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...

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...

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...

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...

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...

In my previous post, I had a question for all you: What would happen if Adatum’s FP didn’t supply ACS with the whr parameter? An the answer is: ….. ACS will simply ask the user!   ACS has no way (besides the whr parameter) of knowing where to go next (unless you configured your app with only 1 Identity...

Updates : fixed typos. Clarified how Home Realm Discovery works in this example.   In the previous post , I introduced the basic scenario of using ACS as a federation provider for Adatum (in addition to the one they already have). In this post, I’ll show you more details on how this works, based...

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...

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...
