Hi,
I have just installed Windows Vista and SQL Server 2005. When I try to connect to my local server with Windows Authentication, I get the follwoing message:
Login failed for user <user> (Microsoft SQL Server, error: 18456)
Any help please. Thanks.
I'm working on an ASP.NET project, and we're attempting to switch from SQL Server authentication to Windows authentication to connect to the database.
It works fine locally when I debug in Visual Studio, but when it hits the web server, I get the error: "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection."
IIS has anonymous access disabled, and Integrated Windows Authentication is checked. The web.config file has:
<authentication mode="Windows"/><identity impersonate="true"/>
The database I'm attempting to access is on a different machine than IIS, and the connection string doesn't contain a username or password, and has "Trusted_Connection=Yes", and "Integrated Security=SSPI".
From what I've been able to find online, I'm guessing the problem is due to IIS and SQL Server residing on different machines, but I'm not sure how to fix it.
Any ideas?
Hi,
I have created a Windows user login and have granted it the appropriate roles (including a revoke).
As a test I also created a standard user and gave it the same roles as above.
When I run a query against the revoked table, the results are unexpected.
The Windows user can run the query, and the standard user gets a permissions error (which is what i expect).
Does anyone have any ideas as to what is happening here? I am still confused.... Does it have anything to do with the public permission that much be granted?
Thanks
Is it possible to create a windows authentication login for each of the computers on my network that will connect to sql server. I am developing a program that will be installed on multiple computers and we do not want to actually have to log in to sql server since we will have to log in to the server before opening the program and we dont want to have 2 logins. I would like to use windows authentication so that I do not have to program multiple connection strings in my program so that if more than 1 person accesses the database at the same time it will not cause a problem with using the same login. Is this possible and if so how would I go about setting up the logins. I am using SQL Server 2005 and XP SP2

I have a problem with sql server 2005 express, when i try to connect to an sql database it says login: is not a trusted connection to an sql database. I have gone into reg edit and changed the authentication setting from windows oly mode 1 to mixed mode 2. It still has the same problem, does anyone have any idea what the problem may be?

Hello All,
I'm hoping someone can help me with this puzzle.
Most logins I've created have been SQL Server authenticated. I assign the login newEmployee to a role existingRole, and ensure the role has the required permissions. This didn't seem to be rocket science....
My company has been provided with an application with a SQL Server back-end. My instructions were to create a Windows authenticated login and give it full access to the database. I followed the above principles, but running the application, the user got the error -
SELECT permission denied on object 'sysobjects', database 'databasename', owner 'dbo'.
So I decided to try the simplest possible scenario to make it work:
I've created a login DOMAINewEmployee with Windows authentication.
DOMAINewEmployee has been granted access to databasename.
By default, DOMAINewEmployee is a member of Public.
Public has been granted all available permissions on all objects.
ie... grant all on userTables to public
........grant all on sysobjects to public
........grant all on otherSystemTables to public
etc.
Running the application, the user still gets the above error. I'd send the problem back to the vendor, except if I've logged onto the PC as DOMAINewEmployee, querying -
select * from dbo.sysobjects
via Query Analyser produces the same error message. (An equivalent error message is produced when querying a user-created table).
To compare, I then created a login newEmployee2 with SQL Server authentication.
newEmployee2 has been granted access to databasename.
select * from dbo.sysobjects
runs successfully from Query Analyser (as to any queries on user-created tables).
What else is required to grant access to tables from a Windows authenticated login?
( What really scares me, is that the application will run if I make the Windows authenticated login a member of server roles System Administrator and Database Creators, then the application will run - but I don't want this to be the permanent solution. Even after doing this, the above query still fails in Query Analyser for that login, suggesting that there is something wrong with how I configured the permissions. )
Any help would be appreciated.
Thanks.
Kim.
In my DB (SQL 2012) one windows authentication is created automatically and a schema is created exactly automatically that this user is owner of this schema. (e.g the user is domainx and schema exactly domainx).
I created a DDL Trigger on my DB to find out who and how it is created , but I didn't get any useful information.
I change the owner of schema that I can delete the schema and after that delete the user, and sometimes because the user is owner of a service , I have to alter the owner of the service to DBO and delete the user , but again and again exactly this user and schema (e.g domaninx ) are created as soon as I delete it.
I have read these topics : [URL] .... and [URL] .... but can't solve my problem.
I get this error when trying to connect. I'm using the sa id and password for all of my odbc connections. It fails when trying to connect to this one but it's ok on a couple of others I've set up with the same id etc.
Where is this "" coming from and how to avoid it in the future?
I've removed and recreated the connection to be sure that I didn't actually type that in as the id....hey it's monday...it could happen.
We have see login failures for windows accounts. Below is the error message.

HI all,
I would like to ONLY allow using SQL Server authentication and restrict Windows Authentication. At the moment, i set the security to "SQL server and windows authentication". Now, even though i set the password for "sa", i can ignore the SQL Server authentication and just use Windows authentication to manipulate database objects???
can anybody give some suggestions to restrict windows authentication and allow sql server authentication?.
Thanks in Advance
Best Regards
Ihsan
I recently attempted to change the password of the sa login. There were no issues while updating the password neither did I get an error when I logged in as sa. Everything appeared to connect and I was able to query a database. However, an error was logged (error 18456 severity 14 state 8) as though I did not log in successfully. Even though I can connect successfully, I don't like having these misleading errors in the SQL Server Log.
View 5 Replies View RelatedOracle and Teradata are able to capture the windows/client login that connects to their database with a functionnal ID.I've searched around and I don't think MS SQL can do this...I administer SQL 2014 server and also SAS Enterprise guide product. I've created sql server logins for several teams so everyone shares the same sql server login which is used to bind the SAS library to my SQL server database.
However, when looking at activity monitor, I can't drill down to which user is executing a particular query. I only see the SQL login which is share amongs 200 other folks.On the other hand, when they connect from SAS to Oracle or Teradata, I can see the shared login + additionally their windows NT login used to connect to SAS which is awesome....they can't fool me by using a shared/funcionnal ID....i still see who's using that ID...
Hi--
I am building an intRAnet website using windows authentication for website access and SQL Server access ( Trusted_Connection = true ).
In IIS I have these settings:
Allow Anonymous = unchecked (false)
Windows Authentication = Checked (true)
Digest windows = checked (true)
In my Web.Config file:
authentication="windows"
impersonate="true"
allowusers="*"
When I pull up the page these are my credentials:
Security.Principal.Windows: mydomainmyuserid (this is correct what it shows on my page)
Me.User.Identity: mydomainmyuserid (this is correct what it shows on my page)
Threading.currentThread.currentUser mydomainmyuserid (this is correct what it shows on my page)
So the ASP.NET page recognizes it is me and my domain. However, when i click a button to pull some data from a database I get the error message: Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
My data access on SQL Server works fine. The weird thing is when I debug on my machine it pulls data fine. but when I copy the files to the windows 2003 server it doesn't work.
Do i have to do something with delegation?

I get this error when I try to connect to my SQL Server with JDBC:

but I checked the password is correct.
Any ideas? Thank you in advance.
A user is trying to connect to a server via windows authentication from SQL management studio on her desktop.
The log file on the server gives:
Login failed for user: domain1user1
Error : 18456, Severity: 14, State: 11
The strange thing is that the user in the error above is not the user she's trying to connect as (domain2user2, say).
user2 can remote desktop to the server and log in there.
I know this state implies "Valid login but server access failure".
Has anyone run into this, and what more information would be useful to know? Thanks!
I just upgraded SQL Server 2000 to 2005 without any errors. Afterwards, I tried registering with sa and it failed. I registered with another sysadmin login to get into most of my databases, but I need sa to work for my backup software Idera SQLSafe to login to the database.
Does anyone have any experience or recommendations? I know my password is correct.

Hi
I am new to SQL server and I have been trying hard to make a client computer to remote connect to a SQL express database on host computer
I have a VB6 application that can connect to SQL server database LOCALLY without problem:
Connection String is:
my_connection.ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MyMushroom;Data Source=LAPTOPSQLEXPRESS"
I have followed instruction on enabling remote connection function from this blog:
http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspx
I then try to run the same app from the client computer, it gives me:
Login failed for user 'LAPTOPGuest'.
After looking up the web for solution, I found that I can test the connection from the HOST computer in this way:
C:Documents and Settingskit>sqlcmd -E -S laptopsqlexpress
1>
2>
The test is successful
Now I run the same command on the CLIENT computer
C:Documents and SettingsKit>sqlcmd -E -S laptopsqlexpress
Msg 18456, Level 14, State 1, Server LAPTOPSQLEXPRESS, Line 1
Login failed for user 'LAPTOPGuest'.
Now I can sure that from the client computer it cannot make a connection to it, then I look at the errorLog from my host computer
2006-08-13 21:41:00.34 Logon Error: 18456, Severity: 14, State: 11.

Valid login but server access failure
It tells the connection string and SQL Express seem to be set up properly but the server access failed the remote connection
I have previously had SQL Server 2000 installed. I uninstalled SQL 2000 before I install SQL express but somehow the SQL Server Service Manager is still running at startup, and C:Program FilesMicrosoft SQL Server80 and its files are still exist after uninstallation..... Could this be a problem?
The Knowledge base suggestion on "enabling remote connection" is very simple and I do not understand why it is so difficult to me just to make a remote connection test work..... please, I need your help.
Recently, one of my clients began receiving this error. My team gave them sysadmin permissions, but this is terrible practice. I have read into disablying simple file sharing, but I don't even think I have the option to do it. I look in mycomputer > tools > view and don't see any option for this. Besides, the problem just started occuring recently, within the last week. The server is a cluster with veritas clustering and the edition is sql server 2000. Has anybody ever had a problem like this and have a good fix?
Thanks for any help in advance...

Hi,
I am trying to create a linked server between 2 SQL Server 2005 boxes.
When I create the linked server I specify a login for the connection.
The strange part is that I get the following error when it goes to test the connection:
The test connection to the linked server failed
Login failed for user 'Domainuser'. (Microsoft SQL Server, Error: 18456)
I can use the SQL mangement studio to conenct to the database using this same login.
The login has all the server roles assigned to it also.
Can anyone shed some light as to what may be the problem?
Thanks,
I am getting this error when I try to switch the SQL Express installation from Windows to SQL Auth. "Operation is not valid due to the current state of the object".

Hi,
I wanted to check the asymmetric key option in sql 2005. I copied the books online code for creating a asymmetric key and then used this key for creating a login. Now when I try to login without entering any password I am receiving 18456 error. I would like to know what I am missing here. If I use CREATE LOGIN from asymmetric key or certificate how do I login and with what credentials. Do I need to provide any password.CREATE ASYMMETRIC KEY PacificSales09
WITH ALGORITHM = RSA_2048
ENCRYPTION BY PASSWORD = 'bmsA$dk7i82bv55foajsd9764';
GO
CREATE LOGIN asm FROM ASYMMETRIC KEY PacificSales09;

We are looking at developing an SQL Server 2005 Database and I would like to use Windows Authentication rather than SQL Server Authentication to connect our client app.
In our development environment, we have two Servers, one being used as a file server and the other as an SQL Server. We have now set up a domain using the file server as the domain controller. (We had previously been set up to use a workgroup).
I have set up an active directory group called SqlDevelopers and added an active directory user called Jonathan to it.
On the SQL Sever, in management studio, I have set up a new server login which uses windows authentication called DomainSqlDevelopers. I used the GUI to verify I could see the domain and the group.
The default database is set to a test database on the server. A user in the test database is mapped to the DomainSqlDevelopers and given the Roles dbo, db_datareader, db_datawriter.
To test the log in, on the server, I logged out as administrator and in as Jonathan. I could successfully access the server through management studio using windows authentication.
However, if I log in as Jonathan on my client PC and try to access the SQL Server using management studio and windows authentication, I have problems.
The first time I try I will get a timeout error. If I try again will get either:
Login failed for user ''. The user is not associated with a trusted SQL Server connection
Or
Cannot generate SSPI context
I can€™t determine any pattern to which of the above errors I get.
However, if I log in as administrator on my client PC, I can connect to the server using management studio and windows authentication.
Sounds like Active Directory/Domain or other Network issue (Not really my area). I would be grateful for any help.
Thanks,
Jon

(Using win2k, sqlserver2k, framework 1.1)
I have an fairly data-heavy application that uses Windows authentication (Trusted connection/aspnet account) to connect to Sql Server. The site uses IIS basic authentication.
On the dev server everything works fine but when I move to the live server things get strange and it starts to crawl along. (Pages load OK but then it just crawls as it loads the datagrids etc. Sometimes it brings back incomplete/incorrect data )
BUT When I use Sql Authentication to connect to Sql Server and there is no problem at all!
Ok, there is something obviously wrong with the live server (which is identical setup to dev)but I dont know where to start.
Any ideas??
