I think DeltaSpike will end up having simpler generic API for authentication and authorisation and it will be possible to plug PicketLink IDM to handle all the calls. Then for identity model and IDM operations (user, group, role handling) it will be API defined in PicketLink IDM project to be used.

For the pure IDM aspect there is work done by Viliam in JQuery that should be very easy to adapt: https://github.com/vrockai/picketlink-idm-webapp IIRC he was willing to move this repo into picketlink space. I will try to check next week with him and ask him to donate the repo. For authorisation part Shane already started to work on example web application as part of his DeltaSpike work. > >> >> -Jay >> >> >> On Jul 27, 2012, at 10:20 AM, Pete Muir wrote: >> >>> >>> Begin forwarded message: >>> >>>> From: Pete Muir <pmuir(a)redhat.com&gt; >>>> Subject: DeltaSpike, IDM, Authentication and Authorization >>>> Date: 27 July 2012 15:17:42 GMT+01:00 >>>> To: security-dev(a)lists.jboss.org >>>> >>>> Until recently, it looked like Apache DeltaSpike would define an IDM API, but now it looks like most people are in agreement that DeltaSpike should not cover IDM. >>>> >>>> http://apache-deltaspike-incubator-discussions.2316169.n4.nabble.com/IDM-... >>>> >>>> It would still provide an API and SPI for authentication and authorization, as defined in http://incubator.apache.org/deltaspike/security.html >>>> >>>> >>>> Does it matter that DeltaSpike won't do IDM? >>>> ------------------------------------------------------------ >>>> >>>> The big reason for us to do things in DeltaSpike, is to give our users a portable way to write applications. As DeltaSpike is a collaborative project between individuals and companies, there is lots of effort put into ensuring portability, and provides a good vendor neutral location to do that. If we consider where portability matters: >>>> >>>> * in application code, typically measured by the number of classes, views etc. in a typical application that must be changed to move between frameworks/libraries/runtimes >>>> * in configuration, typically measured by number of files that must be altered to move between frameworks/libraries/runtimes >>>> >>>> Typically the number of classes is much greater than the number of configuration files. >>>> >>>> We can use this to "measure" how much portability matters for a given topic, by looking at the number of files that must be changed to move between frameworks/libraries/runtimes. >>>> >>>> Taking our security topics: >>>> >>>> * Authentication: typically impacts a low number of classes and views.

Perhaps the only real impact on code is accessing user information for display (e.g. the classic "Welcome Pete").
