P&aacute;draic Brady's Blog: Yadis: Service Discovery for Identities like OpenID
521963
P&aacute;draic Brady has posted a two part look at a service discovery process as it pertains to things like OpenID via Yadis.   From part one:   This first entry is an examination of Yadis, a Specification which is relied upon by OpenID. Of course Yadis is a topic of its own, since it is also used by Light-Weight Identity (LID), sxip Identity, and mIDm. You can bet more will join in once Yadis becomes more firmly established.   In this first part, he talks about what Yadis is, how it can help with service discovery, and how it would follow a "breadcrumb trail" to get to the information it needs (like getting the actual Yadi slocation from the initial OpenID request).   From part two:   After all this fuss and running about, it's easy to miss the point of Yadis - getting that final Yadis XRD document that describes the Services associated with a given ID.   Part two looks more at working with the Yadis Resource Descriptor information to grap the Type information out of it for the actual locations you'll needed. He also links to some more information on the Yadis specification in PDF form.

Stefan Esser is trying to clear up some confusion in a new post to the PHP Security Blog today about his stand on enabling open_basedir on your PHP installation.   From time to time I get the question why I recommend enabling open_basedir and on the other hand call it a solution flawed by design. This is actually a good question, because the untrained PHP user might get a little bit confused about this and might believe that I change my opinion on a daily basis.   He talks about his reasoning - how it does it's job protecting PHP developers from being able to get to those file, but how it's also flawed with issues due to some 3rd party libraries that have their own problems.

Password complexity be damned Yahoo! has pledged to support OpenID from the end of the month, giving a massive boost for the online identity framework that aims to cut password headaches.â¦

Dave Dash has posted a quick script to help with an integration of openID into your application - well, really just to read the response back easily.   I'm working on implementing openID for reviewsby.us and for use in symfony apps. One thing I was having trouble with was parsing key value pairs, which is one of the requirements to reading responses. It's a fairly easy task, but [PHP][] offers so many ways to do this.   He notes the spec for how the results are returned and shares his code (based around a regular expression) that goes through the response and separates things out into key/value pairs automatically.

People with a Yahoo user name and password will be able to use that ID information to access non-Yahoo Web sites that support the OpenID 2.0 digital identity framework.

Yahoo appears close to implementing OpenID, a Web authentication standard that relieves people of the need to remember multiple passwords to log into different Web sites.

As mentioned by Derick Rethans on his blog today, there's some new versions of several (five) of the components in the next version of the eZ Components framework:   In the just released alpha versions you can find new features, such as better support for OpenID, a Database backend for OpenID authentication, a validating method for e-mail addresses, SMTP authentication support for DIGEST-MD5, CRAM-MD5, NTLM and LOGIN and encoding support for e-mail headers.   He also mentions other goodies like tree structure handling and functionality to support WebDav connections. Check out their roadmap to get a better idea of what's to come.

Those in the New York area might want to check out a new post Daniel Krook has concerning his talk he'll be giving on native XML databases at next week's New York PHP User Group meeting.   The presentation follows a mailing list thread and resulting blog post that generated a lot of interest and discussion on the topic. It should be a great talk for database administrators, application developers and content producers alike.   According to the summary of the talk, he'll be discussing what XML databases are good for and why you might choose them over a normal database. For more information on attending, check out the NYPHP User Group website.

Paul Jones is rejoicing a bit about the OpenID and Typekey functionality Wez Furlong shared just the other day on his blog.   Wez Furlong gives us good news about implementing the math functions needed to support TypeKey and OpenID more directly within PHP.   Paul also mentions that the Solar framework has also had the Typekey support integrated for a while now (as an adapter) that uses the "big-number math functions" currently available to PHP developers. Wez's solution, however, would just about make those obsolete.

Alexey Zakhlestin gave a talk for the PHPThinktank IRC channel recently on the topic of YAML, PHP, and some of the work that he's done combining the two.   It happened a bit of spontaneously, so noone was invited. It was my first try, to make introduction to yaml for php prgrammers, and if there is more interest I will give another talk which will cover more details, this time with proper scheduling :)   You can check out the log of the discussion for his entire talk (covering topics like what YAML is, where to get more information on it, some of its features, and a mention of the Syck library for parsing it).
