SQL Server 2014 :: Can Get User Windows Login When Using Server Login Authentication

Apr 26, 2015

Oracle 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...

Intranet, Windows Authentication, Sql Server Login Failed For User '(null)'

Mar 31, 2006

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?

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

Login Failed For User '(null)' Error When Trying To Use Windows Authentication

Feb 6, 2006

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?

Login Failed For User '' ..... Sql Server, Error: 18452 (The User Is Not Associated With A Trusted SQL Server Connection)

Nov 7, 2007

Hi

Last week I was receiving an error when trying to connect to two of our seven sql servers from my laptop via my domain admin account. The only fix was to have my laptop rebuilt and everything re-installed.

Today however another administrator is starting to have the same problem but to only one of the seven servers!
When that administrator uses my laptop with her domain admin account it works!?

What could possibly be going wrong with our laptops? We have not installed or changed anything.

The full error message we see:

Login failed for user ''. The user is not associated with a trusted SQL Server connection. (Microsoft Sql Server, Error: 18452)

The error being logged on the server: (two errors are logged each time)


SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed. [CLIENT: 53.35.165.148]


Login failed for user ''. The user is not associated with a trusted SQL Server connection. [CLIENT: 53.35.165.148]

Login Failed For User 'testuser'. The User Is Not Associated With A Trusted SQL Server Connection.

Aug 19, 2006

Hi,
I have a copy of VS2005 and i have installed the Microsoft SQL Server Developer Edition
I am trying to do my first connection using ASP.net (yay for me...) and it has failed...with this error..Login failed for user 'testuser'. The user is not associated with a trusted SQL Server connection.
 
can someone please point out why? yes i know that the error seems pretty straight forward but how do i fix it? like how do i make the user a trusted server connection? where do i do it? and what are the steps? the user is an administrator and by rights should have all access to everything....
 
connection string
 
SqlConnection MySQLConnection;              MySQLConnection = new SqlConnection("server=cmptrname\databsename;uid=testuser;password=password;database=mytest");
 
btw while your reading do you have any examples of opening a db with the connection string in the web.config file? because i get some error "connection string has not been initialised"  using the
system.Configuration.ConfigurationManager.AppSettings.Get
i though i would stick to the top code first before i tackled the web config error first....
 
Thanks heaps

Error Login Failed For User ''. The User Is Not Associated With A Trusted SQL Server Connection.

All the research I found dealing with this problem is that the solution is to set SQLserver to mix mode.  I have SQL server already set to mix mode. I am not sure what else to do. Has anybody run into this problem?

I am trying to do a unattended upgrade of an MSDE 2000 named instance, say MyInstance, to a SQl Server Express Advanced edition. The set up is Mixed Mode Authentication. ( I can't use Windows Authentication for business reasons).

My questions:
- Can I use SQL Authentication?
- Where am I going wrong?
- I know the error message says to use Windows Authentication but I don't understand why I am I forced into using that.

Any insightsopinions will be highly appreciated.

Login Failed For User ''. The User Is Not Associated With A Trusted SQL Server Connection.

Oct 23, 2006

I've seen many, many, many, many posts regarding this topic - but none have been able to fully explain nor fix my problem.I've developed a security solution according to Scott Gu's guide and it works great - but only on my local machine running VWD and SQLExp2005. Once I move this application it completely breaks in the productions environment.  Today I managed to get it halfway there. I created a SQL login and changed my web.config to use these credentials - now the web application will come up, but none of my links (that are role based) are displayed - most likely because i'm authenticating as the SQL credentials instead of me. So I switch it back to windows authenticated, as it is on my laptop, and it breaks again. Please tell me theres a way to get this working in production and Scott's fantastic tutorial hasn't wasted me 2 weeks of work. Here's the exact error I get when using Integrated authentication:
Server Error in '/Contracts' Application.

Hi
I'm making a website and will upload it next via ftp but i need to access the local server for database retrieval from this website. i'm doing so first time so not sure about its working and isues. Through google search and from forums i collect some info to work on it. now i have made a connection string to access remotely that gives the following error when i make the connection open
 "Login failed for user ''. The user is not associated with a trusted SQL Server connection."
the local server use the windows authentication mode or may be the mix mode.
Please any one can help me about this issue and further information related to it. and one more question, how much time a page takes to load while getting 600 records from a table in local server.

Login Failed For User ''. The User Is Not Associated With A Trusted SQL Server Connection.

Jan 29, 2008

Arrgh!  I've check and to make sure SQL Server and Windows Authentication option is selected.  The user has Grant access to connect to database engine and Login is enabled...and also has database read/write privs.  I can login using the username/password from Mangement Studio Express, but I can't from my app.  Here is my web.config:
<connectionStrings>    <add name="CPT_ConnectionString"          connectionString="Data Source=192.168.1.40ccsql1;Integrated Security=SSPI;"         providerName="System.Data.SqlClient" />  </connectionStrings>  <system.web>    <identity impersonate="true"></identity>  </system.web>
The only thing I can think of is that my app is using a DSN to connect to the database.  Any ideas?
Many thanks,
Mark
