Using windows authentication to access SQL when using ASP.NET 4.0 via COM+


I am using SQL Server 2008 under windows authentication, front end is ASP.NET which uses COM+ to access database.

COM+ components are configured to run as domain user.

When looking through the logs (SQL Profiler), I can see the login name as the configured identity instead of windows indentity.

I have got Website running under "Intergrated Windows Authentication" and database is running locally on webserver.

Web configure contains entry for <identity impersonate="true"/>.

My connection string is

connectionString="data source=db01\test01;initial catalog=test; integrated security=SSPI;persist security info=False; Trusted_Connection=Yes"

Any ideas?




Access denied when user clicks refresh BDC column button

Access denied occurs with any non Site Collection Administrator regardless of rights.  It only occurs in this site collections, others they are able to refresh.  In this particular collection they can add a BDC column to a list, edit an item and place/resolve a value in the bdc col; but when they refresh they are given an acess denied.  Any thoughts on what they need read access to?  This goes away if I give site admin privs (dont want to do that) or give them read only access on the web application (dont want to do that either).

With Anonymous access disabled, is there any way to use an AJAX-enabled WCF Service?

I have a website where anonymous access is disabled but I want to user an ajax-enabled WCF service. Configuring the service's binding security to use "TransportCredentialOnly" with clientCredentialType="Windows" seems like the obvious thing to do; indeed, many posts in various places suggest this approach. Unfortunately, however, it doesn't work. I always get the error "Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service." How can I configure the service to function correctly. I'm running IIS 7.5 with .Net framework 4.0. Thanks.

Planning common membership provider for different authentication providers

I am trying to implement form based authentication (FBA) membership provider that is able to support multiple authentication mechanisms. Take it as an self-training experiment. In this posting I will introduce bases of my experiment and introduce my current plans and ideas. Why membership provider for multiple authentication mechanisms? There are many people in the world who are users of some social network or some open services provider. Today Facebook and Twitter are very popular social networks. Also Google and Microsoft Live services are very popular although they are not social networks. But all mentioned systems provide their own authentication channels also to other applications. The question is: why should I have another username and password if I have already one at some of systems I mentioned before? Here, in Estonia, we are building local Microsoft community portal with local Microsoft. We analyzed the situation and decided to use Live ID as authentication mechanism in our portal. We were a little it worried too because we were afraid that there are load of users who are not happy with Live ID as authentication mechanism. And guess what - as time has shown us there is no reason to worry! Our ~2000 users (Estonia is small country) are all happy with Live ID and the ones who doesn't have Live ID yet can go and join Live ID - it's free. If you have no idea where I l

Authentication for External Users to Access MOSS 2007 Resources

Our MOSS 2007 supports users from two domains that authenticate using windows.  Our clients WindowsXP in domain#1 and WindowsVista in domain#2 (which has presented problems authenticating to MOSS 2007.  I would like to give access to external users outside of those two domains.  However, our management does not want to establish trusts between domains.  What would be the best practice to accomplish this?  Additionally, will MOSS 2010 or Forefront resolve these issues?

Reporting Services 2008 - Anonymous Access

Hello,   In SSRS 2005 I was able to grant anonymous access to my reports by changing the authentication mode for the Reporting Services virtual directory in IIS to Anonymous and then adding the 'account used for anonymous access' to the permissions on the appropriate Reporting Services directories (in report manager).   Now with SSRS 2008 there are no virtual directories in IIS.   I tried to follow the instructions given:   http://technet.microsoft.com/en-us/library/cc281310.aspx (Authentication Types in Reporting Services)   Which instructed me to use the custom AuthenticationType, and following the instructions here:   http://technet.microsoft.com/en-us/library/cc281383.aspx (How to: Configure Custom or Forms Authentication in Reporting Services)   which just got me an error: The Authentication Extension threw an unexpected exception or returned a value that is not valid: . (rsAuthenticationExtensionError) Get Online Help For more information about this error navigate to the report server on the local server machine, or enable remote errors   Any ideas on how to set up anonymous access to SSRS2008?   Thanks for any time and help!   -Tim

Anonymous Access to "Event Export" on sharepoint calendar display page

I am using a SharePoint calendar with events added in the list. When an anonymous user tries to use "Export Event" on the display page ,the user is prompted for a login. Is there a way that an anonymous user can download the .ics file without logging in ? Is anonymous access even possible ?    

SharePoint 2010 Claims Based Authentication - anonymous site is prompting for CBA auth when opening

Hi, I have CBA setup successfully on my sites.  One site is setup for anonymous access and I have disabled "client integration" on that web application. I have a list of MS Office documents on a wiki.  When I click on one I am asked to either save or open or cancel.  Saving works fine but when I choose open, it launches the associated MS Office app.  I am then prompted for a login from CBA.  I can click cancel and the logon screen appears again.  After clicking cancel the 2nd time the document appears in the MS Office app, Word in this case. My question is how do I prevent my users from being prompted for a CBA login when clicking on these files and opening them in the native app on their machine?      --TR

The HTTP request is unauthorized with client authentication scheme 'Anonymous'

I am trying to do a soap request from a WebCTRL server. I went to add a service reference, entered the URL to my wsdl and (after prompting me for a username and password) it added the reference and I can create an instance of the service object and makes calls against it.   Dim eval As New WebCTRL_Eval.EvalClient eval.Open() Debug.Print(eval.getValue("#reception_40/lstat"))   I get this back from the server, on open and getvalue.   The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Basic realm="SOAP Access"'.   I understand that it is the HTTP authentication that I need to setup or configure, but just dont understand how to do it.   I have tried eval.ClientCredentials.UserName.UserName = "myusername" eval.ClientCredentials.UserName.Password = "mypassword"   How do I change the client authentication scheme and provide my credentials to it?   Here is what is on my app.config file.   <system.serviceModel>  <bindings>   <wsHttpBinding>    <binding name="EvalSoapBinding"     bypassProxyOnLocal="false"     transactionFlow="false"     hostNameComparisonMode="StrongWildcard"     maxBufferPoolSize="524288"     maxReceivedMessageSize="65536"     messageEncoding="Text"

Anonymous access on Excel Viewer web part for a no access .xslx file?

I have a public facing SharePoint 2010 Enterprise website with anonymous access enabled. I'd like to present information (a pivot chart) from an .xslx file using the Excel Viewer Web Part. It works fine when I place the .xslx file in a document library that the anonymous users can access. I would, however, like to remove anonymous access from the .xslx file and only expose the chart from the .xslx file using the Excel Viewer web part. When I alter the library permissions to remove anonymous access to the library that holds the .xslx file, the Excel Viewer web part displays an "Access Denied" message to the anonymous user. Is there some other way to achieve this?

Anonymous access - User prompted for login after click in web part area

I have a MOSS2010 site, internet-facing using anonymous access. I've found workarounds to many of the anonymous access issues I've come across, but I don't know how to fix this one. Any ideas or assistance would be appreciated. A user visits one of my pages with a OOB webpart. If they click within the area for that web part, essentially selecting the web part, it prompts for a login. I don't want my users getting prompted for a login, but I don't know why they're being prompted in the first place. According to the logs, it looks like it is trying to access _layouts/wpribbon.aspx. They aren't clicking on the items (titles aren't clickable), it's the area within the web part box. Can I make that area non-clickable?? Go to: www.carlile.biz/careers/pages/current-openings.aspx Click on the area around the Locations or the Current Openings listed. Either will prompt for a login. Even with a valid login, the view does not change and no further options are presented.

Anonymous Access & Web Service Errors

Getting errors on all my InfoPath web services now that I've enabled Anonymous Access at the Web Application level -- not on the Site Collection itself (the other Site Collection is Anon enabled). I found this thread in the pre-Sharepoint 2010 forums. http://social.msdn.microsoft.com/Forums/en-US/sharepointinfopath/thread/14d2c1c2-32d4-430b-a191-c01e1ade52fa Does anyone know which parameters or changes I need to make in 2010? Many thanks...

Custom Web Part doesn't work with in anonymous access

Hi there, I have a custom webpart in a farm solution deployed to my site. Anonymous users should be able to view the site, however they can't because they are required to login due to the custom web part. If i remove the webpart from the page, anonymous users can view the site perfectly without the need to login. There is nothing really special about the webpart. It's a visual web part which uses the site and it's web data to display a sort of menu. Any idea? Thx in advance! Brecht

Changed to claims based authentication, now I can't access my site. Please help! Time is of the ess

I am in a pretty big bind. I have a sharepoint 2010 site, that was using classic windows authentication. It worked fine from the inside, and I was able to extend it to the outside and it was using https with an SSL certificate. However, my performancepoint reports and my external lists weren't working when the site was accessed from the outside. Apparently this is a known issue with using classic authentication on the outside, so I tried to switch over to claims based authentication. I followed this guide: http://blogs.technet.com/b/wbaer/ar...point-2010.aspx I obviously changed the contoso stuff to my domain name, and changed all of the config files. The problem is, now I can't access the site at all from the inside or the outside. Here is the error I get in my logs: code: An exception occurred when trying to issue security token: Could not connect to [url]http://localhost:32843/SecurityTokenServiceApplication/securitytoken.svc/actas.[/url] TCP error code 10061: No connection could be made because the target machine actively refused it .
