Using C# To Access SQL Server At Another PC With Windows Authentication

Oct 8, 2007

Brief Description: I would like to use C# to write a program to access a SQL Server instance which is at another PC and using Windows Authentication. (I know how to use SQL Server Authentication, but I need to use Windows Authentication only.)

Detailed Description:
1. I have two PCs, and I would like to write a C# program in PC1. to access SQL Server at PC2 with Windows Authentication only.

2. I installed Microsoft Dynamics POS system. I install the POS Database with Windows Authentication only at PC2, but then I can install POS at my PC1, and when I set up the connection to the SQL Server, POS will pop up a dialog to ask me the username and password. I can just use the PC2's windows user account to login. Then POS can work fine. I would like to do the same just like what they did.

3. I tried the following code at the PC2 (the same PC as the SQL Server running), and it is running fine. But if I copy the same program and run it at another PC, then it will pop up a "Logon failuer: unknown user name or bad password.".

Microsoft.SqlServer.Management.Common.ServerConnection myServerConn = new Microsoft.SqlServer.Management.Common.ServerConnection();myServerConn.LoginSecure = true;myServerConn.ConnectAsUser = true;myServerConn.ConnectAsUserName = "username";myServerConn.ConnectAsPassword = "myPassword";myServerConn.ServerInstance = "myPCName\mySQLInstance";myServerConn.Connect();


Please help! Thank you!

IBMDASQL OLEDB Linked Server Access Denied Using Windows Authentication

May 15, 2007

I have a linked server defined on a SQL Server 2005 SP2 standard edition server using the IBMDASQL OLEDB driver. The linked server has been defined and working for months when used from a SQL Server authenticated session. I started converting our developers to Windows Authentication and access to the linked server is denied when used from a Windows Authenticated session. Here are the error messages:



Msg 7399, Level 16, State 1, Line 1

The OLE DB provider "IBMDASQL" for linked server "DB2ARUBA" reported an error. Access denied.

Msg 7350, Level 16, State 2, Line 1

Cannot get the column information from OLE DB provider "IBMDASQL" for linked server "DB2ARUBA".



The linked server security is defined to login to the IBM iSeries using a fixed user and password regardless of the login using the linked server.



In order to analyze the problem, I created one sysadmin SQL Server authenticated login and one sysadmin Windows Authenticated login. The Windows Authenticated login refers to a domain login having administrator priviledges on the local SQL Server box.



So, when I connect to SQL Server using the SQL Authenticated login, a query against the linked server works. When I connect to SQL Server using the Windows Authenticated login, the exact same query against the linked server fails with the messages above.



Does anyone know why?

Unauthorised Access Via Windows Authentication

Mar 13, 2008



Hi Guys,

My boss is concern that when using Windows authentication, a user can access any database that they have the rights too, using any SQL tool, and make unauthorised changes. He thinks that using SQL authentication is better because the username/password can be hidden from the user. (Access to the database is controlled by our applicatoin.)

Could someone knowledgeable in this are please comment.

Many thanks

Remote Access Using Windows Authentication

May 22, 2015

After 2 days of reading everything on the net about setting up Remote Access of my SQL 2012 Express using Windows Authentication I'm still not able to connect from a remote client onto my SQL Server Database Engine. I can get connected if using SQL Server Authentication. I have set all the parameters to allow access (read and tried everything from this site: URL.... but when I try using SSMS from the remote client to login I get Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452).I've disable the firewall (Even though I have put in rules to allow port 1433 and UDP port 1434). Nothing is allowing me to connect. I've have tried every solution listed and got nowhere. My network is very simple with only three computers connected via a Linksys router (Two running Windows 7 the test client is running Windows 8.1). I can shared files and folders between all. Each computer only has one user defined (default admin user).

I need to make this work as I have to document it for other end users who will be using an application I created that requires an SQL Database and it needs to be accessible by other users on their network.

Report Manager With Forms Authentication. Report Server With Windows Authentication.

Feb 1, 2008

Hi.

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?

New To MS SQL Server, Need Help With Windows Authentication

Oct 21, 2006

I am new to the whole ASP .NET scene, so my knowledge is very limited, and if I’m not clear enough please let me know. I am reading a book published by APress about ASP .NET with C# and I am at the point where I get to begin working with data (fun!!).  The problem is that I’m not able to connect to the SQL Server.  I have Server 2003 and SQL Server 2005 running on a separate machine than the computer that I use for development – the server is named THESERVER, the SQL server is named THESQLSERVER, and the computer I use for development is my laptop named MYLAPTOP. So here’s my connection string (I put this in my web.config XML file):<add name="Pubs" connectionString="DataSource=THESERVERTHESQLSERVER; Initial Catalog=pubs;Integrated Securit=SSPI"/>  Now here’s what my book reads:  For Windows authentication to work, the currently logged-on Windows user must have the required authorization to access the SQL database.  This is all it says about Windows authentication because the book assumes that I am running MS SQL Express off localhost. Questions: Does the book mean that I will have to add a user to my server for my laptop?  If so, how do I log into this user using the connection string?What does it mean by “the current logged-on Windows user”?  Is that referring to the user on my laptop, or a user on the server? I’ve been reading around trying to find more information on exactly how Windows authentication works, but I keep coming up dry.  I know that much of this is probably trivial to a lot of you, which is why I am asking because it isn’t to me.  Well, thanks in advance for any help that you can provide me.

Apr 26, 2005

I have an asp.net page which accesses a sql server database (on another server).
I am trying to use impersonation to impersonate the domain user accessing the page and use the credentials to access the sql server using a windows login. I have windows authentication checked in IIS settings am using the following web.config:<configuration>
  <system.web>
    <authentication mode="Windows" />    <identity impersonate="true"/>
    <authorization>      <allow users="*" />    </authorization>
    <customErrors mode="Off" />
  </system.web>
</configuration>
I can connect fine when i open the page on the IIS server but from other machines, whilst logged in as the same domain user I get the error:
Login error failed for user ''.
Anybody know what the problem might be?

Windows Authentication Vs SQL Server

Jul 20, 2004

Hello,

I'm writing some software for clients and the connection is done via de username passwd methode, not windows authentication. One of the salespeople is creating FUD now, talking about a "major security leak" because, if someone has the username / password, he can view the data in the mssql database. ( seems normal to me for a username/password combination - winNT or not - but this news can be shocking to the uninitiated)
Is there any paper on his comprehensionlevel that deals with this issue?
Or you've got an opinion on this?

Thanx for any pointers,

Windows Authentication With IIS And SQL Server

Sep 15, 2005

Hi,

We are changing our web application to use Windows Authentication instead of SQL Server Authentication.

Initially, we added the IUSR_MACHINENAME user to SQL Server. This works ok when SQL Server and IIS are both running on the same server.

However, this won't work if SQL Server and IIS are on different servers on the same domain.

After doing a lot of research on the internet, it seemed that the answer was to create a user on the domain and use that user in IIS as the anonymous user (and give that user the relevant rights on SQL Server).

However, I've seen other comments in articles on the internet saying "Running any web service as a domain user is ill-advised".

We are using ASP rather than ASP.NET. What is the correct (and most secure) way to go about this?

Best

Matt.

SQL Server - Windows Authentication

Feb 24, 2007

Ours is distributed WinForms application. Application logon is using Windows integrated authentication. As a best practice I would like to use Windows authentication for SQL Server connection. This means that when the user logons on to the workstation, the user will gain access to the application and also to the SQL Server. But there is a requirement that the end user cannot directly login to the database. So if the user tries to access Sql server database through some client tools I shouldn't allow that. How can I achieve this?

Thanks

Sql Authentication = Fast./ Windows Authentication = V.slow!

Mar 25, 2004

Hello,

(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, 2006

Hi 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, 2006

Hi 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!

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?

Windows Group Authentication In SQL Server

May 23, 2008

Does anyone know how windows authentication works in SQL Server 2005 with regard to group membership? If a user is a member of two NT groups that have the same permissions in SQL then which group will be used to authenticate their login? The reason I ask is that logins have default languages associated with them so if a user is a member of NT group A with a default language of British English and is also a member of group B with a default language of US English then which one will be used and will it be the same one every time?

Question On Connection To SQL Server Using Windows Authentication

Mar 5, 2004

I have a domain user account through which I can log on a machine. The machine allows me to use this domain user account to create DB in SQL Server using windows authentication. How can I define a connection string to connect SQL Server? My connection string is like:
string str = "server=(local);uid='"+userName+"';password='"+password+"';database='master';connection timeout=15";

This one works on another machine where I use SA account. But this one does not work using windows authentication. I tried to use domainnamemyname as user name, but failed.
Could any one give me some suggestion?

SQL Server Windows Authentication Passthrough Problem

Mar 6, 2007

I am running my laptop separate from a domain with a local user that has the same username as password as my domain account.

Under Windows XP -> User Accounts -> Manage My Network Passwords I could passthrough my domain credentials to allow myself access to the SQL Server using windows authentication. This is confirmed to have worked with both SQL Server 2000 and SQL Server 2005 from Windows XP.

My current laptop is now running Windows Vista and this method seems to work fine for network access, but does not seem to work for SQL Server authentication using Windows authentication and I receive the following error.

Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection. (Microsoft SQL Server, Error: 18452).

Any assistance would be appreciated.

Windows Authentication Fails If IIS And SQL Server Are On Different Servers

May 9, 2007



Hi

I am using SQLXML 3 on a Windows 2003 server Running IIS 6.0. I used SQLXML configure IIS Support to create a virtual directry on this server to connect to MS SQL Server 2000 instance running on another windows 2003 server.

Configurations for the virtual directory are

1. Used Windows integrated authentication.

2. Created template for executing the stored procedure.



When i try to access the DB Server through a browser i am prompted to provide for Windows authentication. Even if i provide the domain user that has administrtive rights on both the server i am getting a response.

ERROR: 400.100 Bad Request

HResult: 0x80046000
Source: Microsoft SQL isapi extension
Description: Invalid connection settings: access denied



If from MMC i change the properties of the virtual directry to enable anonymous acess using the cridentials that i mentioned earlier, everything is working fine. I have been searching the net for 2 days and tried everything that i could find but still i keep getting the same error.

Any help will be highly appretiated.

Windows Authentication Failed For SQL Server 2000

Feb 27, 2008



Logins failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
(microsoft SQL Server, Error: 18452)


Hi Guys.

How are you,
its something very complicated to understand my issue.
i am receiving the above error message when i tried to login with using windows accout to connect to SQL server Instance using client tool.

ok Let me start step by step.
1) Initially we have one box using windows 2000 (OS) and having SQL Server 2000.
2) Here on SQL Server instance i have created windows account login and gave permissions to one of the database on that instance.
3) this windows account is in the right domain and also in the same domain
4) when i right click on Management Studio on the different machine --> Run As--> enter the windows account --> select the above Sql server instance.then connect
5) Here i am not able to connect to the sql server.
the below error generates when i press the connect button
Logins failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
(microsoft SQL Server, Error: 18452)

if we gave the full permission to connect to box with this windows account then i am able to connect the sql server instance, otherwise its not allowing me to connect to the Sql server instance.


we have another box using windows 2000 (OS) and having SQL Server 2005.
i have followed the same as above with same windows account login.
Here i am able to connect to the SQL Server Instance and also this windows account donot have permission to connet the box.

Anybody have idea about this issue???
if the SQL server 2000 doesnot have the option to connect remotely. unless that windows account have the full permissions to box.
if you have any white paper please let know.
i really appreciate for your effort, if you dont understand please let me know.
thanks so much.
