I spent some time debugging this today, I think I found the problem, but I still have to retrace my steps and do some more testing. In any case, I will be submitting a patch for NetNameResolver and NameLookupFailure in particular, there is something very odd with this exception.

No teaching, permanent position with tenure after a probation period of 12 Months. Requirements: - A PhD - In practice, the competition is very hard and a strong academic CV is needed on a level that requires, besides a very good PhD, at least one to two years of postdoctoral research experience. CR1 âYoung experienced scientistâ ----------------- The CR1 position is for confirmed researchers with experience in research, strong international recognition, and established leading abilities. No teaching, permanent position with tenure after a probation period of 12 Months. Requirements: - A PhD and four years of research experience. - A very strong academic CV. PROFILE ------------- The candidate must have a doctoral degree, a strong background in Computer Science, and internationally significant research achievements in software engineering (particularly software evolution) and/or programming languages. Duties include: -Research (no teaching). -Help manage the RMoD Research group. -Be involved with the self-governance of the Inria Lab and Inria as a whole. -Guide PhD students (and therefore get a French habilitation to be able to formally supervise PhD students). -Help acquire additional funds for PhD students, Postdocs and Engineers. -Transfer research results to the real world. MISSION -------- Join one of our two lines of research: Tools for Software Maintenance or New Programming Language Constructs for Software Evolution. THE REGION ---------- Lille is strategically located in Northern Europe with train connections to Paris (1h), London (1h30) and Brussels (30 min.) The Nord Pas de Calais region is a dynamic area in both industry and research for computer science with companies that are european leaders in their branch. Lille, the capital of northern France is an attractive metropolis of over 1 million inhabitants. Cost of living in Lille is lower than that of very big cities such as Paris and London. THE TEAM -------- RMoD is an Inria research project team. It consists of 6 permant researchers (Inria CR and DR, as well as University Assistant Professors) and Engineers, postdocs and students (Master and PhD). RMoD is an international team with more than 20 members from six countries.

Re: [Pharo-project] [Update] Zinc-SSO OAuth 1.0 & OpenID Alpha Code & Live Demos

by CÃ©drick BÃ©ler

Hi Jan and Sven, To my knowledge, CAS is mainly used in for uPortal wich is "the leading open source enterprise portal framework built by and for the higher education community", see http://www.jasig.org/uportal In France, there's a system called ESUP [1], an "Environnement NumÃ©rique de Travail" (don(t know the english equivalent). To me it's no more than a portal for web applications with rights/customization according to UNI profile (student, professors, researchers, ...). I hate ESUP, it's full Java and XML, looks old to me and not ergonomic. It's Open source but cost a lot to deploy and maintain... We don't have setup this system yet in our Uni but there is already the SSO part, (Java CAS server) wich does the job... I also noticed in some other UNI that they don't always use ESUP but CAS is their SSO... If I had a Pharo client, I could prototype quicker a "ENT like" so I can show IT people that ESUP is far from necessary ! Porting such client in ST seems not possible in a reasonnable time for me and the outcomes are not guaranteed (also time is missing)... I actually do it now in PHP :( I also think that doing an ENT in Pharo/Smalltalk could be a nice opportunity for web companies to sell such products to UNI... FYI, the installation of ESUP + "cassification" of some apps that integrates this portal is sol between 25 and 35kâ¬ ! To sum up, I think having a CAS client would be nice only if a company plan to make and sell ENT like system (ObjectFusion, beta9, Inceptive, agilistic...). I caon't really ask for prototype needs... Cheers, CÃ©drick [1] ESUP exemples: https://www.google.fr/#hl=en&tbo=d&output=search&sclient=psy-ab&q=ent&oq=en… [2] some cas clients: http://www.jasig.org/cas/client-integration [3] ruby version, rubycas : https://github.com/rubycas code.google.com/p/rubycas-server/ code.google.com/p/rubycas-client/ [4] CAS centralize authentification, is cross domain, OpenID decentralizes authentification http://stackoverflow.com/questions/2033026/sso-with-cas-or-oauth/3181557#31… [5] ENT on french wikipedia... http://fr.wikipedia.org/wiki/Espace_numÃ©rique_de_travail > I'm not familiar with CAS and I don't know where it is used. Currently Zinc-SSO only implements the client/consumer side of the different protocols. Are you just looking for a client side implementation of CAS in Smalltalk or also the " identity provider" side? It would be only the client side. > > Jan. > > > > > > Any chance for a CAS implementation ?

From what I remember it is comparable in complexity to OAuth1 and OpenID (OAuth2 is simpler).

Provider is mainly the java server... I don't know a public one, I have credentials for my uni server and I can eventually give my credentials to try... I've already asked for demo account to the IT staff and they refused ! > > Regards, > > Sven > > PS: Remember our DropBox experiments from so long ago ? I might try using Zinc-SSO to do it, provided I find some time ;-) remember too... sad I stopped since we lost last versions... still time is missing...
