Geneva Framework: Building A Custom Security Token Service


A Security Token Service, or STS, acts as a security gateway to authenticate callers and issue security tokens carrying claims that describe the caller. See how you can build a custom STS with the "Geneva" Framework.

Windows Identity Foundation (Claims Based Authentication) for Reporting Services



I see that SQL Server 2008 R2 Reporting Services now supports Claims Based Authentication in Sharepoint 2010, meaning that end users can authenticate with Sharepoint using Claims Based Authentication, and use the same security tokens to connect through to Reporting Services.

I assume that behind the scenes Sharepoint is using Windows Identity Foundation (WIF - formerly codenamed "Geneva") to handle the authentication, and passing this on to Reporting Services.

I'm keen to use Windows Identity Foundation to authenticate with Reporting Services without Sharepoint. We have an existing ASP.NET web application, and we'd like to call Reporting Services from that, passing on the Windows Identity Foundation credentials of the user logged into our web application.

I've done some work on setting up a custom security extension using Forms Authentication (based on the sample), but am not sure how to proceed from there.

Google/Bing hasn't been helpful. Can you please point me to some guidance on how to set up Windows Identity Foundation authentication for Reporting Services?<

Claims Based Authentication (CBA) and Web Services Authentication


I'm planning to use CBA to do authentication and authorization to a document library.  For example, if you have the claim type 'location' equal to 'London' then you are granted access to a folder.  Simple, and it works great from the out-of-the-box web browser interface. 

The question is, can the Web Services interfaces also accept a signed SAML token and use those attribute to do authentication and authorization?  I would prefer to use the CMIS interface where possible.  I understand that the web services are based on WCF, which leads me to believe I can just modify the web.config to add in WCF directives for ws2007HttpBinding->security->message, but will the SP web services code respond by using the identity in the message? 

What I have noticed so far, is that the CMIS interface has directives for only impersonation only.  Since CBA identities do not map to windows accounts, I thinking I'm barking up the wrong tree.  I'm not dead set on CMIS, so if there are other web services available to do CBA, I'm all ears.

There's not a lot of practical material on this, and I'm currently working on a PoC to acheive this goal.  Any help would be greatly appreciated. 



Building a Searchable Phone Directory with Windows SharePoint Services

I want to continue to build out the intranet site we've started in our previous articles. A standard item in every intranet is a staff/employee list. Most companies implementing Windows SharePoint Services (WSS) are large enough to have a database that contains all employees. We will use the aggregation features of SharePoint to include data from this database into our intranet.

Building a 3-Tier App with Silverlight 3, .NET RIA Services, and Azure Table Storage

Silverlight 3, .NET RIA Services, and Windows Azure Services Platform makes a 3-tier Cloud application easier to build: Silverlight 3 as presentation tier, .NET RIA services as the business logic and data access tier, and Windows Azure Table as the data storage tier. The sample application in this article demonstrates the architecture with a simple Survey application with all these technologies working together from Windows Azure.

services based architecture


was giving a though on using ajax enabled wcf services as part of architecture

generally wht im using

is UI-> BL-> data access


is it suggestable to use wcf services layer instead

of BL

nd hv UI-> services-> data access

related to asp.net


would like to no pro's and con's of doing this thing.

is it suggestable to do it.

Claims-Based Apps: Claims-Based Authorization with WIF


Over the past few years, federated security models and claims-based access control have become increasingly popular. Platform tools in this area have also come a long way. Windows Identity Foundation (WIF) is a rich identity model framework designed for building claims-based applications and services and for supporting active and passive federated security scenarios.
