Apps Script using the JDBC function.
We use windows integrated security, but when i try to connect with this parameter i get an error saying that it's not supported.
I've already tried to provide my windows credentials and using the param "IntegratedSecurity=true" but can't connect, tried with server IP and Name but doesn't work either.
var address = 'serverIP'; //ex. '10.1.1.1:1433'
var user = ';username=username';
var userPwd = ';password=password';
var db = 'dbname';
var dbUrl = 'jdbc:sqlserver://' + address + ';databaseName=' + db;
function readData() {
var conn = Jdbc.getConnection(dbUrl,user,userPwd);
}
I've tried this form too:
var conn = Jdbc.getConnection("jdbc:sqlserver://MyServerIP:1433;databaseName=DBName;integratedSecurity=true");
It should connect to the server but all I get is errors
The errors are
In the first form:
"Unable to connect to a database. Check the connection string,
username and password. (line 12, file "Code")"
And in the second form:
"The following connection properties are not
supported: integratedSecurity. (line 13, file "Code")"
The instructions for using Windows Integrated Authentication from non-Windows platforms is here: Using Kerberos integrated authentication to connect to SQL Server On Windows you have an additional option using a platform .dll as described here: Connecting with integrated authentication On Windows
I have no idea whether either of these is viable in whatever "Google Apps Script" is.
I m operating on Windows Server 2008 and I want to connect my application to a local SQL Server database .
I have read this: https://codedark.xyz/blog/connecting-to-ms-sql-server-with-knex
I have enabled TCP/IP connections to the server as well as default port 1433 for SQL Server. I then restarted the server instance.
I'm trying to connect with Windows authentication and my connection string looks like this :
mssql: {
client : "mssql",
connection: {
server : "localhost",
user : "windowsusername",
password : "windowspassword",
options: {
port: 1433,
database : "mydb",
encrypt: true
}
},
}
I get this error :
Login failed for user 'windowsuser'
My question: is it possible to connect to a local SQL Server database using Windows authentication? And if yes, which are the right credentials?
If you wish to use windows authentication, which I would recommend, then remove the user and password information and try this:
Integrated Security: "SSPI"
Depending on your set up, using windows auth could prove difficult unless you can specify the connection string as an actual string and not an object.
See this question for additional information Stack Reference
i must connect to a sql server with windows authentication
sql server is on machine 192.168.3.6
web server (client) is on my machine 192.168.3.10
I'm using JTDS driver
dbUrl=jdbc:jtds:sqlserver://192.168.3.6:1099/db_test;instance=test
Connection con = DriverManager.getConnection( dbUrl, "", "" );
I have username and password of administrator user of sql server !
I also put ntlmauth.dll into c:\windows and c:\windows\system32 and I have always error:
java.sql.SQLException: Login failed for user '(null)'. Reason: Not
associated with a trusted SQL Server connection.
Any idea to solve my problem ?
Thank you very much
See jTDS FAQ http://jtds.sourceforge.net/faq.html
you will have to pass useNTLMv2=true and domain=yourdomain
What you can do is something like:
String url = "jdbc:jtds:sqlserver://MYPC/MYDB;instance=SQLEXPRESS";
Class.forName("net.sourceforge.jtds.jdbc.Driver");
Connection conn = DriverManager.getConnection(url);
Make sure you have jtds.jar in the Java build path.
Also, add "-Djava.library.path="PATH\JTDS\x64\SSO" where 'Path' is where your SSO folder is after installing the JTDS driver (this is where you have your ntlmauth.dll).
Here is a short step-by-step guide showing how to connect to SQL Server using jTDS (as well as JDBC) with Windows authentication should you need more details. Hope it helps!
It installed automatically with Visual Studio 2010 Ultimate. I didn't create any users for the server or ANYTHING.
I'm using:
string connectionString = #"Server=.\SQLEXPRESS;Database=SportsStore;Trusted_Connection=yes;";
I get error that authentication failed. So the server is being found, but my credentials are wrong. What would the default login and password be?
Edit: Still not working! :(
Here's my connection string:
string connectionString = #"Server=.\SQLEXPRESS;Database=SportsStore;Integrated Security=SSPI;";
And the error message:
Cannot open database "SportsStore"
requested by the login. The login
failed. Login failed for user
'ToshibaLaptop\Sergio'.
If you are using SQL Server authentication you could try the username sa and blank password but I am not sure whether this is by default. Integrated Windows authentication should work, so you should be able to connect with your Windows account:
string conn = "Data Source=.\SQLExpress;Initial Catalog=mydb;Integrated Security=SSPI;";
You probably should not connect using Sql Server Authentication.
Log in as an Administrator on the box, connect using Integrated Windows Authentication, and you should be a system admin.
The error message indicates that SQL Server can't open the database. I think you're successfully authenticating, but having a problem connecting to the database. Is the database available?
You can do a test by changing the database to master in your connection string. If that succeeds, then you're problem is related to the database. I understand that you may get other errors, but the test is to confirm that you can login to SQL Server.
For me SQL Server (SQLEXPRESS) service was disabled so it was throwing the error. After enabling the service SSMS is working fine
Goto Run command and type services.msc and click on OK button
Services window will open. Check the status of SQL Server (SQLEXPRESS) service
If the service is not running, then start the service
Now try logging in again in the SSMS.
In SQL 2008 if you use the defaults there won't be a SQL Server user only Windows Authentication will be enabled - and it will only work for the user that installed the application would have access via their Active Directory authentication.
I've been at this for a few days now and the error stays the same.
Login failed for user". ClientConnectionId
I have connected to the database successfully, but the "login failed for user" which doesn't make sense because the username is "sa" and the password "tazmo1", the same as the login and password was when installed SQL Server Express. This is what i have so far...
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String userName = "sa";
String password = "tazmo1";
String url = "jdbc:sqlserver://localhost:1433;databaseName=AdventureWorks2012;integratedSecurity=true";
con = DriverManager.getConnection(url,userName,password);
I have also used
con = DriverManager.getConnection(url)
and
DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=AdventureWorks2012;integratedSecurity=true")
even used
DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=AdventureWorks2012,user="sa",password="tazmo1");`
I've been reading numerous stackoverflow forums that point me to the same thing, make sure the TCP/IP dynamic ports are removed add 1433 to all the TCP/IP Port. I have done all that, and it connect then stops working as the "login failed". Please help me fix this issue.
You have IntegratedSecurity set to true. That will use your Windows Auth credentials, even if you are passing in the SQL Auth credentials.
The problem is: you are using integratedSecurity=True which means you are using microsoft's standard instead of yours, set it to false and it will use YOUR username and password. You could also try this, instead of integratedsecurity: "databaseName=AdventureWorks;user=MyUserName;password=*****;";
