What Authentication Mode Is Best For Me?
Oct 4, 2005
Hi,
Were working on a Smart Client application. Our customers will have .Net Windows forms on their computers that will access SQL Server data on our server.
I've read that Windows Authentication is the most secure authentication mode. However, since our customers computers are not on our network it would be impossible to use Windows Authentication. We'll have to use Mixed Authentication. I just wanted to confirm this in case my understanding of the authentication modes is wrong.
Thanks,
Chris

Hi Everyone
I changed the authentication mode from SQL Server Authentication into Windows of my application (Web application - ASP.NET 1.1, SQL Server 2000, C#). I changed the SqlServer into Windows only mode authentication.
The SQL server now contains all the "windows users" as users of the database (Logins as well as Users).
But I faced the problem of 'login failed for NT AuthorityNetwork Service'. So I added the Network Service as user. The login problem is disappeared, but when I'm tracing through the SQL Profiler I can see only the Network Service as user and not my windows usernameSQL server login name.
what should I do for displaying the windows usernameSql login name in the profiler instead of "Network Service". Please help me.
Thanks in advance

2. In Object Explorer right click on first (Server) node
3. Select 'Properties'
4. Select Page 'Security'
5. set 'Server authentication' to 'SQL Server and Windows Authentication mode'
6. press OK
7. in popup window fill password ******** and press OK
8. get error message ''operation is not valid due to the current state of the object. (Microsoft.SqlServer.Express.SqlManagerUI)
How correctly to set above Server mode ?
Why I get the error message and how to solve it ?
Thank you

How can I change the authentication mode for sqlexpress without going through the UI? I looked at the docs for sp_configure, dmo and smo but I may have missed it. I'd like to be able to run a script that changes the authentication mode of an installed sqlexpress instance from windows only to moxed mode.
Thanks

There are two different tasks I would like to serve with SSEE, both case the users are changing seats. I think SQL Server Authentication would be better for lightweight user change but I have read everywhere that Windows Authentication Mode is the preferred way to go.
Is there any significant weakness in SQL Server authentication mode - security, work with stored procedures (CLR) or anything?

First post, so greetings!I've been using ASP.NET 2 authentication from an MS SQL 2k5 database now in the web application for my company's customer accounts (file serving, custom webreports, etc). There is currently no support for employees through this web app, but in our plan to go paperless it's become of interest to let the employees access much of their information through the same web portal. The catch is, I'd rather not make them have to use two accounts (one for their domain authentication and one for their web authentication). It's already taken a lot of conditioning to get them to memorize a single username and password.So what I really need is the single Login.aspx page to accept both ASP.NET logins and Domain digest logins, and the Domain digest login needs to be HTTP based (not named pipes). Is this possible at all, and if so, is it possible without making an isapi filter? After all, Microsoft Office Outlook Web Access is served by the exchange server and accepts active directory passwords. So how could I do authentication in this way, and if so, is it possible to have the Outlook Web Access form be accessible from the same session as that of my web server? Thanks, I surely hope someone can help. . . -Brandon

I'm getting the message
Your account information could not be verified
Press Ok to return .....
For setup to verify your credentials the servcies must be startable, connectable, and you must be a SQL Server administrator.
I'm running and instance of sql server called development if that helps any.

I am trying to create a query that can determine if a user id is using mixed mode/windows/both authentication. I need to do this so that it can run on both sql server 2000 and 2005, meaning I can't use any of the sys.* views. Is there a single query could use for both systems?

I'm having a little issue here with the MSSQLServer service which installs as part of the BlackBerry Enterprise Server. I can connect to it and run queries on it via Query Analyzer, but when I attempt to have a PHP script query against it, I get an error stating that the login failed because the user is not associated with a trusted SQL connection (severity 14). I've seen this before with other servers, and it was always a result of the server not being in mixed authentication mode.
So the question is this: How do I change it? There doesn't appear to be an Enterprise Manager or anything equivalent installed. Digging through the SQL Server folder, the only thing I saw that might have been useful is the SQL Server Network Utility located at Program FilesMicrosoft SQL Server80ToolsBinnSVRNETCN.EXE. This utility appears to only let me disable/enable protocols however, nothing about authentication.
I checked the Service Manager as well and didn't see anything of use there. Any ideas how I can do this?

If i create a database in sql express in windows authentication mode, the database owner is in the format of 'MACHINENAMEUSERNAME'. If i connect this database to iis server i got login failed error message.
This is my connection string in my web.config :
Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=True;Initial Catalog=dbsgh;Data Source=software92sqlexpress
I solved this problem by creating a login in sqlexpress called 'software92/aspnet' and creating a user for my database named aspnet under 'software92/aspnet' login. Then i changed the usrename in directory security of my iis virtual directory to 'software92/aspnet'.
This solves my problem. But i think i m solving this problem in a wrong way.
I think i should create that database under default owner. Who is the default owner?
I dont know the correct procedure to solve this.
Please help.

Hi there,
I am implementing SSRS 2005 Sharepoint integration mode in a stand alone server and we are having problems with basic authentication.
When the MOSS web application and the Report Server application is in Windows Integrated authentication Everything works fine and we can upload and view reports in the sharepoint site.
But when we switch the MOSS web application into basic authentication and RS stays the same with windows integrated authentication the reports in sharepoint throw 401 unauthorized errors. It looks like the error occurs when accessing the _vti_bin/ReportServer/ReportService2006.asmx web service??
Anyone have any fix on this????
Does SSRS 2005 Sharepoint integration mode support Basic authentication???

Hello everyone,
We have SQL server 2000 on windows 2000. From our desktop MS Access was connected to database through ODBC. Since yesterday (after our consultant had updated another asp application in the same server) we are getting €œSQL Server Error: 18452. €¦.. Login failed for user €˜(null)€™. Reason: not associated with a trusted SQL Server connection. €œ
The consultant saying he did not touch any settings on server (?). And the problem is even server€™s security property shows it has mixed mode authentication. But I cannot connect to server even through my SQL server enterprise manager in windows authentication mode. I can connect if I use SQL server authentication. Through ODBC I can connect also and test fine, if I use SQL authentication. But the Access application wouldn€™t connect using SQL authentication in ODBC.
So, can any one help me to find out what else could be done to make sure that the server is going to accept windows authentication. I€™m thinking any other settings or registry change €¦ etc. Please help.
Thanks

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 :-)

Just like with Access DB, can we set password for database in SQL Server 2005 Express ?
Reason to do so is, user with Login having sysadmin previliage can acess all databases in SQL server.
so just want to restrict database access to only those users who knows the password.
Is there any possible solution ? Pls comment.
Thanks.

We have reports in SharePoint integrated mode which are really slow when compared to native mode. I have been asked to research and give info on what exactly causes the delays.

Hello,everyone!!
There is a query which when executed in the grid mode(ctrl+d) takes approx 0.02 seconds(about 21,000
rows) But when I execute in the text mode, it takes about 0.40 seconds!!
Why is this difference?
Also, when the records from this table are read from a VB application, they are equally slow (as in the text mode!)
Why is it so slow on the text mode & relatively faster in the grid mode?
Has anyone got any idea on ‘Firehose’ style cursor ?(which may speed up access of data in the VB application)
Rgds,
Adie
