of its own built-in authenticating server, many AFS cells are
planning for migration from the old authentication style to the new Kerberos-5
mechanism. This article gives a comparative view of the old OpenAFS commands
and their respective new Kerberos-5 commands, specific to authenticating
entities. This comparison would help OpenAFS and IBM AFS systems

user and group authentication to DB2 through the use of a security plug-in
called db2auth. The plug-in uses a DB2 database for storing authentication
information instead of an external authentication repository, such as an
operating system or Kerberos. The plug-in allows for a smoother migration from other
database software such as MySQL, which also stores authentication information
within the database. This article also describes how the support in TE for the
db2auth plug-in was implemented. [2009 Nov 13: Updated to show Linux support.

Source: developerWorks : XML : Technical library XML was born in 1998 when it became a Worldwide Web Consortium (W3C)
recommendation and the IBM developerWorks Web site was launched the following year. Over those 10 years, the XML zone has hosted over a thousand articles, tutorials, and tips. We've covered technology, tools, standards, products, best practices, predictions, evaluations, and developer experiences, and have supported a variety of forums. A 10-year birthday is a good time to look back at some of the authors who made the XML zone what it is.
Source: developerWorks : XML : Technical library XML documents are frequently validated against either a DTD (less likely) or an XML schema (more likely). Recently, a new technology called Content Assembly Mechanism (CAM) has emerged. It is endorsed by the Organization for the Advancement of Structured Information Standards (OASIS). CAM represents a step up from XML schema because it provides even more flexibility in defining both the semantics of an XML document and the business rules associated with the actual data content. Take a broad overview of CAM, including its benefits over the alternatives, in this article.

Learn to retrieve, add, delete, and modify contacts through a custom PHP application with this API in an application context.
Source: developerWorks : XML : Technical library XMPP is a open protocol for XML-based communication over the Internet.
Although it is most popular as an instant-messaging protocol, you can use it as a general
messaging service, as well. Discover the ins and outs of XMPP, and learn how to use it for
simple messaging.
Source: developerWorks : XML : Technical library The ability to specify, check and act upon constraints is vital to
ensuring the overall quality of healthcare information. The Health Level 7
(HL7) Clinical Document Architecture (CDA), described through XML Schema,
allows the specification of constraints through HL7 Templates, which can be
implemented in Schematron. Schematron can be applied through XSLT. This article illustrates software and
hardware solutions for constraint checking in the HL7 CDA. The two
solutions are demonstrated in an SOA that
includes both successful and failing XML Schema and Schematron constraint
checks. The article evaluates the application of constraints in the HL7 CDA
and identifies some categories of constraints that require further investigation.
The outcome of this evaluation shows that the ability to specify, check, and act
upon constraints through Schematron complements XML Schema processing. The two
constraint approaches are very useful and practical, and should therefore be
pursued further.
Source: developerWorks : Web development : Technical library Asynchronous JavaScript and XML (Ajax) is everywhere, from the local newspaper to sites that CEOs surf. Contrary
to popular belief, it isn't rocket science, especially with the right library. Explore the
popular Yahoo! User Interface (YUI) and Dojo libraries, and learn how they can simplify typical Ajax techniques
and make JavaScript easier to work with. Discover why you should use a library in the first
place and how to choose among libraries. Get some specific examples from YUI and
Dojo, as well.
Source: developerWorks : Open source : Technical library To conduct software reviews and inspections smoothly, you need a set of
tools that includes techniques for reading phases, roles, and software tools.
Most people think review and inspection must be manual, with little room for
tools and automation. However, there are software tools to make reviews and
inspections more efficient, structured, and at least semi-automated. This
article introduces a toolset for code reviews that includes the techniques and
software tools that you need.
Source: developerWorks : Open source : Technical library Have you ever wished that Cookies were a lot bigger so you could store
more data on the client, or that you could make cross-domain Asynchronous
JavaScript and XML (Ajax) calls? If
so, you are in luck. Both of these techniques can be accomplished using
invisible Flash. So, just what is invisible Flash? It is not really invisible,
however, it is 1 pixel by 1 pixel, which makes it pretty hard to see. And, it can
be used as a way to tap into the capabilities of the Flash Player. In
this article, you will learn how to build invisible Flash files that let you to store up to 100 KB of client-side data and make cross-domain Ajax calls
-- all without your users ever knowing that Flash is being used.
Source: developerWorks : Open source : Technical library The e4 project is the next generation of Eclipse. e4 will provide a platform for pervasive
component-based applications and tools. In this article, learn about
some of the new features in e4, such as XWT and declarative styling.
XWT is a new toolkit for defining the structure of SWT/JFace
applications declaratively in XML, while
leaving the business logic in Java code. It can separate the model and
representation while saving much of the layout and UI related code originally
developed for your SWT/JFace application.
An example application walks you through the XWT interface and data binding
feature.
Source: developerWorks : Open source : Technical library PHP developers commonly require the services of an Extensible Markup Language (XML) parser in their code. Along these lines, they frequently find it necessary to validate XML input. Fortunately, you can easily accomplish this in PHP. This article shows you how to validate XML documents within PHP and determine the cause of validation failures.
