I noticed that the following is an issue thru which people often run: when you show an aspx page (or any server content in general) in a dialog by mean of the javascript ShowModalDialog method, at the first postback you usually witness the instance of...

Ahh, I’ve been looking forward for this post for a looong time. We just made available for download the bits of the Beta of “Zermatt” Developer Identity Framework . “ Zermatt ” is the codename of a .NET framework that helps developers build claims-aware...

From time to time it's healthy to challenge the assumptions, and look at (allegedly) familiar things with new eyes. Few weeks ago I had to do just that with the idea of authentication : I wanted to shake a bit an audience of architects, and make them...

We just recently published a list of sessions for MIX08 . Among those, there is one that I hold especially dear: I had the luck to work with Paul, his team and the WCF team in the last months, specifically on how to leverage the web capabilities...

After Japan, this year I have the pleasure to present also at TechEd Europe in Barcelona. I have a breakout session ( SBP309 ) on Thursday morning, and an interactive session ( SBP11-IS ) around lunch time. From the title & abstract it may seem your...

[updated] In short: I describe why claims are important for every developer and architect (not just the security expert), and I provide some heuristics for helping everybody to reason about claim based systems. I don't think we did an exceptionally...

Another flight, another post! While I'm hurdled at impossible speed over the Atlantic toward US, I find myself to reflect about the breakout session I delivered 10 days ago at TechEd in Barcelona. And I better do it fast, since the seat power plug can...

Hello everybody [:)] before re-heating up the discussion on SO, I thought I could use a little help here: in your opinion 1) what is represented in the three pictures below? 2) which one of the three you like best? 3) do you think there's too much information...

Ah finally. I waited for this moment a looong time :-) the first draft of "Understanding Windows CardSpace" is available in prerelease online, on Safari Rough Cuts . More details below. It's already few weeks that our book, " Understanding Windows...

[Edit: Added Silverlight SxS con WPF/E] In short: this is a tutorial on invoking Cardspace from a Sliverlight [WPF/E] control and how to use Silverlight [WPF/E] for showing data from a token . So easy that a long haired architect can do it :-) Silverlight...

If you were wondering what kept me up in the evenings of the last few months, wonder no more :-) The Identity Developer Training Kit is a set of hands-on labs and resources designed to help developers to take advantage of Microsoft’s identity products...

Do you remember the PDC session in which Kim announced all the new wave of identity products, including Geneva? During that session I showed a pretty comprehensive demo, where  all the products & services worked together for enabling a fairly...

[I know, you must be sick of book -related posts: please bear with me just a bit longer, I think we’re almost done :-)] [UPDATED] YES! I just found under the door mat – wait for it - the very first printed copy of Programming Windows...

[this may look weird at first, but bear with me] The Roman numerals notation emerged with Roman civilization itself, around the 9th century BC, though its roots go all the way back to the Etruscans. It is not an especially handy system: it’s not well...

More occult goodness for your programming pleasure! The Session Mode is a great feature of WIF which is not known as widely as it should be. Sometimes you will be in situations in which it is advisable to limit the size of the cookie you send around....

[for my usual readers: yes, this is Chinese. That's intentional :-)] <对不起我的不对用语> 你好!我叫维托里奥,我建筑学的启动子在Microsoft corp. 我特化是Windows Server,格外Windows Cardspace, WCF, WF和崭新Orcas. 我去年会面了多顾客在上海,深圳,香港,台北,新加坡...我查出了我喜爱中国文明. 我上九月俶识字中文字.我每天读书不过稍微,十分钟.艰巨! 但是我要识字...

Brace yourself, here there's another coming :-) Today I had to explain to my girlfriend the difference between the expressive power of WS-Security as opposed to HTTPS. She's a computer scientist, so even if she doesn't know all the XML mumbo jumbo...

Ahhh, finally. Getting a personalized plate was one of the things I was looking for when I relocated to the States.. and in record time, I got one which pays homage to one of my biggest passions! [:)]

[edit: Caleb points out that I could be clearer in stating that using just the PPID for authenticating requests is truly a bad idea, and I have to agree. Language hardening in progress..] In short: When you register users by using their information...

Here there's the cover sketch for our "Understanding Windows CardSpace" book. As you may have noticed, the Independent Technology Guides series has the tradition of putting an animal on the cover. While all the books of the series have gorgeous cover...

[ EDIT: added some sketch ] In short: I briefly discuss some differences between the password based authentication model and the token based one; then I propose that we lack a proper term for describing some of the transactions enabled by cardspace and...

I promised it , and I'm doing it. In this post I will give a simple walkthrough of developing an STS with the ADFS "2" Identity Framework. If you went to my breakout session at TechEd Europe , you can safely skip this post. I am not going to reveal anything...

[warning: no identity or technical content here] It’s so long that I don’t write a post about gadgets that the term disappeared from my tag cloud. Well, tonight after dinner I took a break from the usual grind and decided to pay homage to this ceremony...

[Disclaimer(): base() { this blog is NOT the source of the official guidance on the Geneva products. Please always check out the Geneva team blog for hearing directly from the product group} ] In the former installment I blabbered a bit about how an...

As promised, the recordings of the main sessions of the latest WIF Workshop are now available  on Channel9! The course starts from the very high level intro you’ve seen various times, and progresses into the deepest WIF training content we’ve ever...
