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=*****;";

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 have a web site and I'm trying to setup a DSN instead of using a connection string because it seems more secure.
The following connection string works fine in my site:
"Server=servername; database=mydb; user id= web.account; password=PassW0rd!; Integrated Security=SSPI"
However, when I try to set up a DSN (using the 64-bit odbc admin) I get the following error:
Connection failed:
SQLState: '28000'
SQL Server Error: 18456
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'web.account'
Keep in mind, I'm using the same account and password I use in the connection string (which works). It's weird too because the error occurs right after I click 'Next' on the "How should SQL Server verify the authenticity of the login ID?" page.
It seems like the odbc admin does not even try to connect to the server to verify the credentials. What can I check to prove this / How can I fix this?
Things I've tried:
I have checked the server authentication mode, as proposed in other solutions, and that is set to "SQL Server and Windows Authentication mode", as it should be.
I have tried creating both a User and System DSN - both get the same error, this seems like further evidence that it's not trying to connect to the server to check the credentials.
I have tried the same DSN creation on multiple servers, all have the same problem. Is it possible the SQL Server is refusing these types of connections?
UPDATE 1:
The DBA just told me that the web.account is actually a Windows account, not an SQL account. I guess that's why the odbc isn't working, because it doesn't try to connect as a different windows user, only as the current windows user. So now the question is, how do I set up a DSN with a different windows account? Or, is that even possible?
This post has a response that says DSNs setup with NT authentication are specifically for the entire system, not a specific account, so a runas command could be used from cmd, like so:
runas /netonly /user:domain\web.account "C:\Windows\SysWOW64\odbcad.exe"
It will then ask you for the web.account password. Then you can create a DSN, and this should work.
UPDATE: I had to add the web.account user to my Administration Group using this fine how-to. Then I had to run cmd as my elevated account. Then ran the runas command I showed above. Then, I was finally able to create a non-native DSN, which allowed me to connect to the Data Server as a different Windows user.
Still waiting for DBA to check the logs to say this actually worked or not, but I feel pretty good about it. Will update after confirmation.
Try the following:
Data Source=servername;Initial Catalog=mydn;Persist Security Info=True;User ID=web.account;Password=Passw0rd
This is what I use to connect.
I've written a very simple JDBC login test program. And after all kinds of problems I've almost got it working. Almost, just can't seem to get past this problem:
SQLServerException: Login failed for user xxxxx
I created a simple database PersonInfo then I created user user1 password1 (SQL authentication). And after trying everything was unable to connect to the database.
I am using SqlServer2008 on Win 7, I've got the latest JDBC driver from Microsoft.
My code is:
import java.sql.*;
public class hell {
public static void main(String[] args) {
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
Connection conn= DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=PersonInfo;user=Sohaib;password=0000;");
System.out.println("connected");
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
Here's the Exception
Exception: Unable to get connect
com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'Sohaib'.
and all other supporting errors.
Is your SQL Server in 'mixed mode authentication' ? This is necessary to login with a SQL server account instead of a Windows login.
You can verify this by checking the properties of the server and then SECURITY, it should be in 'SQL Server and Windows Authentication Mode'
This problem occurs if the user tries to log in with credentials that cannot be validated. This problem can occur in the following scenarios:
Scenario 1: The login may be a SQL Server login but the server only accepts Windows Authentication.
Scenario 2: You are trying to connect by using SQL Server Authentication but the login used does not exist on SQL Server.
Scenario 3: The login may use Windows Authentication but the login is an unrecognized Windows principal. An unrecognized Windows principal means that Windows can't verify the login. This might be because the Windows login is from an untrusted domain.
It's also possible the user put in incorrect information.

In my case, I had to activate the option "SQL Server and Windows Authentication mode", follow all steps below:
1 - Right-click on your server
2 - Go to option Security
3 - Check the option "SQL Server and Windows Authentication mode"
4 - Click on the Ok button
5 - Restart your SQL Express Service ("Windows Key" on the keyboard and write "Services", and then Enter key)
After that, I could log in with user and password
I ran into the same issue, and I fixed it by adding my windows username to SQL and then to my server, here is how I did:
First, create a new login with your Windows username:
Click Search, then type your name in the box and click check names.
Then add your that user to the server:
Right click on the Server > Permissions > Search > Browse > Select your user
(You will notice that now the user you created is available in the list)
I hope it helps ;-)
We got this error when reusing the ConnectionString from EntityFramework connection. We have Username and Password in the connection string but didn't specify
"Persist Security Info=True".
Thus, the credentials were removed from the connection string after establishing the connection (so we reused an incomplete connection string). Of course, we always have to think twice when using this setting, but in this particular case, it was ok.
I got the same error message when trying to connect to my SQL DB in Azure (using sql-cli). The simple solution was to escape the password with single quotes like this:
mssql -s server.database.windows.net -u user#server -p 'your_password' -d your_db -e
Also make sure that account is not locked out in user properties "Status" tab
For Can not connect to the SQL Server. The original error is: Login failed for user 'username'. error, port requirements on MSSQL server side need to be fulfilled.
There are other ports beyond default port 1433 needed to be configured on Windows Firewall.

We solved our Linux/php hook to SQL Server problem by creating a new login account with SQL Server authentication instead of Windows authentication.
Just in case any one else is using creating test users with their automation....
We had this same error and it was because we had recreated the user (as part of the test process). This caused the underlying SID to change which meant that SQL couldn't properly authenticate the user.
We fixed it by adding a drop login command to our testing scripts to ensure that a previously created user (with the same user name) was no longer present on the instance.
I faced with same problem. I've used Entity Framework and thought that DB will be created automatically. Please make sure your DB exists and has a correct name.
In my case I have configured as below in my springboot application.properties file then I am able to connect to the sqlserver database using service account:
url=jdbc:sqlserver://SERVER_NAME:PORT_NUMBER;databaseName=DATABASE_NAME;sendStringParametersAsUnicode=false;multiSubnetFailover=true;integratedSecurity=true
jdbcUrl=${url}
username=YourDomain\\$SERVICE-ACCOUNT-USER-NAME
password=
hikari.connection-timeout=60000
hikari.maximum-pool-size=5
driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
try using this connection string
Server=ServerName;Database=DbName;Trusted_Connection=SSPI;MultipleActiveResultSets=true;TrustServerCertificate=true
If you are using Windows Authentication, make sure to log-in to Windows at least once with that user.
Previously I was using the Windows Authentication without problems, then occurred me the error below.
"Failed to generate SSPI context."
Witch I resolve by changing my connection string from
Server=127.0.0.1;Database=[DB_NAME];Trusted_Connection=True;
to
Server=127.0.0.1;Database=[DB_NAME];Trusted_Connection=False;
Then the next error occurred me
"Login failed for user ''."
To solve this problem I used the sa user. Access the sa user to update de password if you need (on the SQL server Security > Logins > sa (right click) > Properties > General)) and then update the connection string to..
Server=127.0.0.1;Database=[DB_NAME];User Id=sa;Password=[YOUR_PASSWORD]
You can use another user of your choice.
I am a beginner in Excel VBA and faced a problem: I can connect to remote SQL Server through Management Studio, but got error when connecting through Excel VBA.
Below is my connection string and the error code.
Const connection_string As String = "Provider=SQLOLEDB.1;Persist Security Info=True;Integrated Security=SSPI;Initial Catalog=RPGTFDB;Data Source=122.xxx.xxx.xxx;User ID=sa;Password=xxx"
Error is:
Run-time error (80004005): Login failed for user ". The user is not associated with a trusted SQL Server connection.
Is it not able to get the User ID?
However when I connect to local computer, like 127.0.0.1, the above connection string works.
Thanks a lot!
In your connection string you should not use
User ID=sa;Password=xxx
As the error seems to be indicating that only Windows Logins are enabled on the SQL Server and this connection string item is only for SQL Logins.
Do you have to punch in a login and password when connecting with management studio? If not then I suggest you have a database that authenticates a connection using your windows login.
If this is the case, then remove the User ID and Password bits and insert Trusted_Connection=Yes instead.
Finally, the connection string is created using UDL application.
Despite I still cannot find any difference between the string and the manual created one, it works!
Follow the instructions in this link:
http://social.technet.microsoft.com/wiki/contents/articles/1409.how-to-create-a-sql-connection-string-for-an-application-udl-file.aspx
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.
