.NET Framework :: Windows Authentication With Different User
Sep 24, 2015
Below is the scenario
I have 2 users.
User1 : have sql rights on database but dont have rights to login into windows
User2 ; have rights to login into system but dont have access rights to database
Now I have windows application and i have logged into system with User2 and want to run windows application with the rights of User1. How can i achieve this.
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.
I'm almost sure that it's not possible, but I wanted to ask in case that I'm missing something.Is it possible to get the Windows user when someone logins using SQL Server Authentication? I know how to get the hostname, but I can't find how to make the next step.By the way, do sleeping connections affect performance? Would they consume resources such as RAM or network?
I have a website written in asp.net and the current DATABASE logins do not use windows authenticaton. They are for online use only with a username and password. I'm trying to run my program locally on my machine and access the database locally. This is very frustrating. I'm able to connect to my database, but I can't login to it. Here's my connection string from ym webconfig file: <add name="sqlConnectionString" providerName="System.Data.SqlClient" connectionString="Connect Timeout=8; Initial Catalog=linkexchanger; Data Source=SCOTSQLEXPRESS; "/> I have the MSSQL engine running and I have connected with the SERVER. My database is in my directory tree of Microsoft SQL Management Studio Express. The server is SCOTSQLEXPRESSI have attempted to add a login to my sql database by right clicking on the security folder to create a new login. My understanding is that under windows, I don't need a uid and pwd in my connection string . Thus I tried removing all of this just as you see above, and I get an error message every single time I try to create a login with windows authentication. Can someone please explain how I make this work? Thank you. Scot
Is there a way to connect to database using Windows authentication as a different user than what you've logged in with to your desktop?
For example:
I log on to my desktop as mydomainme. I'm developing queries using Management Studio against a database (on another server) where mydomainme doesn't have access, but the admins have granted access to mydomainJobs1. I have the password for mydomainJobs1, and I'm hoping I can connect to the database using that account without having to log-off my local desktop as mydomainme and then re-login using mydomainJobs1.
The analogy in the file/share-permissions world would be using "net use" from a command prompt:
net use \SomeServer /User:mydomainJobs1 jobs1password
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?
I'm trying to connect to a SQL Server 2005 database engine on a local network server. When I am presented with the Connect to Server dialog box, if I select Windows Authentication from the Authentication drop-down, the User name & Password area is grayed out and unusable. The domain user account I'm authenticated with is visible, but grayed out, and the password field is blank and unusable. I'd like to be able to connect as described in help:
User name
Enter the user name to connect with. This option is only available if you have selected to connect using Windows Authentication.
I can connect with either SQL Server or Windows authentication... but with Windows Authentication I'd love to be able to type a specific user name to select with :-)
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?
Would be interested in any advice or comment on the issue we are experiencing with SQL 2005.
In order to test some DTS package migrations, we simply created a DTS package on SQL 2000 (using Export) to copy all database objects from one database to another.
Then we restored the source database on SQL 2005 server, migrated the DTS package, and tried to execute it.
The package migrated 'fine', ran part way, and then failed. Since then we have been unable to connect to the server (Database Engine, or Integration Services) using Windows Authentication. (Error 18456, Sev 16, State 11).
We can connect to the Database Engine using SQL Authentication (but not to Integration Services which only allows Windows Authentication).
We have been able to replicate this consistently - every annoying time we've tried it!
(Reinstalling SQL Server does 'fix' the issue ... until you try a similar package again).
Hi there,I have installed MS SQL Server 2005 on my machine with windows authentication. But now I want to switch the authentication mode to SQL Authentication. I am unable to switch, I can’t find the proper way to do so here in 2005.Could any one help me in doing this?Thank you,-Ahsan
(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.
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?
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.
I just upgraded from Windows XP Pro to Windows Vista Bussiness and tried to reinstall SQL Server 2005 Developers Edition. After the installation i downloaded (using microsoft windows update) and installed all the service packs for sql and vista available.
My problem is when i open sql server management studio and try to connect to my default instance using windows authentication and database engine, an 18456 error occurs.
I enabled all the protocols and all the ports I disabled windows firewall and antivirus (eset nod32) I installed all service packs available I have also installed Visual Studio 2005 without installing sqlexpress
But nothing happens!
Please i am very desperate, any information will be gratefully accepted.
This is my installation Information

Does anyone know if I have created a replication using SQL Server 2000 (sp3a), .Netframework 1.0 with Pocket pc Sql Server CE 2.0 will work or not in pocket pc windows mobile 5.0 environment (with the .netframework for pocket pc(netcf.core.ppc3.arm.cab) and sql ce file (sqlce.ppc3.arm.CAB) installed in pocket pc)?
I have it working in pocket pc Windows mobile 2003 version. But, after I tried to install the exact same cab files and system into Windows mobile 5.0, the replication fail.
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.
For using different services of SQL SERVER 2005 which is better... Windows Authentication or SQL Server Authentication? what are the advantages and disadvantages of both?

I wanted to install SQL Server 2005 Express Edition, instead of installing .Net Framework 2.0, I installed .Net Framework 3.5. When I tried to install SQL Server 2005 Express Edition I received the following error:
SQL_ERROR (-1) in OdbcStatement::execute_batch sqlstate=42000, level=16, state=2, native_error=7404, msg=[Microsoft][SQL Native Client][SQL Server]The server could not load DCOM. Error Code: 0x80071cec (7404) Windows Error Text: Source File Name: libodbc_statement.h Compiler Timestamp: Wed Jun 14 16:28:15 2006 Function Name: OdbcStatement::execute_batch@sysdbupg.sql@56 Source Line Number: 91
I then decided maybe I do need .net framework 2.0, but when I try to install it it says it's already included with the OS.
But the "Programs and Featuers" only list .Net Framework 1.1 and .Net Framework 1,1 Hotfix (KB92979).
I uninstalled .Net Framework 3.5 and tried to install .Net Framework 2.0 again, but it still says it's included in the OS.
After uninstalling .Net Framework 3.5, I tried to install SQL Server 2005 Express Edition, but still received the above error message.
Is .Net Framework 2.0 included with Windows Vista Home Edition?
If it is, any ideas in solving the Server 2005 Express Edition installation error?
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...
I wonder if it is possible to set forms authentication for report manager but leave report server "as it is". I need to authenticate users from external LDAP and can't use windows authentication for report manager, but I would also like to leave report server open for anonymous users. In that way authenticated administrators could create reports which anonymous users could read.
I tested the Security Extension Sample and got it working when I rewrote the authentication part with my own LDAP authentication.
If I have understood correctly, the report manager is just application inside report server so is it possible to use forms authentication with one application but still leave the report server with Windows authentication?
I am in the process of rolling out a sql server 2005 enterprise install and had a question regarding authentication. We will be providing sql hosting for a number of groups on our campus, many who are not using our campus-wide active directory, though they all have an AD account.
Windows authentication via the management studio appears to use your AD authentication tokens and will not allow them to enter a username/password combo. Is there any way to configure this?
I would like to use our campus AD for obvious reasons but if there is a requirement for passing tokens this isn't going to work right? It's also going to make database mirroring more of a challenge.

My SQLExpress seems to be set for windows authentication and not sql server authentication ... I am not quite sure why it is set to windows authentication - I installed this with Visual Studio 2005 and it just seemed to be set that way.Am I able to change this - if I choose sql authentication when connecting I get an errorIf someone could answer this point I would be most grateful !!Patrick
In an effort to eliminate the need to code accounts and passwords into the VB Com calling stored procedures, I would like to use Windows Authentication. I have setup the account that the com is running under to have access to the database. How does this change my connection string. Do I just drop the account and password parameters or do I need to let it know somehow that I want to use Windows Authentication?
I'm having problems with windows authentication. I'm new to using using Microsoft SQL Server. I just migrated from powerbuilder 8 to powerbuilder 10. I'm using OLE DB and can't get the windows authentication to work within the application. Can anyone help....
Hi, I am wondering that do we need to create the separate login at SQL SERVER (server) for all the user using the application for the windows authentication?
How do the windows authentication works? I have a apllication and SQL SERVER (SERVER) running on the same machine. Any user from the same domain can access the application. Application is interacting with the DB through Windows Authentication. Now my question is whether do we need to authenticate each user from the domain at the DB level. That is to craete the login id for all the user for windows authentication.
I remove the windows authentication from enterprise manager. and Now i want to re-assign the the windows authentication . so can i do it from query analyzer.
