Windows Azure Pack Authentication Part 3 – Using a Third Party IdP

In the previous installments of this series we looked at how Windows Azure Pack authenticates users and how it’s configured out of the box for federation. This time around we’re going to look at how you can configure federation with a third party IdP. Microsoft designed Windows Azure Pack the right way. It supports federation with industry protocols out of the box. You can’t say that for many services, and you certainly can’t say that those services support it natively for all versions – more often than not you have to pay extra for it. Windows Azure Pack supports federation,…

Windows Azure Pack Authentication Part 2

Last time we looked at how Windows Azure Pack authenticates users in the Admin Portal. In this post we are going to look at how authentication works in the Tenant Portal.

The biggest detractor to Single Sign On is the same thing that makes it so appealing – you only need to prove your identity once. This scares the hell out of some people because if you can compromise a users session in one application it’s possible to affect other applications. Congratulations: checking your Facebook profile just caused your online store to delete all it’s orders. Let’s break that attack down a little. You just signed into Facebook and checked your [insert something to check here] from some friend. That contained a link to something malicious. You click the link, and…

Making the Internet Single Sign On Capable

Every couple of weeks I start up Autoruns to see what new stuff has added itself to Windows startup and what not (screw you Adobe – you as a software company make me want to swear endlessly).  Anyway, a few months ago around the time the latest version of Windows Live Messenger and it’s suite RTM’ed I poked around to see if anything new was added.  Turns out there was: A new credential provider was added! Interesting. Not only that, it turns out a couple Winsock providers were added too: I started poking around the DLL’s and noticed that they…
