  • Blog Post: Claims Identity Guide–Hands On Labs

    Training content based on our guides has been as popular as the content itself. You can now download the “Release Candidate” for labs corresponding to the new guide . The labs are more than just a mirror of the guide. We took the opportunity of adding a few things that complement and extend what is explained...
  • Blog Post: Authentication in WP7 client with REST Services–Part II

    In the previous post I covered the “semi-passive” way for authentication between a Windows Phone 7 client and a REST service. This post completes the information with the “active” way. There’s nothing unexpected here really: We call the Identity Provider using a RequestSecurityToken message (RST) We...
  • Blog Post: Authentication in WP7 client with REST Services–Part I

    In the last drop, we included a sample that demonstrates how to secure a REST web service with ACS, and a client calling that service running in a different security realm: In this case, ACS is the bridge between the WS-Trust/SAML world (Litware in the diagram) and the REST/SWT side (Adatum’s a-Order...
  • Blog Post: Drop #2 of Claims Identity Guide on CodePlex

    Second drop of samples and draft chapters is now available on CodePlex. Highlights: All 3 samples for ACS v2: (" ACS as a Federation Provider ", " ACS as a FP with Multiple Business Partners " and " ACS and REST endpoints "). These samples extend all the original "Federation...
  • Blog Post: SaaSGrid and Identity

    Apprenda’s SaaSGrid is now “claims enabled”!  This is fantastic news. Any SG customer can now enjoy the benefits of claims based identity: simpler user management, easy federation with business partners, support for multiple identity providers, greater interoperability, etc. SG support for claims...
  • Blog Post: Single Sign Out–WebSSO

    While reviewing all the existing samples we’ve noticed that our implementation of Single Sign Out was kind of….weak.  It wasn’t really fully implemented and wasn’t very clear what was happening either (or what it should happen) We’ve fixed all that now in scenario 1: WebSSO . Things get more complicated...
  • Blog Post: ACS as a Federation Provider – Claims transformation

    To work properly, a-Order needs a number of claims to be supplied: User name Organization Role The "Organization” claim is used to filter orders belonging to a specific customer of Adatum. For example, Litware users (like Rick) will eventually end up with a token containing a claim with “Organization...
  • Blog Post: Access Control Service as a Federation Provider

    The first scenario we are working is using ACS as a federation provider. This is an extension of the current chapter on Federation . The basic scenario is the following: Adatum has an Order processing app (a-Order) that is already claims enabled. Adatum wants their partners to be able to access a-Order...
  • Blog Post: Our next project – Claims based Identity and Access Control

    Not surprisingly maybe, security in general, and authentication & authorization in particular, is a consistently highly rated concern for our customers. These concerns are especially elevated  with those considering the cloud, because they don’t have as much control on the cloud as they would...
  • Blog Post: Claims Identity Guide samples updated

    I’ve just uploaded to CodePlex updated samples for the Claims based Identity Guide . This have all been adapted to work on Visual Studio 2010, .NET 4.0 and MVC 2.0. See here for downloading the bits. From the release notes:                                   ...
  • Blog Post: Windows Azure Architecture Guide – Part 2 – TailSpin Surveys – AuthN and AuthZ

    Tailspin Surveys is a multitenant, SaaS solution, targeting many different customers. Some of these customers might be “enterprise” with “Big-IT” and are likely to demand advanced integration capabilities for identity (e.g. identity federation). Others, potentially smaller, are likely to not require...
  • Blog Post: WIF and MVC – How it works

    I got a few questions from people on how the “ Federation with Multiple Partners ” sample of the guide works, so I figured I would just write it down in one place for eternity. The guide explains all sequence in quite some detail (see pages 88 to 97), but sometimes a diagram is more helpful, so here...
  • Blog Post: Windows Azure Guidance – First version of a-Expense in the cloud

    Available for download here , you’ll find the first step in taking a-Expense to Windows Azure. Highlights of this release are: Use of SQL Azure as the backend store for application entities (e.g. expense reports) Uses Azure storage for user profile information (the “Reimbursement method” user preference...
  • Blog Post: Windows Azure Guidance – a-Expense “before” on CodePlex

    First build of our samples is now available on CodePlex . This initial version is the “before the cloud” baseline application, so you won’t find anything related to Windows Azure here. This week we will take this simple baseline and start moving it to the cloud. Goals for this next iteration are to:...
  • Blog Post: Just Released – Claims-Identity Guide online

    The entire book is now available for browsing online on MSDN here: http://msdn.microsoft.com/en-us/library/ff359115%28lightweight%29.aspx Now, to be honest, it doesn’t look as nice as the printed book (small preview here):     But everything is in there! (and doesn’t look that bad at all either...
  • Blog Post: ADFS / WIF on Amazon EC2

    Steve Riley’s post on growing interest from Amazon customers on identity federation is consistent with what I hear from our own customers. As part of our project , we actually tested the two scenarios he describes on EC2: “I imagine most scenarios involve applications on Amazon EC2 instances obtaining...
  • Blog Post: Updated code samples & chapters for Claims Identity Guide – Release Candidate

    In synch with the availability of ADFS V2.0 Release Candidate , I’m very happy to announce that we are posting a new update of the guide. Our own “RC”. You’ll find new samples and new chapters. Both content complete now. We are now covering the following scenarios: Single Sign on for web applications...
  • Blog Post: Updated RIA and WIF samples – Part I

    Some time ago, I put together a simple demo integrating WIF in RIA Services. Now RIA is a Beta and there’s a lot of cool stuff in there. The good news from an identity perspective is that it just works :-). I’ve been playing a little bit with a couple of new samples and with the previous (updated) HRApp...

    New updated chapters & samples are posted on CodePlex . The samples are all updated for WIF RC and include new scenarios and technologies (e.g. web services with WCF and web sites with MVC).

  • Blog Post: Claims based Identity & Access Control Guide – Updated drafts & samples available

    Yesterday, we uploaded a new release of the Guide and the samples. You can download the content from here . (Note: if you downloaded them yesterday, you might want to check again.

    We finally have a CodePlex site for sharing early content with you all. Check the downloads section for: A few intro chapters (some of the “theory”, technologies and protocols behind claims based identity) The first scenario (roughly described in my post here , but better and nicer, and written in English...
  • Blog Post: Announcing new project – patterns & practices - Claims based Authentication & Authorization Guide

    For the next couple of months I’ll be working on a new project here at patterns & practices , developing a new guide for claims based authentication and authorization. I’m personally very happy to be working on this project, for many reasons. I believe frameworks like “Geneva” (previously known as...
