SQL Server 2014 :: Can Get User Windows Login When Using Server Login Authentication
Apr 26, 2015Oracle 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...
Login Failed For Sql Authentication
May 24, 2006I've developed an ASP2 application. Locally, everything was fine. However, when I deployed it on a remote server. I got this error:
Login failed for user 'domainuserx'.
My connection string is:
connectionString="Data Source=ServerName;Initial Catalog=Aspect;User Id =domainuserx;Password = abc"
I'm quite sure that connection string is fine. I need to mention that whenever I try to connect to the remote server from my client by the Sql authentication, I get the message that login failed for this user. But when I try to connect by windows authentication, it works and there is no error.
I asked the administrator, and he told me that Sql Server authentication is in mixed mode.
So, I really can't figure out what is the problem
ASP.NET Login Authentication Using SQLExpress
Feb 21, 2008I recently installed Web Developer Express and SQLExpress and cannot get connected to the SQL to create the aspnetdb.mdf database file. I ran the utility aspnet_regsql.exe with the switches -E -A m but got a message stating that it could not connect because remote access might be disabled. I enabled remote access using both TCP/IP and pipes even though only local access is required. It still returns the same error message. The machine.config and web.config files have the correct entries for ConnectionStrings and Providers to specify SQLProviderMembership.

Feb 18, 2002Hi,
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
How To Create A Windows Authentication Login
Jan 16, 2007Is 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

Permissions Not Effective For Windows Authentication Login
Jul 7, 2007Hello 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.

SQL Login Windows Authentication Error: 18456

Forms Authentication --&&> Redirect To Login Page
May 8, 2008We've successfully set up SSRS with forms Authentication (yea - wasn't easy!)
If we browse to the default web site, we get the login page. Once we authenticate, we can move around the site and run reports.
If however, we try to access a page (other than the login page) while we're not authenticated we get an exception instead of being redirected to the login page:
Object reference not set to an instance of an object
Microsoft.ReportingServices.UI.GlobalApp.Application_AuthenticateRequest(Object sender, EventArgs e)
If we set the Reportmanagerweb.config file to use Windows authentication, we get a 401 Access Denied page instead.
My first inclination would be to override the Global.asax file for SSRS, swallow the exception and redirect to the Login page. Not sure how to do this since the Global.asax.cs page isn't in the folder (I assume the compiled version hidden away somewhere).
It's not just the intial login either, timeouts are especially frustrating because, instead of being redirected to the login page, the users get the exception.
Any idea what might be causing the exception in the first place?
Thanks!

Login Failed For User '(null)' Error When Trying To Use Windows Authentication
Feb 6, 2006I'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?

Intranet, Windows Authentication, Sql Server Login Failed For User '(null)'
Mar 31, 2006Hi--
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?

Windows Authentication - Cannot Generate SSPI Context - Login Failed For User ''. The User Is Not Associated With A Trusted SQL
May 29, 2007
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

Sql Authentication = Fast./ Windows Authentication = V.slow!
Mar 25, 2004Hello,
(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??
Using SQL Authentication And Windows Integrated Authentication Concurrently
May 15, 2006Hi all,
I've got two applications which both have a database on my MS SQL 2000 server. The problem is, one application must use Windows Integrated Authentication (which it is currently using and cannot be changed) whilst the other application which I'm trying to configure must use a SQL password.
Since the server has already been configured to use Windows Integrated Authentication for the existing database and application, how do I configure the other database to use the SQL password?
Thanks.
Authentication An Application Using Windows Integrated Authentication
May 12, 2006Hi all,
My work is using a shared application
which accesses a MSSQL 2000 database. To access the application, the
folder on the Windows 2003 Server is shared and users can access the
folder through a shared drive.
For the application to access the
database, it uses an ODBC connection to the MSSQL server which
originally used the SA password.
We have recently switched to using
Windows Integrated Authentication because we believe it offers a
higher level of security. However the only way in which we have been
able to enable this is to add the windows users to the SQL server.
The problem with this is that the
application sets permissions for individual users on what records
they can see within the database. We have found that by adding the
windows users to the SQL Server, they can bypass the permissions the
set by the application by simply using any application that can use
an ODBC connection, such as Enterprise Manager, and see all the
database.
One way around this would be to set up
domains of users with access privileges to the tables which reflect
the permissions set by the application, and configuring a view of the
data so they may only see the records that they have permissions to.
However to do this would require a high administrative cost to ensure
that changes made in the application are reflected in the privileges
of the SQL server.
Instead, is there a way the SQL server
can authenticate that the ODBC connection is coming from the correct
application using Windows Integrated Authentication?
This would allow the applcation to
determine security, and stop users from connecting to the SQL server
using other applications.
Alternatively, can the SQL server,
using Windows Integrated Authentication, also ask the application to
supply a username and password?
Any help with this matter would be
greatly appreciated.
Thanks!

SQL Server Authentication Vs Windows Authentication

View 3 Replies View RelatedUsing Windows Authentication V/s Mixed Authentication
Dec 18, 2006Hi,
Say, I have configured my SQL to use Mixed Authentication. Now, I have a applicaiton which uses my SQL Server. The application just creates a database in SQL Server and uses the database to store its information.
This application also has a SYSTEM DSN under ODBC through which it accesses the database. For the application to access this database, should I only use SA (as my SQL instance is configured to use Mixed Authentication) or can I use Windows Authentcation too...
If I should only use SA, do we have a documentation which talks about this.
