Authentication An Application Using Windows Integrated Authentication
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!

Using SQL Authentication And Windows Integrated Authentication Concurrently
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.

Windows Integrated Authentication - Domain Controller
If my SQL Server authentication is windows integrated authentication, whenever my application makes a connection to SQL server does it contact the windows active directory domain controller to authenticate the windows user account? How does windows integrated authentication work in the background?

SSRS And ASP.Net And Windows Integrated Authentication Failure In Internet Explorer
I have a very confusing problem that I'm going to attempt to relay concisely: I have a LAN on which I'm running an Intranet web site built in ASP.Net 2.0 and using SSRS / Sql Server 2005 on the same server. The name of the box is "warehouse" or "warehouse.mydomain.us." When I ping "warehouse," I get a response from 137.86.166.8, as I should. Likewise, I get a response from 137.86.166.8 when I ping "warehouse.mydomain.us." If I do a "ping -a" on 137.86.166.8, it correctly resolves to "warehouse.mydomain.us." Based on the facts presented in this paragraph, I believe that my DNS is working as expected. Using IE (6.0.2900.2180.xpsp_sp2_gdr.050301-1519) with "low" security settings, I navigate to http://warehouse.mydomain.us/lex/ (Lex is the name of the app) and it authenticates me to the index page (which calls the SSRS web service to get and display a list of available reports), except that I get the login prompt three times. If I hit F5 (refresh), I get three more login prompts and then I get a 401.1 error. From this point, no matter what I do, I can not see the index page again without closing and restarting IE. I know that IE only passes credentials to certain sites, so I add my domain (http://warehouse.mydomain.us/) to the Local Intranet list ( Tools->Internet Options->Security->Local Intranet->Advanced) and then I can refresh and see my index page once, but I still get 3 login attempts and then the same thing happens -- I refresh and go through 3 logins and then get a 401.1. If I now change my address bar to read http://137.86.166.8/lex, I get a single login and it works like a champ. This makes me think that there's a DNS problem, so I open up Mozilla Firefox and wouldn't you know it -- Firefox works like a champ all around -- one single sign-in, it keep credentials between Lex and SSRS, and it appears to use the DNS correctly. However, I can't use Firefox because I can't get any of the SSRS reports to look like they're supposed to in Mozilla-based browsers. Argh. I have set my IE securtiy settings to "Low." I have added the primary domain to the Local Intranet list and also to the Trusted Sites list (but you can't do both at the same time). I have even added the internal IP to my "hosts" file. Does anyone know anything that might be a help to me in getting this figured out? Other notes of interest: My machine is an XP machine, but is not on the domain, but I do have a valid domain login that I use and it works in Firefox without problem.

When MOSS Integrated SSRS,Trusted Account Works Well? Windows Authentication Gets Error?
This subject appears several times,But I still can't solve this problem,because this problem is difference with others! I'm having trouble getting SQL Server 2005 Reporting Services and MOSS 2007 working together in integrated mode. Here's the background: WSS3.0 and Sql Server 2005(64bit) with SP2 is installed on SERVER1(64bit). This Sql Server hosts both the MOSS content database as well as the reporting services database. MOSS 2007 is installed on SERVER2(32bit) I've installed all the required components for both boxes with no installation errors I use domain accout as the Service Accounts; When I set Authentication Mode to "Windows Authentication ",I get a 'HTTP 401 Unauthorized' error when using the 'Set server defaults' link from MOSS 2007 Central Administration. But it's strange that when I set Authentication Mode to "Trusted Account",everything works well. BTW,There is not any Event viewer's message left! Thank for your help!

Switching From SQL Authentication To Integrated Authentication?
Hi,I'm using SQL Server 2005. My Connection String looks like that at the moment: <add name="LocalSqlServer" connectionString="Data Source=xx;Initial Catalog=xx;Persist Security Info=True;User ID=xx;Password=xx" providerName="System.Data.SqlClient"/> Now I'd like to change this kind of authentication to Integrated Windows AuthenticationI added the WorkerProcess IIS_WPG to the permitted Users but it didn't help.Changed the Connection String to this:connectionString="Server=xx;Database=xx;Trusted_Connection=True;"All I'm getting is that my NetworkService is not permitted to access DB when I try to connect to the DB in ASP.NET.How can I properly configure that?

Sql Authentication = Fast./ Windows Authentication = V.slow!
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 Windows Authentication V/s Mixed Authentication
Hi, 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. Thanks Santhosh

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

Sql Authentication Vs. 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. Thanks

Problem Accessing Sql Server Through Integrated Authentication
I run Reporting Services on a Windows 2003 Server running the Web Service as "NT AuthorityNetworkService". If I create a report using a database connection to a remote SQL Server 2005 using "Integrated Authentication", it works as long as I look at that report on the (reporting Services) server itself. Selecting the Tsql function SUSR_NAME() in my query/report shows that I am effectively identified as myself (a domain user), so Windows Authentication is fine. If I try to browse to my report from another machine, I get an error as follows An error has occurred during report processing. * Cannot create a connection to data source '...'. Looking in the Reporting Services log, it looks like I "am" identified as "NT AuthorityNetworkService" when running the same report. Why is Windows Authentication not applying here? Any idea what I configured wrong? Many Thanks Eric

RS 2005 SP2 In Sharepoint Integrated Mode With Forms Authentication
Hi, We can't get RS to work in Sharepoint integrated mode with a Sharepoint web application that uses forms authentication. Each request to a report server item (new or existing) fails with the following error: An unexpected error occurred while connecting to the report server. Verify that the report server is available and configured for SharePoint integrated mode. --> The request failed with the error message: -- <html><head><title>Object moved</title></head><body> <h2>Object moved to <a href="/_layouts/login.aspx?ReturnUrl=%2f_vti_bin%2fReportServer%2fReportService2006.asmx">here</a>.</h2> </body></html> --. We created several web applications and we always end up with this error. If we revert to Windows authentication (NTLM), everything works fine. The problem is the same as the one described in the following thread, at the difference that in our case it never worked (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1357851&SiteID=1). The last post in the thread states that forms authentication is NOT supported in Sharepoint integrated mode. This is not correct in my opinion. All the Sharepoint integrated mode documentation states that forms authentication can be used. Officially only RS custom security extensions are not supported with the Sharepoint integrated mode with . Our configuration: 1 WSS 3.0 box 1 RS2005 SP2 box 1 SQL 2000 box All services run under different domain accounts. Any ideas? Regards, FK

Reporting Services 2005 In SharePoint Integrated Mode With Forms Based Authentication
Well, I have SQL Server 2005 SP2 Reporting Services installed and configured in sharepoint integrated mode, so I am deploying reports in sharepoint libraries. Also I configured sharepoint to use forms authentication with builtin AspNetSqlMembership provider, but after this action I couldnot open reports through sharepoint library, instead of this, error was displayed mentioned below. I searched and found hotfix Cumulative Update 3 build 3186 for this issue, request it from microsoft support and applied it, but nothing has changed! Error I have been experiencing is following: An unexpected error occurred while connecting to the report server. Verify that the report server is available and configured for SharePoint integrated mode. --> The request failed with the error message: -- <html><head><title>Object moved</title></head><body> <h2>Object moved to <a href="/_layouts/login.aspx?ReturnUrl= %2f_vti_bin %2fReportServer%2fReportService2006.asmx">here</a>.</h2> </body></html> I continued to dig and find out that this hotfix should update Microsoft.ReportingServices.SharePoint.UI.WebParts.dll from version 9.0.3042.0 to new version 9.0.3180.0, but when I checked file version after applying hotfix, it remained the same as was before i.e. 9.0.3042.0. Apparently this cumulative update does not fix this issue. anyone has any idea how to solve it? Thanks in advance. sorry for my poor english :-)

Report Server Authentication Errors (custom Security Authentication)
This has been plauging us for a year now and still haven't figured it out. We wrote a custom authentication extension based completely off the example code MS provided with SQL Server 2005. We upgraded to SP2 thinking it might fix the problem. Nope... here is what happens... you go to our server and there is a pause for about 5 seconds then the login page shows up I login with a user and pass then it just sits there with the loading icon spinning in IE. Eventually (this happens every time!) it comes back with Code Block "The report server is not responding. Verify that the report server is running and can be accessed from this computer. " If you refresh that page it loads fine! ok seems odd... went ot the LogFiles folder and there is a minidump and a bunch of logs around the time that happened.

Windows Authentication
Hi all,You're all stars, really helpful. Maybe one day i can be :)My question is regarding the authentication in Windows SQL Server 2005.We have setup a sa account. We purchase software from a third partythat runs on it. Before their software logs on the sql server as sa,and does its own access control, windows autentication takes over. Itslogs users on correctly i guess, using a more secure link via thedomain. However, I am probably blind, but where can we assign rights toeach domain user? I.e. stop XXY dropping tables, but allow ABC to droptables?I had a brief look through but could not find anything that stood out,in the SQL Manager.ThanksDavidP.S This is SQL Server 2005 Workgroup edition running on a 2003 windowsdomain server. Alongside a SQL 2000 server, which is running fine usingsa accounts.For those in the same timezones as me... have a good evening.

I checked the servers' properties of that Ican and can't see, but couldn't find any difference. Can someone giveme a direction that will enable me to debugg?If the servers are not in the same domain, how can I see them (windowsauthentication) from the same PC (client)?For some SQL server I even can not login via windows authentication atterminal server.

Windows Authentication
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. Thanks, Rahul Jha

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? Thanks, Ken Nicholson

Windows Authentication With OLE DB
My organization is in transition of converting from SQL Server 2000 to SQL Server 2005. Conversion from Visual C++ 6.0 to Visual C++ 2005 is done. The converted Visual C++ code has OLE DB and has only native code(== no managed code). The OLE DB uses user name and password information to log into SQL Server 2000. Microsoft recommand to use Windows Authentication for security reason. I was informed that Basic Authentication, SQL Server Authentication, or Mixed Authentication allows OLE DB connectivity with user id and password. However, I have tried but have not figured out how to use same OLE DB with user Id and password information to access SQL Server 2005 with Windows Authentication. Is it possible to use Windows Authentication with OLE DB connectivity with user id and password? If so, I would greatly appreciate sharing your findings. Thank you very much for your help in advance.

Windows Authentication
We have an application that uses SQL Server 2005 (Express) as its database server. We have SQL server and the application database on our server. To setup the application we need to point it to our database from the clients and specify authentication as either SQL server or Windows Integrated Authentication. We chose Windows Integrated Authentication. This works fine for an administrator user but for a standard user with non administrator privileges , authentication fails and we cant access the database. The client is running Visa Business with UAC on. If I run the application as adminisrator and enter the administartor username and password then I can connect otherwise it is rejected. How can I can configure SQL server to allow non administrator users to access it using Windows Integarted Authentication. The server is running SBS 2003 Thanks

Windows Authentication
I've got an application that's supposed to use a combination of Windows authentication and Custom authorization, here's how. Only the administrator can add users, venues, and booking types. In addition, only the administrator can reset a booking password on the bookings table and/or form. I (as the current administrator) want to be able to add a user and grant him/her permissions (either as admin or just user). Admin access: add new users, venues, booking types, and reset booking password which will be used to grant permission to change booking details such as time and date. When the administrator adds a new user, there's an option (a field called admin on the user table) on whether or not to give the user admin rights, if yes the user is added to both the admin role and the user table 'Normal' user access: add and/or change own booking and change other user's return time and date provided a password is correctly provided. Does not even have to know that there's a user, venue, and a booking type table. I've read about Windows authentication on the MSDN library but I seem to be getting nowhere and just have no clue where to start. Help appreciated!

New To MS SQL Server, Need Help With Windows Authentication
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.

AUTHORIZATION With WINDOWS AUTHENTICATION -- HELP!!
i want to implement authorization with windows authentication and don'thave the slightest clue of how to do this implementation. the basicwindows authentication for this .NET application is already setup. myproblem lies within my inability to manipulate the username captured inthe authentication process and my knowledge of how IIS is involved.specifically, i have the following questions:1) what object(s) can be used so that the user's username can bemanipulated for the authorization process?2) in order to apply roles, do the users need to be placed in groups inIIS? if so, how does this work?3) is all the code that the application uses for roles in web.config?or does global.asax play a role in this matter?4) does the web.config file know to communicate with IIS because theauthorization type is set to windows?5) once authorization is in place, can a section of an .aspx file bevisible to a group or can only entire files be secured for a group?as you can see, i'm trying to figure out the relationship betweenauthorization and windows authentication so any help would beappreciated.thanks,johne: Join Bytes!

Windows Authentication Vs SQL Server
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, W13

Windows Authentication Issue;
Hi All, My Delphi application is connected to MS SQL Server 2000 database.The connection is establised with SQL Server authentication from the Delphi Application. My problem is , When the SQL Server's Authentication mode is changed to "Windows Only", I change the Connection String attribute to Trusted Connection in which Im not specifying the UserId and Password as shown below. 'Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=TestDb;Data Source=dev-pc006;Use Procedure for Prepare=1;Auto Translate=True;Workstation ID=dev-pc003;Use Encryption for Data=False'; Now the connection is establised and I get "Invalid Object" error if the user id is not prefixed to the objects in the Delphi application's queries. Is there any way to change the login/user after establishing the connection in Windows Authentication mode. Thanks in advance. regards, Hari Haran Arulmozhi

MS SQL Query For Windows Authentication
Hi I am working on analyzing the network traffic for MS SQL Server. The setup for generating the traffic is as follows: Server: MS SQL server version 2000 Client: SQL Query Analyser version SQL 8.00 Operating System: Microsoft Windows Server 2003 The issue here is, by default Kerberos authentication is enabled on the above operating system. But I want to enable NTLM authentication on Windows Server 2003 inorder to capture a trace and check whether it contains NT authentication packet embedded in the TDS login packet as described in the TDS document. I disabled Kerberos from the windows services and enabled NTLM from services. But it did not work out. Also I enabled NTLM by editing the Group Policy from “Active Directory Users and Computers” by going in “Administrative Tools” on Windows. But still it did not work out. In both the above cases, the packet had Kerberos authentication only when I selected the option “Windows Authentication” in the Query Analyser while logging in to the MS SQL Server. Any references/inputs which answer this issue would be appreciated. Thanks, Shama
