How Authentication Works For SQL Services
Jan 14, 2008
Hi All
may be this is not the right place to put this question but still i am trying.
can some there please let me know how authnetication wotks for SQL Services. i mean when we configure SQL Services run under some domain account or local system account where and how it get authenticated that these services can run under particular account. or what rights need to assign to account in order to run SQL Services if that doesn't have sys admin rights or it has to be sys admin. why i am asking this question because i come across problem where SQL Service run under domain account but SQL Agent not.

I can run the following query in Management Studio, but get the error listed below when I run it from the data tab in Reporting Services:
declare @starttime as datetime
declare @endtime as datetime
declare @timezone as integer
declare @date as datetime
set @timezone = 1
set @date = '5/1/2007'
set @starttime = dateadd(hh, @timezone, @date)
set @endtime = dateadd(d, 1, @starttime)
select @Starttime, @endtime from site
Error Message:
TITLE: Microsoft Report Designer
------------------------------
An error occurred while executing the query.
The variable name '@starttime' has already been declared. Variable names must be unique within a query batch or stored procedure.
------------------------------
ADDITIONAL INFORMATION:
The variable name '@starttime' has already been declared. Variable names must be unique within a query batch or stored procedure. (Microsoft SQL Server, Error: 134)

OK
------------------------------
What I am trying to accomplish is the ability for users to select which time zone they want the data in the report to display in. To do this, I created a timezone parameter that has the offset from Central Time (which is how all data is stored in our database).
Any help would be greatly appreciated!

I have a very basic / stripped connection manager with only one property (SSIS 2012). It works fine in design time (you can open the connection manager editor and change the value), but in runtime it only works in 32bit mode. The runtime-validate-method does work, but if everything validates OK then in 64bit it throws an error when you run the package:
Exception deserializing the package "The package failed to load due to error 0xC0011008 "Error loading from XML. No further detailed error information can be specified for this problem because no Events object was passed where detailed error information can be stored.". This occurs when CPackage::LoadFromXML fails.
The 2 VS projects are .Net 4 class library projects with the Build Platform on "Any CPU"
I only add references to:

Can i have a combination of sources some with Unique Identifiers and some without?
I need to know what happens when I have option “Create Code values automatically” selected for the entity and same time pulling Unique Identifier for other sources in same entity stage table.
When we select option “Create Code values automatically” for the entity we creates, then during load from external source to MDM stage we don’t send any values to MDM stage “Code” field and in next step when we execute the stored procedure to load the data from MDM stage to MDM model, it assigns the Code values to each record in MDM stage and MDM model.
I need to know whether after executing the store procedure, will it assign Code values for only NULL records in MDM stage and not give us any error for the records that already have Code values present in MDM stage.

I have an acctest server (XX-ATS-ASSHP102) running SSRS, SQL DB Engine & SSAS. I'm trying to configure NATIVE SQL Reporting Services to use a data source with Windows Integrated mode towards a SSAS cube on the same server. When I use the servername (or 127.0.0.1) it works perfectly. But when I use the DNS name bidb.acctest.internal it fails with the error "The connection either timed out or was lost.". The profiler on SSAS says "anonymous login" so the Kerberos login is broken at some point.The weird thing is that this works perfectly in production environment, but I've missed something in the ACCTEST environment.The SPN for the serviceaccount running SSAS has correctect SPN:s:
MSOLAPSvc.3/bidb.acctest.internal
MSOLAPSvc.3/bidb.acctest.internal:MSSQLSERVER
MSOLAPSvc.3/XX-ATS-ASSHP102
MSOLAPSvc.3/XX-ATS-ASSHP102.XX.XXXXXXXXXXX.net
MSOLAPSvc.3/XX-ATS-ASSHP102.XX.XXXXXXXXXXX.net:MSSQLSERVER
MSOLAPSvc.3/XX-ATS-ASSHP102:MSSQLSERVER
The SSRS account has delegation with "any service". No account has the "sensitive" flag.DNS names are A-records, except the hostname for the SSRS site which is a c-name, but it's identical in production.The "impersonate client after login" and "replace token" permissions are correct in the policy.The rsreportserver.config says:
<Authentication>
<AuthenticationTypes>
<RSWindowsNTLM/>
</AuthenticationTypes>
<RSWindowsExtendedProtectionLevel>Off</RSWindowsExtendedProtectionLevel>
<RSWindowsExtendedProtectionScenario>Proxy</RSWindowsExtendedProtectionScenario>
<EnableAuthPersistence>true</EnableAuthPersistence>
</Authentication>
both in production and in acctest env..

Hello,My boss wants me to create a front end webpage for our ReportingServices reports that customers can log onto through a webform. I'm aPHP programmer, so I'd rather do this site and the authentication inPHP than learn .NET. The main problem I see is finding a way to passthe authentication to Reporting Services so that when a user runs areport, they are not asked to enter their password a second time.I don't even know where to start researching this problem... I've askedin PHP forums and they passed me to you guys. Any ideas?Andrew

Hi,
I've changed from Visual Studio 2003 to Visula Studio 2005 by using now the MS SQL 2005 Express Advanced Edition.
As I wanted to deploy another report suddenly it asked me for an authetication for the ReportServer ?
Well, no problem, I thought and looked into the authentications in IIS, but no one of those is working.
Where the heck do I have to look ?
Thx for reply.
Andreas
P.S. Using on backend site RS Enterprise Edition SP1 and changed for developing reports from VS 2003 to VS 2005 with reporting services.

I am using Reporting services 2005 and have enabled forms authentication using the example found in:
'C:Program FilesMicrosoft SQL Server90SamplesReporting ServicesExtension SamplesFormsAuthentication Sample'
This works correctly without SSL, but when I enable SSL I get an error when logging in. The symptoms are as follows. I can login to the reporting server (in my case <server>/ReportServer2) directory, but when I login to the report manager (in my case at <server>/Reports2) I get the following error:
'The underlying connection was closed: An unexpected error occurred on a send.'
Can anyone suggest why I might be getting this error?
Thank you,
Graham

Hi,
I am new to Reporting Services. I want to use Reporting Services 2005 in our application.
My custom web application is on one machine and Reporting Services 2005 is on other machine. I am using Forms Authentication and using Single Sign On for login
If my custom web application and Reporting Services are on same machin I can get "Authentication Ticket" issued by ReportingServices2005 to the Report server.
But in this case I am not able to get "Authentication Ticket" on Report Server since it is on other machine.
I am using ReportViewer control in my web application to display Reports and using LogonUser method to get the Authentication Ticket.
How can I pass CookieAuthentication ticket from my Custom Web Application to Report Server?
Is there any work around to pass Authentication Cookie across Domain or any other solution for this?
Regards
Amit

I setup CRM 4.0 in one domain with a domain service account. SQL Reporting is located on the same machine using the same service account. SQL is on a different machine. These are in the same single domain forest which has a two way trust relation with another domain of a separate single domain forest. Both domains are W2k3 Native Mode.
The CRM application allows access to users in both domains. The reports are generated with accounts in the first domain where CRM and SQL Reports is located but not for users in the other domain. The CRM's report viewer window displays "The report cannot be displayed."
The following are events that are related to the error:

The take away from the events is either the SQL Reporting or CRM is attempting to access the SQL service with the Anonymous account. I expect it's SQL reporting because the CRM application is not having problems letting in the other domain users. The problem occurs only on reports.
I tried the following:
1. Applied the steps in the CRM Planning Guide for "Taks for a native mode domain with users in a mixed-mode domain." This adds the other domain users to a domain local group. Then assigns Browser access to the SQL reports and SQL database access to the group.
2. Set the CRM server to be trusted for delegation (kerberos only)
3. Created SPNs for http/crmserver domaincrmservice and http/crmserver:5555 domaincrmservice and http/crmserver.domain.local domaincrmservice and http/crmserver.domain.local:5555 domaincrmservice
Any suggestion?

I hope someone can help.
I'm working on a web project that will display the reports in an iframe to the user. When I was using windows security It worked perfectly.
Now my boss wants me to use form based authentication instead that can authenticate against our current Active Directory. This is working perfectly and does authenticate correctly. The only problem is that when I load a report in the iframe http://myserver/reportserver/myreport-blah reporting services prompts the user to enter in windows credentials. Is there anyway to pass my form credentials to the report server so that the user doesn't have to log in again.
Both the report server and the web app are on the same server BUT in different virtual directories.
PS: I tried using the reportviewer control but it does not display things correctly. For example, I have use a multi select dropdown on the reports and it messes up the drop down when the user only has 1 selection (hiding the selection). If the user has more than one selection the drop down uses scroll bars. I would use the reportviewer control if it displayed exactly like it does when using alternate URL method.
Any help would be MUCH appreciated!
Thanks!

This is a subject that has been brought up before but I have not seen a definitive answer/solution.
We have implemented a custom authentication extension (forms authentication) for reporting services and it has been working just fine under "normal" conditions; "normal" being users logging in, viewing reports, and then moving on.
Recently some reports were created by our report group and they contain Dundas gauge controls for "dashboard" style reports. These reports are meant to be up all day and they post back every few seconds because the data they present is mission critical.
This of course exposed the inability of the reportviewer control to stay in the context of Report Manager when it comes to the cookie exchange and authentication thus resulting in the following error:
<html><head><title>Object moved</title></head><body>
<h2>Object
moved to <a
href="/ReportServer/logon.aspx?ReturnUrl=%2freportserver%2fReportExecution2005.asmx">here</a>.</h2>
</body></html>
I created a quick ASP.NET web application and added the reportviewer to it, implemented IReportServerCredentials and the report came up as expected but behaved the same way as it did in Report Manager. Same with a Windows Forms application.
Increasing the cookie timeout in the forms authentication tag is an option, but not an attractive one. Extending the reportviewer control is also an option, but I don't know if that is a good candidate right now because I don't see anything extensible yet.
Is this just the nature of RS with custom authentication or is there a viable solution out there right now?
Any and all answers are much appreciated and I thank you in advance.

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.

I've gotten to the point of publishing the new reports on the SSRS server and have run into the following problem.
I use a field in the primary report with the "Go to report" action to open up another report (also published) for more details. It works properly from within ReportBuilder (2.0) using the report server and I can go to and from the secondary report as I expect. Its passing the correct parameters to the second report and its runs.
But when I use the reports from the SSRS web, the Go To link no longer works. Mouse hover shows its still a link but clicking goes no where. I can run both reports independently from SSRS and they still work.
I've tried this in IE and Chrome with no luck in either. I also poked around at Compatability view and popup blocker but nothing made any difference.

I'm having a strange problem with this but I know (and admit) that the problem is on my PC and nowhere else. My firewall was causing a problem because I was unable to PING the database server, switching this off gets a successful PING immediately. The most useful utility to date is running netstat -an in the command window. This illustrates all the connections that are live and ports that are being listed to. I can establish a connection both by running
telnet sql5.hostinguk.net 1433 and
sqlcmd -S sql5.hostinguk.net -U username -P password

Both these utilities show as establishing a connection in netstat so I am able to connect the database server every time, this worked throughout yesterday and has continued this morning.
The problem is when I attempt to use SQL Server Management Studio. When I attempt to connect to tcp:sql5.hostinguk.net, 1433 nothing shows in netstat at all. There is an option to encrypt the connection in the connection properties tab in management studio, when I enable this I do get an entry in netstat -an, see below:
TCP 81.105.102.47:1138 217.194.210.169:1433 TIME_WAIT
TCP 81.105.102.47:1139 217.194.210.169:1433 TIME_WAIT
TCP 81.105.102.47:1140 217.194.210.169:1433 TIME_WAIT
Amost as if it's trying the different ports but you get this time_wait thing. The error message is more meaningful and hopefull because I get:
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.) (.Net SqlClient Data Provider)
I would expect this as the DNS has not been advised to encrypt the conection.
This is much better than the : Login failed for user 'COX10289'. (.Net SqlClient Data Provider) that I get, irrespective of whether I enter a password or not.
This is on a XP machine trying to connect to the remote webhosting company via the internet.
I can ping the server
I have enabled shared memory and tcp/ip in protocols, named pipes and via are disabled
I do not have any aliases set up
No I do not force encryption
I wonder if you have any further suggestions to this problem?

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??

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.

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 was able to log in to SSRS report manager. But i was unable to run a report i designed on report builder.
It prompts for login when i wanted to run the report and i used the same windows authentication to sign in
It will show me the parameters but when i click on view report it gives this error
"Data source 'DataSource1': An error has occurred.
Details: Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: Cannot create a connection to data source 'DataSource1'. ---> System.Data.SqlClient.SqlException: Login failed for user 'Acc-11Admin'."

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? Thanks!
