I want my normal (role public) user123 (SQL Auth, not PAD, not sysadmin) to login to SQL Server 2019 (Developer version).
I have SQL Server and Windows Authentication mode.
I have protocols in SQL Server Network Configuration enabled
(TCP/IP, Local Machine, Named Pipes).
App connecting to DB is written in Visual Studio cpp, with SQLDriverConnect() function.
And I still get this error:
Login failed for user 'user123'. Reason: Login-based server access validation failed with an infrastructure error. Login lacks connect endpoint permission. [CLIENT: 127.0.0.1]
Error: 18456, Severity: 14, State: 149.
When I give user123 sysadmin role, then he connects. But I don't want him to be sysadmin. In fact, I want two separate application to connect to the database with user123 credentials as standard public user. But actually even one application can't connect.
There's a list of permissions:
List of DB permissions
Any help and suggestions highly appreciated.
SOLUTION FOUND: Port in SQLDriverConnect() function shall be 1433 (default SQL instance) not 1434 (DAC Connection), with proper permission for public role on particular database (Connect, Select, Insert, etc.).
From the error message and the screenshot, I suspect that you might be connecting to the DAC rather than to the main SQL instance.
Please recheck your connection string in the application - or test using SSSMS
Im installing the MDM of Informatica.
MDM 10.2 - Jboss 6.4 EAP - SQL Server 11 - Windows Server 2008 R2.
During the creation of the schema 'sip_ant.bat create_bpm' i got this error
Microsoft ODBC Driver 13 for SQL Server : Login failed for user 'sa'.
(Same eeror with another user)
I already tried to use the Auth Mixed Mode and restarted the instance of the DB.
Error received is
D:\informatica\database\bin\common.xml:248: The following error occurred while executing this line:
D:\informatica\database\bin\mssql\database.xml:1214: Launched command return error code 1.
And that's the line of database.xml:1214 that refers:
collation_name="${activevos.collation}" param2=""${dbpath_short}"" param1="${activevos.password}">
Im able to login via SQLCMD on CMD with user 'sa' and other users.
MDM and SQL Server are on different Machine.
Any suggestion?
By default SQL Server will track failed logins and register it in the server log along with the reason. So check out your errorlog and look for errors 18456.
You can read the log by using SQL Server Management Studio by going to server, Management, SQL Server Logs, Current. Or any other way you prefer.
You'll find something like this:
2018-02-27 13:51:26.120 Logon Error: 18456, Severity: 14, State: 5.
2018-02-27 13:51:26.120 Logon Login failed for user 'fasd'. Reason: Could not find a login matching the name provided. [CLIENT: 10.80.62.89]
server=Yourservername,portnumber
You can put the above in your connection string
Problem was due to Customer configured another Default SQL port to use on SQL Management.
I have Windows 10 Pro machine with SQL Server 2016 Dev installed. There are two local user accounts on the machine: [WORK\admin] and [WORK\erop]. [WORK\erop] account was created at first without connecting to Microsoft. But later I connect it to my MS account. [WORK\erop] account was added to sysadmin role when installing SQL Srv.
Now I try to connect to SQL Srv instance with SSMS as [WORK\erop] but receive:
Login failed for user 'MicrosoftAccount\<my_MS_account>'. Reason: Could not find a login matching the name provided. [CLIENT: <local machine>]
and
Error: 18456, Severity: 14, State: 5.
which means "Invalid userid".
As I guess SSMS is launched under MS account and since MS account has no login on SQL Srv instance it refuses connection.
I executed
CREATE LOGIN [MicrosoftAccount\<MS_account>] FROM WINDOWS WITH DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english]
GO
ALTER SERVER ROLE [sysadmin] ADD MEMBER [MicrosoftAccount\MS_account]
GO
and everything is OK. But I wonder are there any smarter way to map MS_account to local user that has a login on SQL Srv instance?
I wouldn't call any solution smarter than yours, depends on your situation and what you want. But alternatively you could have reverted to a local user, assuming you don't care about the OneDrive and such functions.
Start > Avatar button > Change account settings > Your email and accounts > Sign in with local account instead.
But adding the login again is the smartest and easiest solution.
For those who tried the solution above but are still encountering this issue: change your connectionstring within your appsettings by replacing the Server=localhost value with the server name you see when logging onto MSSQL Management Studio.
SQL Server was installed on the local PC by User1.
User1 has now left the company and a new account on the PC was created called User2.
User2 cannot access the local SQL Server installation.
Is it possible for User2 to access the local SQL Server without reinstalling?
Here is the error:
Cannot connect to mydatabasename.
Login failed for user 'myuser2name'. (.Net SqlClient Data Provider)
Server Name: mydatabasename
Error Number: 18456
Severity: 14
State: 1
Line Number: 65536
For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=18456&LinkId=20476
The easiest way would be to log in via the "sa" account but I expect you don't have the password to this or it isn't enabled.
If you start the server in single-user mode you will be able to add additional users without reinstalling.
This MSDN page outlines all the steps but in brief they are
Stop all services for that instance (including Sql Agent and Integration services) using "Sql Server Configuration Manager"
Open up the properties window for the Sql Server instance you need to modify.
Add an additional startup parameter "-m"
Start the service (make sure you only start the Sql Server service)
Start SSMS using "Run as Administrator"
Connect to server using windows auth.
Add login.
Remove -m parameter from service and restart all services stopped above.
I am getting this error while trying to connect to the SQL Server.
Microsoft SQL Server Error: 18456
Can anybody tell me what the error code means?
If you're trying to connect using "SQL Server Authentication" then you may want to modify your server authentication:
Within the Microsoft SQL Server Management Studio in the object explorer:
Right click on the server and click Properties
Go to the Security page
Under Server authentication choose the SQL Server and Windows Authentication mode radio button
Click OK
Restart SQL Services
Check out this MSDN blog article from the data platform team.
You really need to look at the state part of the error message to find the root cause of the issue.
2, 5 = Invalid userid
6 = Attempt to use a Windows login name with SQL Authentication
7 = Login disabled and password mismatch
8 = Password mismatch
9 = Invalid password
11, 12 = Valid login but server access failure
13 = SQL Server service paused
18 = Change password required
Afterwards, Google how to fix the issue.
Before opening, right-click and choose 'Run as Administrator'. This solved the problem for me.
I have faced this issue.
Please look at the attached image,
Step 1: Go to server property
Step 2: Go to Security
Step 3: Change server authentication as SQL server and WindowsAuthenication mode
and restart your Sql server.
first see the details of the error
if "state" is "1"
Ensure the database is set for both SQL and Windows authentication under SQL server / Properties / Security.
for other state see the above answers ....
Just an update, here is the solution if anyone else has there error with a properly configured login:
If you're trying to connect using "SQL Server Authentication" then you may want to modify your server authentication:
Within the Microsoft SQL Server Management Studio in the object explorer:
Right click on the server and click Properties
Go to the Security page
Under Server authentication choose the SQL Server and Windows Authentication mode radio button
Click OK
Restart SQL Services
Check whether mixed mode authentication is enabled in you server->properties
Then create a login in the server->security
create an user for that login in your database
Then restart your server by right clicking the instance and select restart
If you change a login user credential or add new login user then after you need to log in then you will have to restart the SQL Server Service. for that
GO to--> Services
Then go to SQL Server(MSSQLSERVER) and stop and start again
Now try to log in, I hope You can.
Thanks
Just happened to me, and turned out to be different than all other cases listed here.
I happen to have two virtual servers hosted in the same cluster, each with it own IP address. The host configured one of the servers to be the SQL Server, and the other to be the Web server. However, SQL Server is installed and running on both. The host forgot to mention which of the servers is the SQL and which is the Web, so I just assumed the first is Web, second is SQL.
When I connected to the (what I thought is) SQL Server and tried to connect via SSMS, choosing Windows Authentication, I got the error mentioned in this question. After pulling lots of hairs, I went over all the setting, including SQL Server Network Configuration, Protocols for MSSQLSERVER:
Double clicking the TCP/IP gave me this:
The IP address was of the other virtual server! This finally made me realize I simply confused between the servers, and all worked well on the second server.
Right Click the User, go to properties, change the default database to master
This is the screen print of the image which shows what you have to check if you have the error 19456. Sometimes it default to a database which the user doesn't have permission
18456 Error State List
ERROR STATE ERROR DESCRIPTION
State 2 and State 5 Invalid userid
State 6 Attempt to use a Windows login name with SQL Authentication
State 7 Login disabled and password mismatch
State 8 Password mismatch
State 9 Invalid password
State 11 and State 12 Valid login but server access failure
State 13 SQL Server service paused
State 18 Change password required
Potential causes
Below is a list of reasons and some brief explanation what to do:
SQL Authentication not enabled: If you use SQL Login for the first time on SQL Server instance than very often error 18456 occurs because server might be set in Windows Authentication mode (only).
How to fix? Check this SQL Server and Windows Authentication Mode page.
Invalid userID: SQL Server is not able to find the specified UserID on the server you are trying to get. The most common cause is that this userID hasn’t been granted access on the server but this could be also a simple typo or you accidentally are trying to connect to different server (Typical if you use more than one server)
Invalid password: Wrong password or just a typo. Remember that this username can have different passwords on different servers.
less common errors: The userID might be disabled on the server. Windows login was provided for SQL Authentication (change to Windows Authentication. If you use SSMS you might have to run as different user to use this option). Password might have expired and probably several other reasons…. If you know of any other ones let me know.
18456 state 1 explanations: Usually Microsoft SQL Server will give you error state 1 which actually does not mean anything apart from that you have 18456 error. State 1 is used to hide actual state in order to protect the system, which to me makes sense. Below is a list with all different states and for more information about retrieving accurate states visit Understanding "login failed" (Error 18456) error messages in SQL Server 2005
Hope that helps
Also you can just login with windows authentication and run the following query to enable it:
ALTER LOGIN sa ENABLE ;
GO
ALTER LOGIN sa WITH PASSWORD = '<enterStrongPasswordHere>' ;
GO
Source: https://learn.microsoft.com/en-us/sql/database-engine/configure-windows/change-server-authentication-mode
First go to start bar then search local services
Then click on "view local services"
Then it will open service window then go to SQL Server(MSSQLSERVER) right click on it and click on stop and then again right click on it and click start. Now you can able to login and put your user name as 'sa' and password is your won password.
Please check to see if you are connected to the network if this is a domain member PC. Also, make sure you are not on a dual home PC as your routes may be incorrect due to network metrics. I had this issue when I could not connect to the domain the SQL windows authentication switched to the local PC account but registered it as a SQL authentication. Once I disabled my wireless adapter and rebooted, the Windows integration switched back to the domain account and authenticated fine. I had already set up Mixed mode as you had already done as well so the previous posts do not apply.
For me, it was wrong login and password.
I believe this can happen if you are trying to log in with a user that is defined in Active Directory, but attempt using "SQL Server Authentication" in the login screen. I do not know how to specify a different user with NTLM/Windows Authentication: When I click the Windows Authentication dropdown, the username and password is blanked out, and I can only log in as myself.
In my case multiple wrong attempts locked the account.To do that I had tried running the below query and it worked:
ALTER LOGIN WITH PASSWORD= UNLOCK
And make sure to set the option "Enforce Password Security" option for specific user to be unchecked by right click on Sql Server -> Properties.
SQL Server connection troubleshoot
In case you are not able to connect with SQL Authentication and you've tried the other solutions.
You may try the following:
Check connectivity
Disable Firewall.
Run PortQry on 1434 and check the answer.
Check the state
Try to connect with SSMS or sqlcmd and check the message.
State 1 is rarely documented but it just mean you don't have the right to know the true state.
Look at the log file in the directory of SQL server to know what is the state.
The State 5
What ? my login doesn't exist ? it's right there, I can see it in SSMS. How can it be ?
The most likely explanation is the most likely to be the right one.
The state of the login
Destroy, recreate it, enable it.
reset the password.
Or...
"You don't look at the right place" or "what you see is not what you think".
The Local DB and SQLEXPRESS conflict
If you connect with SSMS with Windows authentication, and your instance is named SQLEXPRESS, you are probably looking at the LocalDb and not the right server. So you just created your login on LocalDb.
When you connect through SQL Server authentication with SSMS, it will try to connect to SQLEXPRESS real server where your beloved login doesn't exist yet.
Additional note: Check in the connection parameters tab if you've not forgotten some strange connection string there.
Another worked solution for me.
serever->security->logins->new logins->General->create your user name as login name,Click sql server authentication add passwords
uncheck the password verification three checkboxes .
This will work.
Remeber to change the server properties ->Security from Server authentication to SQL Server and Windows Authentication mode
you can do in linux for mssql
change password for sa account
sudo /opt/mssql/bin/mssql-conf setup

I got this error after creating a new sysadmin user under my SQL instance.
My admin user was created under a specific domain
MyOrganization/useradmin
Using useradmin on a disconnected environment allows you to create other users using SQL Server authentication, but as soon as you try to login you get
Microsoft SQL Server Error: 18456
To fix the problem, try to connect again to your Organization network and create the user while you are connected and then you can get disconnected and will work.
I have faced the same issue. In case you see it, run this query:
DBCC FREEPROCCACHE
DBCC DROPCLEANBUFFERS
then it shows a 18456 error code.
Do one thing again run same query after reconnecting SQL server. It will work fine.
Click on "Options" and under "Connection Properties" specify the catalog/database name next to "Connect to database:". I got the error because this was set to <default> and I needed to specify the dbname.
Microsoft SQL Server, Error: 18456
I was getting an issue because I was entering the wrong password.
